You can also set up Eclipse to handle J2ME development.
It is really simple: remove the reference to the JRE in the Libraries tab of the
Java BuildPath for your J2ME project and replace it with the midpapi.zip (from the WTK104/lib directory) or the midpapi10.jar/midpapi20.jar (from the WTK21/lib directory).
Then call up antenna tasks via
ant and you are off!
