I've been developing J2ME software for a year or so on my Mac, targeting MIDP 1.0.
I'm using Xcode to write the actual source code. But then I go to the command-line to finish the job. For each project, I'll whip up some shell scripts to compile all the classes, run the preverifier, and launch the X11-based emulator. I also use scripts to build the jar file.
It's all working fairly well for the kinds of things I do. I don't miss the WTK at all. But I can't help but feeling like I'm underutilizing Xcode. I'll admit to being clueless as to how to set up build targets and such in an IDE, but couldn't you, in theory, compile, preverify, and run from right there in Xcode? Anyone out there doing this? Anyone with "nuts and bolt" Xcode knowledge that could offer a few tips?
