Jarfix

If you double-click a jar file and your Java application does not launch, your.jar association has been hijacked. You can use Jarfix to resolve the issue. 

The root cause of the issue described above is that an application has stolen the.jar association. If you install the Java Runtime Environment for the first time, javaw.exe is assigned the correct file type "jar". "jar" stands for "java archive," and the correct application to run a.jar is javaw.exe. However, on Windows, any software can steal a file type at any moment, even if it is already linked to a Jarfix application. 

Because a jar is stored in.zip format, many zip/unzip tools choose to do so. When you double-click on a.jar, your pack application opens the file rather than running the program because it ignores the meta information that is also stored in a.jar. The low-priority report 4912211 "add mechanism to restore hijacked.jar and.jnlp file extensions" is in the Oracle bug database, but it has been classified as "Closed, Will Not Fix". 

If you are using a free OpenJDK that does not include an installer, you may miss the file connection with.jar. When this problem arises, reinstall the Java Runtime Environment or manually repair the Windows Registry. 

You can easily resolve this issue with the simple but dependable jarfix.exe application. Simply double-click it to reactivate the.jar association with javaw.exe.
