Is there a way to set a .jar application as the default program to open .blah files on Mac OSX? I know how to set a .app as a default application, but the .app is the only file type not grayed out when you go to choose an application as a default.
What should I do about it?
As discussed in Java Deployment Options for Mac OS X, you can create a Mac OS X Application Bundle that “can associate specific document types with your application. This lets users launch your application by double-clicking a document created by your application.” See also more About Info.plist Keys.
