Hi amir,
You should try the trial version of
IBM's WebSphere Everyplace Micro Environment. ASAIK this is the most popular one among J2ME developers who develop for Pocket PCs. Beware that this is not a free software and after you have done developing applications, you might need to buy the full version of the software to deploy the applications on the real devices.
BTW, this forum is not for general J2ME topics. You will find general J2ME geeks out there in
Java 2 Micro Edition forum.
Hope my suggestion helps...
