Here is what I have finally found. Just as background, I am porting a fairly substantial business application from the J2ME MIDP environment to a PDA environment. The LCDUI in the J2ME MIDP/CLDC stack just looks far too clumbsy on the larger PDA screens.
Espresso from http://www.espial.com
is very nice, but very expensive. Not only do they want over $10K for the dev licence, they also want a hefty RTU licence for each product you sell. They are more in the market of selling full java environments for large platform companies to embed in their products. For example, Samsung might want to sell a PDA based on a Java OS and need a PIM. Hence, their prices are not aimed at the ISV.
On the other hand, I found this very nice package from a cool group of 4 guys from Belarus
Look at the LwVCL from http://www.zaval.org
The documentation is somewhat sparse, but nothing that a good Java Developer can't work with. Although they don't mention it explicitly, it works beautifully in the pjava (PersonalJava) environment (my target environment) and it actually is aimed not at being built ontop of AWT, but replacing it with a more efficient GUI library. It looks very promising so far.
I also know about SuperWaba, but alas, since SuperWaba has a very small intersection with java (only java.lang), I would need to rewrite all my non-API code too.
Thanks for all the responses, and I hope that this information is useful for others.
