How to run a JAR file on Windows 10/11 [Quick guide]

  • In order to launch a JAR file on your Windows 10 device, you must first ensure that Jave is installed on your device. You’ll find a link to the most recent Java version in the section below, should you require it. Afterwards, you may discover JAR file openers or executors, of which we have selected a few for you
  • If you don’t want to install any third-party programs, you may use the Command Prompt to accomplish your goals.

If you are unfamiliar with the term “JAR file,” it is a Java archive package format that may include a Java application. If you are unfamiliar with the term “JAR file,” it may be defined as follows: While you can extract JARs using archiving tools, you will not be able to execute a pure Java JAR application in the same way that you would run other applications under Windows. Because this is the case, we’ll go through how to launch a pure Java application JAR file on a Windows computer.

How are JAR files helping you?

A JAR file is a container that allows Java runtimes to include a full program, including all of its classes and resources, in a single source file. Furthermore, the parts included inside a JAR file can be compressed, resulting in quicker download times while also requiring less disk space on your computer’s hard drive. A more succinct definition is that JARs are more advanced archives that operate in a Java environment on your computer.

How can I run a JAR file on Windows 10?

  1. Using cmdin the WindowsSearchtab, choose the Command Promptapp by clicking on it. After that, enter the following command and press Enter to have it executed: java -version is an abbreviation for Java version. Java is now on version 8 update 311
  2. The most recent release is version 8. If you don’t have Java or the most recent version, you can get it for free from the Java website. After you have downloaded the file, click on theInstallbutton. Follow the instructions in the Java setup wizard and then shut the window when the installation procedure is complete. Then, open your browser to ensure that the software is functioning properly.

The most important item you’ll need right now is Java installed on your computer. Java applications will not be able to operate on Windows if this is not installed.

2. Use Java (TM) Platform SE binary

  1. In order to launch File Explorer and the folder that contains the file you need to run, press the Windows key + E. Choose another application from the context menu by right-clicking the JAR file and selectingOpen with from the context menu. Pick Java(TM) Platform SE binaries as the program to open it. To clear the option, choose theAlways use this program to open JAR filescheck box and then hit theOKbutton on your keyboard. As a result, you may now run the specified JAR file, and all other JARfiles will be connected with Java as well.

3. Download a JAR file opener

  1. Obtain a copy of the File Viewer Plus website and click on theDownload Now button. After you have downloaded and installed the application, click on theFinishbutton
  2. Then click on theOpen a filebutton or just drag and drop the JAR file into the application’s window
  3. And finally click on theFinishbutton. Immediately after that, you will be able to inspect the contents of the JAR file and click theExtract Allbutton to save them in a convenient area on your computer’s hard drive.

JAR files may be opened by many different applications; however, File Viewer Plus is our top recommendation because it is capable of opening and displaying over 300 distinct file types. The newly released upgraded version has a slew of capabilities that will save you a significant amount of time while opening, reading, or editing files. Keep in mind that the software supports the most commonly used text, audio, and video file types, as well as archive, source code, and web files, among others.

4. Run a JAR file from the Windows Command Prompt

  1. Enter cmd in theSearchtab, then chooseRun as administrator to launch the Command Prompt with full administrative capabilities. Input the following command (with pathtofilefrom the example substituting pathtofilewith real path of file you wish to run) and press Enter: java-jarc:pathtojarfile.jar

That will open the executable JAR file as long as the executable JAR file has a manifest file that specifies the entry point for the program (the developers should have already included that in the archive.) The JAR file will need to be converted to an executable format if you are creating your own Java applications. The command-line application is essential for troubleshooting and installing applications; however, if it does not function properly, discover how to repair Command Prompt on Windows.

5. Add a third-party JAR executor to Windows

  1. To get the JARX-1.2-installer.exe file, go to the JARX website and click on theJarx-1.2-installer.exe file. To begin the installation, download the file and double-click on it
  2. Once the installation is complete, pick theClosebutton. Now you can just double-click any JAR file to launch it in the same way you would a conventional executable file

There are other executor tools for Windows, such as JARX, that allow you to run JAR files in the same way that you would run any other type of program.

How to get a JAR file for your favorite app?

You can get free JAR versions of virtually any program you can imagine on a variety of websites, and we’ll use Instagram as a basic example to demonstrate this.

  1. To download JAR files, go to a website that provides them, such asJAR Download. Follow the instructions with caution because not all such websites provide clean content
  2. Thus, you should double-check the content with an antivirus and scan the files upon receipt before utilizing them. To access the Java version of the application you’re searching for, choose it from the list. In our instance, it’s the Instagram Java
  3. Yet, Now click on theDownloadbutton, and if you followed our instructions above, you should already be familiar with how to open the JAR and use the contents.

Learn what to do if you are unable to open JarFile on Windows 10 because you are experiencing difficulties or get an error message. Hope this article has provided you with all of the knowledge you need to execute JAR files on Windows or even convert them if that is what you want. If you are experiencing any additional problems, we have another article that can assist you if JAR files are not opening on Windows 10. Any further recommendations or queries can be left in the comments area below, and we’ll be sure to take a look at what you’ve got.

How to Run .JAR Files on Windows 10

In the event that you are unable to open.jar files on Windows 10, it is most likely due to one of the following issues: *The Java Run-Time Environment is not correctly configured to allow.jar files to be executed. *The Java Runtime Environment (JRE) is not being called properly by the Windows Registry. Fortunately, there are a handful of straightforward solutions to this problem. For the vast majority of individuals, when they attempt to open a.jar file, Windows will normally prompt them to choose which software they wish to use to launch the program.

In general, using the “Open With.” function in Windows 10 will not allow you to specify the complicated command that is necessary to open.jar files.

This means we must reassociate the.jar file with the Java binary, which is not difficult.

  1. Check that your Java Runtime Environment is up to date with the latest version. Navigate to your Java installation location, go into the /bin/ folder, right-click on Java.exe, and select “Run as Administrator” from the pop-up menu that appears
  2. Select ” Command Prompt (Administrator) ” or ” Powershell (Administrator) ” and type cmd
  3. Or press Windows+Xkeys and select ” Command Prompt (Administrator” or ” Powershell (Administrator)
  4. The following instructions should be entered into the prompt (change C:Program Filesetc with the location of your real Java installation folder, for example C:Program Files (x86)Javajre1.8.0 131binjava.exe):

Ftype jarfileterm=cmd /s /k “”C:Program FilesJavajre7binjava.exe” -jar “percent 1′′ percent *” -jar “C:Program FilesJavajre7binjava.exe” assoc.jar=jarfileterm Alternatively, if you wish the command prompt to remain open after the.jar file has been launched (for debugging purposes) ftype jarfileterm=cmd /s /k “”C:Program FilesJavajre7binjava.exe” -jar “percent 1′′ percent *” ftype jarfileterm=cmd /s /k “”C:Program FilesJavajre7binjava.exe” assoc.jar=jarfileterm Now try to start the.jar file you downloaded earlier.

In accordance with which of the preceding procedures you followed, the java executable should either start or start with a persistent command prompt behind it (which will fill up with Java calls from the app, useful for debugging purposes).

  1. Right-click on your Startbutton and type ” regedit ” into the search box
  2. Then click on it to open it. Expand theHKEY CLASSES ROOTfolder and scroll down until you locate the folders ” jar auto file ” and ” jarfileterm “
  3. Now close the HKEY CLASSES ROOTfolder and restart your computer. Add the following command to the jar auto fileShellOpenCommand path: You’ll see a key labeled ” Default ” on your keyboard. Right-click on ” Default ” and select ” Modify ” from the context menu
  4. Place the ftype command you entered earlier in the command prompt in the ” Value data ” box, so that it appears like the screenshot below, and then hit OK
  5. Do the same thing for the jarfileterm folder (expandjarfiletermShellOpenComand)
  6. Then do the same thing for the jarfileterm folder. Once you have finished using regedit, start your.jar file, which should now open properly.

How to Open JAR Files in Windows 10

A JAR file is an abbreviation for Java Archive file. It is used to bundle Java files and metadata into a single file that can be easily shared. With this article, you will learn how to open a JAR file in Windows 10, which is the most recent version available. We’ll go through what JAR files are and how to open them in the next sections. Additionally, while attempting to open a JAR file, you may experience problems. We’ve got you covered there, too, with our solutions for you.

What Is a JAR File?

JAR is an abbreviation for JavaAR chive. It is, as the name implies, a file that contains an archive of information. This indicates that it is a single file that contains many files that have been bundled together for reasons such as portability and reduced storage space. If you’re familiar with ZIP files, you’ll recognize that a JAR file is virtually identical to them. The distinction is that JAR files are programs that are intended to be utilized by the Java Runtime Environment, whereas.class files are class files.

Essentially, this is an unique meta-file that instructs the JAR on how to act and contains information about the contents included therein.

The Runtime Environment may then read and run the JAR file as a single request because it is contained within a single file.

Among other things, it may be a game, an application theme, or a browser plug-in.

How to Open JAR Files

Java Runtime Environment (JRE) must be installed before you can execute a JAR file (that is, run the actual application contained within it). You may already have it installed on your computer, but downloading it again from the official website will guarantee that you are running the most recent version available. After that, you should download a little utility known as Jarx to complete your task. This causes JAR files to function in the same way as regular applications on your computer. As a result, after Jarx has been installed, you may open a JAR file just like any other file.

  • To open the Command Prompt, press the Windows key + X together (Admin).
  • This can be done to determine what files are contained within the JAR file or to determine if the JAR file is not intended to be used as an executable file.
  • You can accomplish this using the built-in capabilities of Windows, but you can also utilize file extraction tools such as 7-Zip or WinRAR to complete the task.
  • You may also extract the JAR if you wish to utilize or analyze the individual files that are contained within it more thoroughly.
  • It is recommended that you use Archive Extractor since it is simple to use and, most importantly, it supports JAR files (not all online extractors do).
  • Open or expand a folder by double-clicking it; download a file by selecting it from the drop-down menu.

If your computer is having trouble recognizing an executable JAR file, you may right-click the file, selectRename, and then attach the.ZIPfile extension to the filename. This works because the file types are so intimately associated with one another.

How to Make JAR Files

What makes you so certain that you need to create a JAR file? Please keep in mind that they have a specific purpose: combining files in order to be utilized as a Java program. If that’s what you’re looking for, check out Oracle’s instructions on packaging applications in JAR files. Everything you need to know about how to generate, package, and sign a JAR file is included inside this document.

How to Fix Problems Opening JAR Files

When you attempt to open a JAR file, you may see an error, which is frequently caused by incompatibility or security settings.

Update the Java Runtime Environment

It is recommended that you always use the most recent version of the Java Runtime Environment. To find out what version of Java you’re running, go to the Start menu and put configuration java into the search box. Then choose the result. The Java Control Panel will appear on the screen. On the General tab, selectAbout and make sure that the version you’re running corresponds to the most recent version accessible straight from Oracle’s website by clicking the link. If you don’t have it, get it and install it.

JAR Opens in the Wrong Program

Windows may be unable to recognize the JAR file and may attempt to open it with a software that does not support the format. To fix this, right-click the file and select Open with from the context menu. There are various default programs from which to pick, and one of these may turn out to be the most appropriate. If this is not the case, clickChoose another app. If you want JAR files to open in the same program every time, you may modify the file associations and default programs in Windows 10’s settings.

  1. Go to Program FilesJava on your computer’s hard drive. Open the lone folder (nameddjre1.8.0 281 or something along those lines)
  2. Open the binfolder
  3. Run the java.exe program.

JAR Gives Security Error When Opening

Due to the fact that Java is considered a security concern, do not be shocked if you see a warning while opening a JAR file. To fix this, open the Start menu, enter configure java, and then choose the result from the list that appears. The Java Control Panel will appear on the screen. Then:

  1. Select theSecuritytab from the drop-down menu. Check that the Enable Java content for browsers and Web Start apps checkbox is selected. Increase the degree of security to Extreme
  2. If required, add the site to the list of exceptions. ClickOK

Java Isn’t Just for Windows

Hopefully, you now have a better understanding of what a JAR file is, how to open it, and how to handle any issues that may arise. While this article has concentrated on Windows, Java can be installed on a variety of other operating systems as well. The same is true for Ubuntu, where Java is valuable regardless of whether you’re writing in the language or utilizing an application.

Unable To Run .JAR Files in Windows 10 / 11 ? Here’s the Solution

A JAR file is based on the Java archive file format, and it may include a Java application as part of its contents. Although you can extract the.JAR files using a zip file extraction program such as 7zip, this will not allow you to launch a competitive Java application based on the.JAR files. Consequently, if you are experiencing difficulties opening a.jar file, you can attempt the solutions listed below.

Method 1 – Download and run jarfix

In this free software, you may restore jar files and allow you to execute files that were previously impossible to be opened by the operating system. 1. Simply go to this page and get the jarfix package. 2.Now, when you have downloaded it, you must install it. Now, give it another shot.

Method 2: By Creating a.bat File

Start by opening a notepad and typing the following text into it:java -jarsample.jar*Note –Replace whatever is the name of your.jarfile in the highlighted area of the text. 2.Save the file with whatever name you choose in the same place where your.jarfile is saved, followed by the.batextension, in the same folder as your.jarfile. For example, we renamed the file run.bat and set the Save as type to All Files in this example. To save your work, click on theSavebutton. Now, simply double-click on the run.batfile, and your.jarfile will be opened without any issues.

Method 3: By Downloading Java

Step 1: Go to Java.com and click on the Download Java button. Second, on the website’s download page, click on theDownloadbutton in red to begin downloading the Javasetup package. Step 3:Once the installation is complete, navigate to the directory where the.jarfile has been saved and double-click on it to launch the application. If the first technique does not work, try the second.

Method 4: Through Properties

The first step is to simply right-click on it and chooseProperties from the context menu that appears. 2nd step: In thePropertieswindow, select theChange button. Step 3: In the following box, select More apps from the drop-down menu. Step 4:Scroll down and select Look for another program on this computer from the list. Step 5: It leads you to the File Explorer, where you should click on the C driveshortcut and then complete the steps outlined below:

  • Then double-click onProgram files for the Intel processor
  • Double-click on Java
  • Double-click onjre1.8.0 251
  • Double-click onbin
  • And selectjavaw.

Using the double-click command on Javaw, you will be sent back to thePropertieswindow. Step 6: To submit your application, click onApply and then OK. Your.jar file should be open at this point. If the third approach does not work, try the first two methods again.

Method 5: Using Command Prompt

Start by clicking on the Start button on your desktop and typing Command Prompt into the search bar that appears. Run as administrator by right-clicking on the result and selectingRun as administrator. Step 2:In the Command Promptwindow, type the following command in the manner listed below and press Enter. ftype jarfile=”C:Program Files (x86)Javajre1.8.0 251binjavaw.exe ” -jar ” percent 1″ percent ** ftype jarfile=”C:Program Files (x86)Java Note – The path entered corresponds to the same path forjava that was shown in Method 2.

But if the problem continues, you can use the 4th option as a last resort.

If none of the techniques listed above work, try searching for jarfixprogram on Google and downloading it. This will immediately resolve the situation. Writing technical articles about Windows PCs and softwares is something I like doing.

How To Run .jar Files On Windows 10

JAR is an abbreviation for Java ARchive. JAR files contain the extension.jar, and they are based on the ZIP file format in which they are stored. A JAR file is a compressed archive containing Java classes. If you have a code snippet that you want to use in various projects, you may create a JAR file that contains the specific classes that you want to use in numerous places or projects and then distribute it. You won’t have to write the same code over and over again since you can just pick up the JAR file and put it to use instead of writing it from scratch.

Precisely, If you want to start an a.jar file, look for the command prompt and right-click on it.” Select “run as administrator” from the drop-down menu.

It is discussed in this post a number of various approaches that you may use to read and run JAR files on your Windows 10 computer.

Method 1: Opening jar File Using Notepad

Notepad should be open with the following content typed in it: –jar –java –jar (file name). jar In the place of (filename), type the name of the JAR file that you want to use. Right-click on the file name and select’save as’. The file should be saved with the extension ‘.bat’. Make sure that you save it in the same location as the JAR file you just downloaded. When you run this file, the jar file will also be opened in a new window. Using JavaRight-click on the jar file and select Open with. Select the ‘Properties’ option from the drop-down menu.

  • The “look for another app on this PC” option is located at the bottom of the screen.
  • Find and open the ‘java’ folder on your computer.
  • Locate and select the word ‘javaw’ from the recycle bin.
  • Click on ‘apply’ and then on ‘Ok’ to complete the process.

Method 2: Opening jar File Using Command Prompt

Enter ‘cmd’ or ‘command prompt’ in the search box at the bottom of your home screen and press Enter. “Run as administrator” may be selected by right-clicking on the command prompt. Give the command prompt the rights it needs to do certain tasks, such as making modifications to the system. Once the command prompt’s black UI appears, type the command listed below to bring up the command prompt: –ftype jarfile=”(File path)javaw.exe” –ftype jarfile=”(File path)javaw.exe” percent * jar “percent 1” per cent In this section, in place of (File path), copy and paste the path to the location where your JAR file is located.

You should be able to open and run your JAR file after typing this command, so press Enter when you have finished typing the command.

Method 3: If your jar file is in WinRAR format

When it comes to jar files, another difficulty that many customers have is that their jar files are in the format of WinRAR files, and when they try to access them, they are opened in WinRAR rather than the java format. In order to resolve this issue, the file must be converted from WinRAR format to real Java format. This problem is mostly caused by two factors: –

  • There is no Java development kit, often known as a JDK, installed on your Windows 10 computer. You have not made it the default application for opening your jar files
  • Hence, it is not the default software.

JDK vs. JRE: Which Is Better? Alternatively, if you do not have the java development kit loaded on your laptop but do have the java runtime environment or JRE, you can resolve this issue without having to install the java development kit first. Although installing and utilizing JDK is recommended due to the fact that it is more convenient and user-friendly, it is not required. It is important to understand that the JDK and the JRE are not interchangeable. The JDK contains everything that the JRE does, but in addition to all of the capabilities of the JRE, it also contains additional valuable tools such as compilers and debuggers.

Installing the Java Development Kit To install JDK, navigate to the download page and select the most recent version of JDK that matches to your system specs.

Now, follow the procedures outlined below to make your WinRAR file seem and behave like a real Java file, as well as to make it open with java as the default application.

Method 4

Open your file explorer and select the ‘view’ option from the drop-down menu. Navigate to the section that reads ‘options’ and choose the drop-down arrow. Select “Change folder and search options” from the drop-down menu. Select the ‘view’ tab from the drop-down menu that appears in the dialogue box. Scroll down the list until you reach the option “Hide extensions for recognized file types.” Uncheck the corresponding checkbox and then click on ‘apply’, followed by the ‘Ok’ button. After we’ve completed the actions outlined above, we’ll need to make JDK the default application that opens our files when we double-click or right-click them to initiate their opening.

Then select ‘pick another app’ from the drop-down menu.

If you go down to the bottom of the dialogue box, you’ll see a tick that reads, “Always use this app to open.jar files,” choose that option.

Even after converting your WinRAR file to a java file and configuring your default application to execute it, you may still experience problems when you double click on it.

If this happens, try one of the first three options listed in this post. After gaining all of this knowledge, you should never have any problems with JAR files again.

How to open or run a JAR file on Windows 11/10

JAR files are similar to EXE files, with the exception that they require the Java framework in order to operate. You may think of them like Windows EXE files, which you can double-click to start an application as needed. When you start an EXE file, it makes advantage of the Windows operating system support. Additionally, when you launch JAR files, you require the assistance of the Java Framework to open them. When we say “open JAR file,” we are not referring to opening the file in the same way that we would an archive file, but rather to running it.

What is Java executable JAR file?

Un compressed JAR file contains not only directories and source files, but it also has the capability of running as executable files. It is possible for such Java ARchive files to contain Java class files that will be executed when the JAR file is executed. While Archiver programs such as 7-Zipcan extract content from JAR files, doing so is meaningless since we need to run the files in the same way that we run EXE files.

How to run a JAR file in Windows 11/10

Because Java files cannot be executed on Windows by itself, you must first install theJava Framework, which is also known as Java in the public press. Having said that, Java files may be dependant on a certain version of the Java programming language. As a result, the procedures necessary to access JAR files on Windows 11/10 are as follows:

  1. Java must be downloaded and installed. Configure the system directory
  2. Execute the JAVA file
  3. Configure the Java file association
  4. Create a file association between the Java runtime and the file

1] Download and install Java Framework

Installing Java on your PC is required in order to run a JAR file on Windows. Navigate to the Java Download Page and complete the installation. The default setting will only install the most recent version. If your JAR file, on the other hand, requires a different version of Java, you may get it from this page. It is possible that an earlier version of Java is still in use and causing problems. As a result, if you are experiencing this issue, please sure you first uninstall the previous version.

Then you need install the most recent version.

2] Set System Path for Java

Following that, you must set the JAVA HOME variable. It ensures that any JAVA file you execute will be able to locate the essential libraries for the application to operate. Additionally, you may use the command line to echo the Java path to see whether or not it is accurate.

3] Run a Java or JAR file

When you double-click on the JAR file, it will automatically run in the same way that EXE files do when they are executed. If there is an issue with the version, the file should notify you of the problem. A JAR file that isn’t operating on its own can be executed by using the Java JDK (Java Development Kit). Open a Command Prompt and type java -jar name of jar file.jar into the window that appears. It will run the JAR file on its own initiative.

4] Set the Java or JAR file association

It is necessary to associate a file with the Java runtime before proceeding to the next step. It will ensure that every time you run, you will not be prompted to choose an application that can execute it on your computer.

  1. Hold down the Shift key and right-click on the file, then pick Open with option
  2. Make the selection ‘Choose another app.’ You may need to scroll down and then click on More Apps if the Java(TM) Platform SE binary is not included in your list. Then select Choose an application from your computer. ‘Java(TM) Platform SE binaries’ should appear in this context menu, but you should not pick it. Look for a file that may be used to launch the JAVA or JAR file that is located in the directory that we indicated previously. Make sure to tick the option that reads, “Utilize this software on a regular basis.”

All subsequent JAR files will automatically open using the Java run time library when this is completed.

All of these files should have the Java icon displayed next to them.

How run Java JAR from command line?

In order to start the a.jar file, you’ll need to utilize the java command. java -jarfinename.jar java -jarfinename.jar It is possible to resolve the problem of not having Java installed by installing thedefault-jrepackage. We hope you found these instructions straightforward to follow and that they were helpful in opening or running a Java file on Windows 11/10.

How to Open a JAR File on Windows

On rare occasions, you will encounter apps or games released as.jar files rather of the more common.exe file. It is not possible to execute an application by just double-clicking on a JAR file. So, how do you go about opening a JAR file? Java used to be a popular coding language for creating freeware games and programs, and it continues to be so today. Even today, many freeware applications are delivered as.jar files, which are incompatible with Windows’ native support. This post will show you how to access JAR files on your computer using several methods.

What Is a JAR File?

Java was utilized by internet browsers to provide a more dynamic surfing experience. Java was used to code the games and other interactive applets, which allowed them to run on any platform. However, there was a minor snag in the plan. It took many HTTP requests to get all of the components necessary for the applet to function properly, which increased the load time of the applet. A better method would be to consolidate all of the files into a single file that Java could access in order to run the program as a single unit.

JAR, which was inspired by WinZip, is a file archive format used by Java to store anything from multimedia files to code, and it is accessible to Java applets and other Java applications.

Install Java on Your PC

For the most part, installing the Java Runtime Environment (JRE) on your computer is the most easy method of opening a JAR file. Not only does this provide you with the ability to open.jar files, but it also allows your system to run Java-based applications.

  1. To obtain the most recent Java Runtime Environment (JRE), visit Oracle’s official download page.
  1. Scroll down to discover the installation package that corresponds to your operating system version. There are installers available both online and offline. The online setup will simply download the necessary files while the installation is taking place, whereas the offline setup will download all of the necessary files beforehand and then begin the installation process.
  1. To begin the installation of JRE on your computer, run the downloaded file from your computer’s hard drive. Accept the licensing agreement in order to begin the setup process. Usually, the installer will automatically remove earlier versions of JRE, but if necessary, you may remove them manually if you so want.
  1. An installed Java application, including JAR files, can be used on your computer once the installation is complete.

It’s important to note that this just permits your computer to open JAR files via the manner described below; it does not associate the.jar extension with the file, which means that if you try to double-click a JAR file, Windows will still not know what to do with the file. Learn how to open a JAR file after installing the Java Runtime Environment (JRE) in the next section.

Open From Command Prompt

Please understand that this is not a new approach in any way. You will still need to have Java installed on your computer in order to access JAR files from the command prompt, so this step must be performed first. The command prompt may be used to open JAR files once you’ve completed the installation of Java on your computer following the procedure described in the previous section.

  1. An administrator is prompted with the OpenCommand command. The application may be found by typing cmdin the search bar
  1. You can use the commandjava -jar C:pathtofile.jar to open the file in question, where “pathtofile” is the path to the file in question. In order to make things simpler, you may copy the file to the C drive itself, which will allow you to input only the file name.
  1. When the command is executed, Windows will utilize the Java Runtime Environment (JRE) to interpret the JAR file. You should now be able to see the Java application in action.

Because JAR files are not executable Java files, you’ll have to go through all of these procedures every time you start a JAR file unless the program you want is provided as such.

Extract as an Archive

Files in the JAR format are archived data files with a catchy moniker. They are intended for Java programs, however the jar file is just a package that contains all of the JAR files compressed and archived in one place, allowing you to extract JAR files using any leading file extraction tool, such as WinRAR or 7-Zip. This will allow you to view the contents of the package, however you will still require the Java Runtime Environment (JRE) if you wish to launch the program.

  1. Installing 7-Zip on your PC is as simple as running the.exe file you downloaded.
  1. Make your way to the directory that contains the JAR file that you want to extract
  1. Right-click on the file and pick 7-Zip from the context menu
  2. Then select Extract All.
  1. The JAR file will be extracted into the directory where it was originally located.

What is the Best Method To Open a JAR File on Windows 10?

JAR files are Java programs that are compressed into a single file and distributed through the Internet. It is necessary to have the Java Runtime Environment installed on your computer in order to use them. Because the Java Runtime Environment (JRE) is free to download, this is the most straightforward method of getting.jar files to function on your Windows machine. When it comes to seeing the contents of a JAR archive without actually running it, you can always utilize a file extraction tool to accomplish your goal.

How to Run JAR Files on Windows 10

A jar file is an abbreviation for aJ avaAR chive file, and it is used to store Java applications (including Java class files, metadata, and resources). Because it is a package file format (similar to the.zip file format), a jar file may be used to bundle together a number of other files in order to increase mobility and reduce the amount of space that these files take up on the hard drive. As a result, jar files are incredibly adaptable, and they may be used to hold anything from a game to an application to a browser plugin, among other things.

Some are intended to be run/executed in the same way that.exe files are, while others are intended to be extracted/unpacked in the same way that.zip files are.

When a.exe file is double-clicked, it runs a program or application with the assistance of the Windows operating system.

Many users, however, encounter difficulties while attempting to run or execute jar files on Windows 10.

Why won’t jar files run?

A Jar file has a manifest, which effectively instructs the file on how to act while also including information on the other files contained within the jar file’s contents. In addition, a jar file contains class files that contain the Java code for the executable application that is included within it.

It is feasible for Java Runtime Environment to execute several jar files at the same time by using both of these files in conjunction with other media files. When attempting to launch a jar file, users may get one of the two problems listed above.

  • Jar files cannot be executed because the Java Run-Time Environment has not been correctly configured. The JRE (Java Runtime Environment) is not being called correctly by the Windows Registry.

First, when the user is using an old version of Java on his or her own computer, the problem occurs. Second, when the jar files are not correctly connected with the Java binary, the error occurs. In addition, when a user double-clicks on a jar file, a command prompt window appears for a split-second before disappearing, leaving the user bemused and frustrated. Fortunately, fixing these two issues as well as launching a jar file is a straightforward process.

How to Run JAR Files on Windows 10

As previously stated, in order to launch the application/code contained within a jar file, you must have the Java Runtime Environment installed. Follow the procedures outlined below to determine what version of Java is currently installed on your personal computer and how to upgrade to the most recent version: Open Command Prompt as Administrator by using any of the techniques listed below to get started. a. To open the power user menu, use the Windows key + X or right-click on the start button on your keyboard.

  8. Follow the on-screen steps to complete the installation of the most recent version of Java.
  9. You should first try completely deleting the old version of java using the official Java Removal Tooland then conducting a fresh installation if you are experiencing problems with the update.

Method 1: Using ‘Open With…’

First, we manually open the jar file with the Java Runtime Environment, which is the first way. To get the same result, follow the methods outlined below. 1. Launch the file explorer (Windows key + E), navigate to the jar file you want to execute/open, and choose it from the context menu. 2. 2. Select Open with from the file options/context menu that appears after that. 3. Go through the list of apps and try to identify the Java(TM) Platform SE binary by searching for it in the search bar. It is quite possible that you will not be able to locate it in the list of programs.

Select another application by clicking on Choose another application.

Go through the list once again, and if you don’t see the program you’re looking for, click on “More Apps.” Look for another program on this computer in order to manually locate the application.

It should be located under C:Program FilesJavajre1.8.0 221bin for most people, however if you can not find it there, try traveling down the following path: C:Program Files (x86)Javajre1.8.0 221bin7 is the location of the Java executable. Finally, type java.exe into the search box and hit enter.

Method 2: Run JAR files using the Command Prompt

Java Archive files (.jar) may also be executed using the Windows 10 command prompt interface. The procedure just requires the execution of a single command line and is straightforward to complete. 1.Open Command Prompt as an administrator by using any of the techniques described above. When the command prompt window appears, use the command cd to return to the directory’s root directory. 2. 3. Now, enter the following command on your computer: Enter the command java -jar sample.jar and press the enter key.

Alternatively, you may skip the second step and just replace sample.jar with the full path of the jar file you want to use instead.

Method 3: Using Third-Party Applications

There are a variety of third-party programs that allow you to run or execute jar files on Windows 10. These are similar to the applications available for everything else. Jarx is one of the most well-known jar executor tools available on the internet these days. Go to the official website for more information. Jarx – The JAR executer and download the software package by selecting ‘Jarx-1.2-installer.exe’ from the list of available options. Jarx may be installed by locating the downloaded file and double-clicking it.

  • To execute jar files on your personal computer, just double-click on the jar file or right-click and pick open from the context menu.
  • If you want to launch jar files, follow the same steps that we explained for Jarx.
  • As previously stated, not all jar files are intended or planned to be used as an executable file.
  • We can determine if a jar file is executable or not by simply unpackaging/extracting it from its packing.
  • One may either utilize the built-in extraction tool in Windows or seek assistance from one of the many file extraction tools that are accessible on the internet to accomplish the job for them.
  • To extract a file using Windows’ built-in extracting tool, just right-click on the jar file and pick one of the’Extract.’options from the context menu.

For a third-party program to extract a file from its original location, first visit the application’s website and download the installation file. Once you have completed the installation of the program, open the jar file in the application to view the information it contains.

Fix Unable to Open JAR Files on Windows 10

If you were unable to launch the jar files using any of the ways described above, you should attempt the following solution: 1.

Solution 1: Updating Registry Editor

Open File Explorer (Windows Key + E) and browse to the bin folder within the java installation folder. 2. Because it is installed on many disk partitions, the folder location differs from one partition to another. However, for the majority of users, the folder may be located on the C drive, under the Program Files or Program Files (x86) directory (x86). 2. Locate java.exe in the bin folder and right-click on it to bring up the Properties window. Select theCompatibilitytab and check the box next to “Run this software as an administrator.” To quit, click on Apply, followed by Ok to close the window.

For a straightforward launch of the jar file, simply type the following instructions and press Enter: ftype jarfileterm=cmd /s /k “”C:Program Files(x86)Javajre1.8.0 221binjava.exe” ftype jarfileterm=cmd /s /k “”C:Program Files(x86)Javajre1.8.0 221bin” -jar ” percent 1′′ percent *”assoc.jar=jarfileterm6″ -jar ” percent 1′′ percent *”assoc.jar=jarfileterm6″ To debug a jar file and keep the command prompt window active during debugging, execute the following command into the command prompt window after launching a jar file.

  1. ftype jarfileterm=cmd /s /k “”C:Program Files(x86)Javajre1.8.0 221binjava.exe” ftype jarfileterm=cmd /s /k “”C:Program Files(x86)Javajre1.8.0 221bin” -jar “percent 1′′ percent *” percent 1″ assoc.jar=jarfileterm Now that you’ve done that, try to open the jar file.
  2. We strongly encourage you to proceed with great caution while following the instructions provided below, since the Registry Editor is a powerful tool that should not be tampered with.
  3. In the left-hand panel, choose HKEY CLASSES ROOT and then click on the arrow or double click on it to expand it.
  4. Select the folderjarfile from the drop-down list (some users may be able to locate the foldersjar auto file andjarfiletermininstead of the folderjarfile).
  5. Open the jar file by double-clicking on it to begin.
  6. Navigate to the jarfileshellopencommand directory.
  7. To change the key, either right-click on it and select Modify or just double-click on it.
  8. Paste thefftypecommand that we typed earlier in the command prompt window into the Value Data label of the next pop-up box.

7. Double-check your work to ensure it is right, then click OK. Remember to perform the procedure for both folders (jar auto filejarfileterm and jar auto filejarfileterm, if you have them) and throughout the whole process. Eighth and last step: quit the registry editor and try to run the jar file.

Solution 2: Change Java Security Settings

Another issue that arises frequently with Java is the security risk. When attempting to launch a jar file, a warning message stating danger is frequently displayed. It is merely a matter of changing the security settings to address this issue. 1. To launch the Configure Java window, click on the Start button or use the Windows Key + S key combination and search for Configure Java. 2. Navigate to the Security tab by selecting it from the drop-down menu. 3. Double-check that the checkbox next to “Enable Java content for browser and Web Start apps” is checked.

Easy Ways To Open Jar File in Windows 10

What Is a Jar File and How Do I Open It? JAR is an abbreviation for Java Archive. A JAR file is a compressed archive that stores picture files, audio files, directories, and class files in compressed formats. This implies that a single JAR file can include a large number of additional files. It appears that JAR files are comparable to ZIP files in this regard. Despite the fact that they both appear to be the same, they are each unique in their own way. It is their respective functions that they execute.

JAR files are Java-specific manifest files that are compressed using the ZIP compression technique.

JAR files are simply a manifest that instructs JAR on how to retain and contain the information.

It is meant to execute other software, including JAR files, which is why it is referred to as the Java runtime environment (JRE).

How To Run Jar Files In Your Computer:

In this part, we will demonstrate how you may run the JAR files on your computer if you need to do so for a variety of reasons. When a JAR file does not open on your computer, one possible technical explanation is that you do not have the Java Runtime Environment installed on your computer. You can execute the JAR file by using the Java Runtime Environment, and you can see the files included in the JAR files by using any decompressing application that is compatible with the Java Runtime Environment.

The steps to take for both of your prospective choices are outlined in the next section.

Procedure 1: Running Jar Files

It is essential that you check that the Java Runtime Environment is installed on your computer before you attempt to launch the JAR file. In the event that you do not already have this application installed on your computer, you must obtain the most recent Java Runtime Environment from the following URL. Once you have completed the download and installation of the Java Runtime Environment, double-click on the JAR file to begin the process of running it. You must right click on the JAR file and select “open with” from the list of programs.

By double clicking on any JAR file, the Java Runtime Environment should always open the JAR file by default, regardless of whether or not the file is a JAR file.

Procedure 2: Decompressing the Jar File

The process of decompressing a JAR file is similar to that of opening a ZIP file. It is a non-executable process in which you can only read the contents of the JAR file. It is not recommended for use. There are numerous other pieces of software that may be used to decompress a JAR file, including “WinRAR,” “7-ZIP,” and “JarX,” and you can get any of them on the internet. Following the installation of a decompression application on your computer, you may easily access the JAR file by following the procedures outlined below.

  1. STEP 2: To open the compressed Jar file using WinRAR, double-click on it.
  2. To open the JAR file after it has been extracted, double click on it to activate it.
  3. If you have a JAR file that you are unable to open, you can rename the file type to “ZIP” and then open the ZIP file using the WinRAR or any other extraction application to open it.
  4. Conclusion: Opening a JAR file is not a difficult task if you know where to look for the appropriate chord.
  5. The JAR file may then be executed with relative ease.
  6. But there are other difficulties that might arise with JAR files, such as the fact that the JAR file will not open once you double click on it or for a variety of other reasons.
