The easiest way is by directly editing the file associations in the registry. Open an elevated regedit, go to HKEY_CLASSES_ROOT\.jar (the last key is a point plus the extension) and delete it. It completely blows up the association and makes the file type unknown again.
You may need to restart explorer/log off/reboot to see the change.

An alternative way is to use some program to edit the file associations for you. A good option is FileTypesMan - Alternative to 'File Types' manager of Windows

Unfortunately, the screen for touching associations in a nicer way was removed in Vista, so you have to do workarounds.
