  • The Unable to access the JAR file is a standard error when you don’t have compatible software to open it.
  • Some users reported that using stable file openers fixed the issue for them.
  • You can also fix this issue by uninstalling and downloading the latest version of Java.

unable to access jarfile

Java browser plug-ins might have gone out of fashion, but many programs run off Java. For example, you can open Java programs with JarFiles, among other software for opening JAR files.

However, some Java software users can’t always open JAR programs with the Unable to access JarFile error message popping up. This guide will show you some practical ways to get past this error message.

Why does it say unable to access jar?

The inability to access JarFile on Minecraft or Forge can be caused by mistakes on your path or issues with the software. Below are some of the prevalent causes:

  • Outdated Java version: If your Java version is obsolete, you cannot access JarFile using the docker container. You need to update Java to the latest version.
  • Wrong default program: Sometimes, this issue might be because you have not set the default program to open the JarFiles. Choosing Java as the default app for opening JAR files should fix this.
  • Issues with the JAR file path: If the path to your jar file is incorrect, you can get this error. The solution here is to ensure the path is correct.

How can I fix the unable to access JarFile error?

Before proceeding to the fixes in this guide, try the preliminary troubleshooting steps below:

How we test, review and rate?

We have worked for the past 6 months on building a new review system on how we produce content. Using it, we have subsequently redone most of our articles to provide actual hands-on expertise on the guides we made.

For more details you can read how we test, review, and rate at WindowsReport.

  • Add .jar extension to the JAR file name
  • Beware of spaces in the JAR file path
  • Add quotes to the JAR file path if it contains space
  • Move the JAR file to another folder
  • Use a file opener software

If the fixes above fail to solve the issue, you can now move to the fixes below:

1. Update your Java version

  1. Press the Windows key + R, type appwiz.cpl, and click OK.
    appwiz unable to access jarfile
  2. Right-click the Java app and select the Uninstall option.
    uninstall
  3. Now, go to the official website to download the latest version of the Java app.

A broken or outdated app can cause the unable to access the JarFile issue. Downloading the latest version of the app should fix the problem.

2. Select Java as the default program for JarFiles

  1. Open File Explorer and the folder that includes your JAR file.
  2. Right-click the file and select Open with, and then Choose another app.
    choose another
  3. Select Java if it’s listed among the default programs.
  4. If Java isn’t listed among the programs, select the Look for another app on this PC option.
    look for unable to access jarfile
  5. Then browse to the Java bin folder, select  Java and press the Open button.

JAR file error messages usually pop up when Java isn’t configured as the default software for a JAR file. This can be the cause of the unable to access JarFile.

Setting Java as the default program should fix the issue here.

If you have recently tried to open a JAR package file, only to receive the error, “unable to access Jarfile,” this simply means that your computer either doesn’t have the right software to open the file, or you have the wrong file path. Other common reasons for getting this error is if you have an outdated version of Java, your computer is infected with malware, or the default program for opening your JAR files isn’t set correctly. Before we jump into the solutions for this, let’s take a look at what JAR is.

Unable to access jarfile error message on Windows

Understanding JAR Package Files

Java Archive or JAR is a package file format based on ZIP architecture. It is used to group together multiple Java class files, their metadata, and any resources these files need to run into one single package. The purpose of doing this is to then distribute the grouped files as needed for the running of applications and programs. In order to run the executable file in a JAR package, you must have the latest Java Run-Time Environment installed.

Jarfile Examples.

If you are getting the error, “unable to access Jarfile” it means that you are encountering one of the following problems:

  • Your system has malware that is either preventing the Jarfile package to open.
  • The Jarfile package is corrupted from malware.
  • You do not have the latest Java Run-Time Environment installed.
  • The default program for accessing JAR files isn’t set.
  • The file path for the executable Jarfile package is incorrect.

The “unable to access Jarfile” error is quite a common one since there are many popular programs that use Java as their programming language. For instance, Netflix uses it along with Python for applications in its back-end, while Spotify uses it to stabilize data transfer, and Minecraft uses it for its launcher. Other popular programs and services that use Java include: Uber, Amazon, LinkedIn, Google, and Android OS.

1. Update Your Java to the Latest Version

The most likely reason that you are getting the, “unable to access Jarfile” error is due to an outdated version of Java. Unfortunately, outdated versions of Java Run-Time Environment are prone to security risks and loopholes, so keeping it updated is highly recommended regardless of whether you are getting the above error.

  1. In your computer’s search menu, type in “Control Panel”.
  2. In the control panel window, choose “uninstall a program” under programs.
Image of Windows 10 control panel and the uninstall a program option.
  1. In the list of programs, scroll until you see Java. Or use the search program box in the top right-hand corner of the window.
  2. Take a look at the version number and see if it matches the latest release.
  3. If it doesn’t, uninstall the program by right-clicking on it.
Image of how to uninstall Java and see the version number in the uninstall program function on Windows 10.
  1. Choose “yes” when prompted.
  2. From the official Java website, download the latest version.
  3. Once downloaded, use the setup wizard to install Java.

Now, re-try opening your JAR package to see if the problem is fixed.

2. Make Java the Default Program for Opening JAR Packages

If you are still getting the “unable to access Jarfile” error after updating your Java Run-Time Environment to the latest version, then you may not have Java set as the default program to use for opening JAR packages.

  1. In your computer’s taskbar, open File Explorer.
  2. Find the folder that contains your JAR package.
  3. Right-click on the folder and choose “open,” and then Java.
  4. If Java is not listed, select “choose another app”.
Use Java to open your Jarfile package.
  1. In the window that pops up, choose Java from the list. If it is not there, choose the “look for another app on this PC” option.
  2. Browse your computer for Java and find the program. Select it and hit the “open” option.
  3. A prompt window may open. If it does, choose “okay” and “open”.
  4. Double-click on your JAR package executable to open.

When browsing for Java on your computer in step 6, the most common place for it to be is in Program Files (x86)/Java/Java <Version>/Bin/Java.exe. Keep in mind that Java is usually installed to the default hard drive disk where your operating system is, unless you do a custom installation path. So, keep this in mind when trying to find Java on your computer.

3. Set Java as a Default Association Permanently

If you use a lot of programs or applications that use the Java Run-Time Environment, it is recommended that you set Java as a default association permanently in your computer, so that any JAR packages or files are automatically opened by Java.

  1. Press the Windows key and “I” on your keyboard to open Settings. Alternatively, type “settings” into your computer’s search menu.
  2. Click into the “apps” option in the Settings window.
Apps in Settings Window on Windows 10
  1. Choose “default apps” in the left-hand sidebar.
  2. Scroll until you see, “choose default apps by file type” and click it.
  3. Now, look for .jar in the list and click on “Choose a default” next to it.
  4. Find the Java Platform Program (Java Run-Time Environment) on your computer.
  5. Save the changes and exit.
Windows 10 Settings - Apps, Set Java as a Default Program to Use

Now restart your computer for the changes to take effect and see if you can open your JAR package without the, “unable to access Jarfile” error.

4. Check for Malware to Eliminate Infections Causing Trouble

If you are still getting the “unable to access Jarfile” error, it may be from malicious malware. A virus can easily exploit your registry and modify it to make JAR packages unusable. It is highly recommended that you run a thorough scan of your entire computer to look for malware. If you find some, remove it and uninstall Java. Repeat fix 1 in this list to reinstall.

5. Configure Hidden Files/Folders/Drives to Show

While not as common, sometimes hidden files, folders, and drives can cause the “unable to access Jarfile” error.

  1. In your computer’s taskbar, open File Explorer.
  2. At the top of the window, click on the “View tab”.
Click View - Then Options.
  1. Now click on the “Options” button to the far right.
  2. In the new window that opens, click on the “View tab” again.
  3. In the list, choose the “Show hidden files, folders, and drives” option.
  4. Hit Apply and then hit OK.
Checkmark the Show Hidden Files, Folders, and Drives Option.

6. Repair Your Java Programs with Jarfix.

If you are using programs that launch with Java and they are not responding to you, no matter how many times you try to open the application, then it may be time to repair your JAR associations. To do this, simply download Jarfix, a lightweight program that fixes hijacked JAR associations, and run it.

What Jarfix looks like.

7. Check the Documentation If You Are a Developer

If you are working in Java as a developer and come across the “unable to access Jarfile” error, it is likely that there is a minor mistake within the coding. It is recommended that you go back through and re-read to make sure that you have the right file path and the correct parameters for the code to work. Depending on what utility you are using to open and run your JAR packages, you may need to go back through and re-read the documentation on how to get it functioning properly.

Solution 2: Change The Open With Option

Some users have reported that after a recent update to their Windows, the default app associated with the .JAR file format changed to some other apps installed on their device. This can also be one of the reasons that you see the Unable to access error for the .jar files on your computer.

This can be easily solved, as all you need to do is change the default app associated with the file using the right-click context menu. Here are the simple steps that you need to follow:

  1. First, navigate to the directory where you have saved the .JAR package using file explorer.
  2. Right-click on the .jar package to reveal the context menu.
  3. Hover over Open with > to reveal additional settings.
  4. Here you should see your Java application on the list.
    Click on it to open the file with your java application.

open_with_java_platform_binary

If you wish to permanently change the application associated with jar file packages to the Java app installed on your computer, follow these steps:

  1. Right-click again on the .JAR file to reveal the context menu.
  2. Click on Properties from the menu.
  3. Under the General tab, click on the Change… button next to the Opens with section.

Now check if changing the default file association solved the error for you.

Solution 3: Check The Documentation For Wrong File Paths

If you are a developer facing this problem while running JAR files, you might have some additional work to do in order to solve this issue. This error is really troublesome, as you will need to crosscheck the app code that is presenting you the error.

To find out what is causing this error, you need to read the utility documentation provided of the package that shows you the error. There is a chance that there is an incorrect parameter pointing to some invalid location. If the file path is wrong, there is a chance that you may be presented with this error.

You can use coding websites like Stack Overflow to produce a demo of the function that you are trying to run. Scrub through the code to identify the problem and fix it to solve the error.

Solution 4: Update Or Reinstall The Java Application

If the solutions above failed to help solve your jarfile error, the problem might be with the java app itself. If you are not running the latest version of the Java platform, there is a chance that the .JAR package will fail to recognize the java app completely.

Update your java application. Although Java updates are usually installed automatically, sometimes you may have to manually update the app in order to solve the errors associated with the app.

If updating the app did not help you, you will need to reinstall the application completely for java to run properly. You can uninstall the application from either the control panel or use a third-party batch uninstaller (like the ones from this list) to remove residual files as well.

Next, visit the Java website. Download the latest version of the Java application on your computer and install the same.

download_java

With the latest version installed, check if the error persists. The unable to access jarfile error should now be resolved.

I had encountered this issue when I had run my Jar file as

java -jar TestJar

instead of

java -jar TestJar.jar

Missing the extension .jar also causes this issue.

[Possibly Windows only]

Beware of spaces in the path, even when your jar is in the current working directory. For example, for me this was failing:

java -jar myjar.jar

I was able to fix this by givng the full, quoted path to the jar:

java -jar "%~dp0\myjar.jar" 

Credit goes to this answer for setting me on the right path….

I had this issue under CygWin in Windows. I have read elsewhere that Java does not understand the CygWin paths (/cygdrive/c/some/dir instead of C:\some\dir) — so I used a relative path instead: ../../some/dir/sbt-launch.jar.

I had the same issue when trying to launch the jar file. The path contained a space, so I had to place quotes around. Instead of:

java -jar C:\Path to File\myJar.jar

i had to write

java -jar "C:\Path to File\myJar.jar"

Just came across the same problem trying to make a bad USB…

I tried to run this command in admin cmd

java -jar c:\fw\ducky\duckencode.jar -I c:\fw\ducky\HelloWorld.txt  -o c:\fw\ducky\inject.bin

But got this error:

Error: unable to access jarfile c:\fw\ducky\duckencode.jar

Solution

1st step

Right click the jarfile in question. Click properties.
Click the unblock tab in bottom right corner.
The file was blocked, because it was downloaded and not created on my PC.

2nd step

In the cmd I changed the directory to where the jar file is located.

cd C:\fw\ducky\

Then I typed dir and saw the file was named duckencode.jar.jar

So in cmd I changed the original command to reference the file with .jar.jar

java -jar c:\fw\ducky\duckencode.jar.jar -I c:\fw\ducky\HelloWorld.txt  -o c:\fw\ducky\inject.bin

That command executed without error messages and the inject.bin I was trying to create was now located in the directory.

Hope this helps.

None of the provided answers worked for me on macOS 11 Big Sur. The problem turned out to be that programs require special permission to access the Desktop, Documents, and Downloads folders, and Java breaks both the exception for directly opened files and the permission request popup.

Fixes:

  • Move the .jar into a folder that isn’t (and isn’t under) Documents, Desktop, or Downloads.
  • Manually grant the permission. Go to System Preferences → Security and Privacy → Privacy → Files and Folders → java, and check the appropriate folders.

If you are using OSX, downloaded files are tagged with a security flag that prevents unsigned applications from running.

to check this you can view extended attributes on the file

$ ls -l@
-rw-r--r--@ 1 dave  staff  17663235 13 Oct 11:08 server-0.28.2-java8.jar
com.apple.metadata:kMDItemWhereFroms         619
com.apple.quarantine          68

You can then clear the attributes with

xattr -c file.jar

I had a similar problem and I even tried running my CMD with administrator rights, but it did not solve the problem.

The basic thing is to make sure to change the Directory in cmd to the current directory where your jar file is.

Do the following steps:

  1. Copy jar file to Desktop.

  2. Run CMD

  3. Type command cd desktop

  4. Then type java -jar filename.jar

This should work.


Edit: From JDK-11 onwards ( JEP 330: Launch Single-File Source-Code Programs )

Since Java 11, java command line tool has been able to run a single-file source-code directly. e.g.

java filename.java

For me it happens if you use native Polish chars in foldername that is in the PATH.
So maybe using untypical chars was the reason of the problem.

My particular issue was caused because I was working with directories that involved symbolic links (shortcuts). Consequently, trying java -jar ../../myJar.jar didn’t work because I wasn’t where I thought I was.

Disregarding relative file paths fixed it right up.

In my case the suggested file name to be used was jarFile*.jar in the command line. The file in the folder was jarFile-1.2.3.jar . So I renamed the file to jarFile. Then I used jarFile.jar instead of jarFile*.jar and then the problem got resolved

It can happen on a windows machine when you have spaces in the names of the folder. The solution would be to enter the path between » «.
For example:

java -jar c:\my folder\x.jar    --> 
java -jar "c:\my folder\x.jar"

To avoid any permission issues, try to run it as administrator. This worked for me on Win10.

I know this thread is years ago and issue was fixed too. But I hope this would helps someone else in future since I’ve encountered some similar issues while I tried to install Oracle WebLogic 12c and Oracle OFR in which its installer is in .jar format. For mine case, it was either didn’t wrap the JDK directory in quotes or simply typo.

Run Command Prompt as administrator and execute the command in this format. Double check the sentence if there is typo.

"C:\Program Files\Java\jdk1.xxxxx\bin\java" -jar C:\Users\xxx\Downloads\xxx.jar

If it shows something like JRE 1.xxx is not a valid JDK Java Home, make sure the System variables for JAVA_HOME in Environment Variables is pointing to the correct JDK directory. JDK 1.8 or above is recommended (2018).

A useful thread here, you may refer it: Why its showing your JDK c:program files\java\jre7 is not a valid JDK while instaling weblogic server?

For me it happen because i run it with default java version (7) and not with compiled java version (8) used to create this jar.

So i used:

%Java8_64%\bin\java -jar myjar.jar

Instead of java 7 version:

java -jar myjar.jar

I had a similar problem where TextMate or something replaced the double quotes with the unicode double quotes.

Changing my SELENIUM_SERVER_JAR from the unicode double quotes to regular double quotes and that solved my problem.

this is because you are looking for the file in the wrong path
1. look for the path of the folder where you placed the file
2. change the directory cd in cmd use the right path

I use NetBeans and had the same issue. After I ran build and clean project my program was executable. The Java documentation says that the build/clean command is for rebuilding the project from scratch basically and removing any past compiles. I hope this helps. Also, I’d read the documentation. Oracle has NetBeans and Java learning trails. Very helpful. Good luck!

Maybe you have specified the wrong version of your jar.

I finally pasted my jar file into the same folder as my JDK so I didn’t have to include the paths. I also had to open the command prompt as an admin.

  1. Right click Command Prompt and «Run as administrator»
  2. Navigate to the directory where you saved your jdk to
  3. In the command prompt type: java.exe -jar <jar file name>.jar

Keep the file in same directory where you are extracting it. That worked for me.

This is permission issue, see if the directory is under your User.
That’s why is working in another folder!

Rename the jar file and try

Explanation :
yes, I know there are many answers still I want to add one point here which I faced.

I built the jar and I moved it into the server where I deploy (This is the normal process)
here the file name which I moved already existed in the server, here the file will override obviously right. In this case, I faced this issue.
maybe at the time of overriding there can be a permission copy issue.

Hope this will help someone.

If you are on WSL (Windows Subsystem for Linux), and following a guide which say, says this:

java -Djava.library.path=./DynamoDBLocal_lib -jar DynamoDBLocal.jar -sharedDb

You actually need to specify the full path, even though you’ve provided it in the java.library.path part.

java -Djava.library.path=/mnt/c/dynamodb_local/DynamoDBLocal_lib -jar /mnt/c/dynamodb_local/DynamoDBLocal.jar -sharedDb

Have you tried to run it under administrator privoleges?
meaning, running the command in «Run As» and then select administrator with proper admin credentials

worked for me

I was trying this:

After giving the file read, write, execute priviledges:

chmod 777 java-repl.jar

alias jr="java -jar $HOME/Dev/java-repl/java-repl.jar"

Unable to access bla bla…, this was on Mac OS though

So I tried this:

alias jr="cd $HOME/Dev/java-repl/ && java -jar java-repl.jar"
