Where are the downloaded jars in a Java Web Start Application?

Question

I have an Eclipse application loaded using Web Start.

I know that the Eclipse Plugins must be stored somewhere as jars. In which location are they stored when such an application is downloaded using Java Web Start?

I am expecting the JAR files to be somewhere on the user directory, but I haven't been able to track them yet.

Thanks!

Answer 1

I believe that if you have Java set to keep temporary files, they're stored under the directory you have specified for that, though not as plain jars. From what I can tell, if you don't have that option set, they're stored in your Temp folder (in Windows, anyway) in files called jar_cache*.tmp, where * is a long number.

Hi,

Check the "Temporary Internet Files" section of Java control panel --> General tab. It would tell you the place where you have saved the application.

The default path is.. (On windows) %appdata%\Sun\Java\Deployment\cache

The "View" button in the same section would provide you a quick way to launch the applications that are saved on your system.

Application is saved as jar (though without the .jar as extension) inside one of folder of cache. You can open the files using 7-zip or some other extraction software.
