Rococoa allows you to call Objective-C code through Java classes and interfaces that you define.

Welcome to Rococoa

Rococoa is a generic Java binding to the Mac Objective-C object system. It allows the creation and use of Objective-C objects in Java, and the implementation of Objective-C interfaces in Java.

Fair Warning

Rococoa is very much work in progress. Much is subject to change. A lot isn't good enough not to change. But given the recent deprecation of the Java-Cocoa bridge, it's the best I've got. Just mind your head. And please give feedback in the mailing list.

Oh, one big warning. Rococoa on PPC passes all but one of its tests, but that shows that it has an issue returning longs from Objective-C methods. Please do try it on PPC, and report any other problems to the project mailing list.
