Turning a Java jar into an Application bundle (OS X)

·

LaunchBar doesn't run jar files, so they need to be turned into applications:

  1. Open /Developer/Applications/Java Tools/Jar Bundler
  2. Under 'Build Information', choose the .jar file as the Main Class.
  3. Select the Java version to use (1.4* uses any 1.4.x version; 1.4+ uses any version that is 1.4 or higher, including 1.5).
  4. Under 'Properties', tick 'Set Working Directory to Inside Application Package'.
  5. Press 'Create Application...' and save the double-clickable application bundle to your Applications folder.

This doesn't work for every .jar file, but it does work for WordBiz at least.
