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?
.jar is not an application. It's just a java file. You'd set the JVM to be the handler for .blah files, with the .jar loaded as a permanent arg for the jvm call
