The J2ME Wireless Toolkit 2.0 seems to have taken a lot of headaches out of J2ME development. I messed around with the Wireless Toolkit 1.x a few months ago, but didn’t get much further than the basic demo.
I really like that I don’t have to drop to the command line in order to build or deploy. I don’t have to write a jad in a text editor, it’s generated for me. All of the basic properties are easily accessable.
Of course, if I were working on a project in a production situation, I would probably use Antenna, a collection of ant tasks for Ant 1.5.x that allows you to build, preverify, create JADs, and do all the other stuff that all the cool kids are doing. It’s released under the LGPL.
I’ll definately have to look into this.
