Re: Java Cocoa Bindings: not yet implemented?!

Hi Scott


finally somebody who answers, thank you!
seems that nobody does Java Cocoa...

Yes, that's usually what we can read if asking something about Cocoa
Java: "Do it in ObjC." And yes, you're right, ObjC is not as
complicated and a very beautiful language.
And yes, you're right: the documentation for Cocoa Java is bad,
Java-integration in XCode is "forthcoming", and it is often more easy
to do Cocoa in ObjC.

But the point is:
- my business logic is Java and I don't want to rewrite it in ObjC. So
are all my other skills like XML processing, WebService consumption,
Database Access, Threading etc. etc. and it would take _very_ long to
translate this all to ObjC.
- Apple does provide Cocoa Java: so why not use it?
- Cocoa Java does work well expect some limitations in functionality
and documentation, and, as said, in Cocoa binding.
- The ObjC-Java-Bridge (is it that what you mean? or how can I access
Java Object in ObjC) is "legacy". Why? Does it mean it will not work in
future?
