Developing for iPhone with Java and XMLVM
From the Mac Java Community: Coke and Code blogger Kevin Glass describes a roundabout means of using Java to create iPhone applications in Portable Game Code - Applet / Android / IPhone - Part 1. "I like Java, I find it very productive. I don't particularly want to alot of work in Obj-C. One code base is better for me, one set of bugs to fix. Being able to test the same code an applet, before having to go to my Mac and IPhone is better. Enter XMLVM, it's a tool that converts from Java byte code into an XML document, and then translates this into other languages - one of these being Obj-C. Ok, it's not really as simple as that but I'll describe the details in the next post."
