Java .jar files to run on double-click

Question

How can I configure .jar files run on double-click in Windows 7?

Solution 1

Open regedit.exe search for : HKEY_CLASSES_ROOT\jarfile\shell\open\command

Probably, you have in the value:"C:\Program Files\Java\jre7\bin\javaw.exe" -jar "%1" %* change it to "C:\Program Files\Java\jre7\bin\java.exe" -jar "%1" %*

(make sure that the path points to your actual java.exe, for it depends on the java version you have installed)

Good luck. It worked for me. ;-)

Instructions for configuring the file assocations you'll need can be found here:

Actually it's not necessary to use javaw. java.exe is ok for me. But the whole command was missing.

Buy a tool for this? You must be kidding.
