This can only handle a single jar file, plus an icon file. If the app you want to bundle has any other supporting files, it's useless. A jar bundler replacement. this is not.

The program worked as advertised. I think the negative reviews come from folks who expected too much from this free app.I'm more than satisfied.

Couldn’t get it to create a .app that worked. The jar files were fine but the resulting app launched with error suggesting that the corrupted app be moved to trash. The website link here is a dead end.
