Re: Cocoa-Java Bridge collapse

This was posted today on TheServerSide -- anyone have any comments? As a Java developer, I'm curious if Apple is trying to ween Mac app developers from Java and steer them toward Cocoa development

    All I can say about this is:  I hope they don't!

    I'm in the situation where I have a very large, existing library of existing classes in Java which have taken several man-years of development (with only one "man" at that).  It encapsulates protocols, hardware communications and abstraction, and a LOT of data manipulation.  Re-writing all of this in Objective-C isn't really realistic.

    However, as this engine was designed to allow any GUI to be easily layered atop it to create an application (via a callback interface such a GUI needs to implement), creating a Cocoa-Java version has been a snap.  I'm now able to give Apple users of my software a tightly integrated version of my app for their (and my!) platform of choice, while still supporting Linux, Windows, and OS/2 users via the standard Swing interface.

    I'm no stranger to Objective-C -- some of my recent projects have been pure Objective-C -- but re-writing all of this heavily tested Java code to Objective-C isn't feasible.  Which either means I'll have to retract my Cocoa support and have Mac users use the same Swing GUI everyone else is using, that I'll simply have to eschew whatever new features are added to Cocoa but aren't reflected in Cocoa-Java, or that I'm going to have to write my own JNI routines to access said features.

    (Of course, I suppose the Open Source community could always create its own libraries to encapsulate the functionality for any Cocoa routines which aren't in Cocoa/Java.  Hey Apple -- if you're not going to maintain this technology, why not Open Source it so the community can keep it up for you?)
