Hi, I'm really quite new to J2ME and I have a quetion that maybe is banal...but thanks in advance for your help!!!

I have an application, delivered in a jar file, and I'd like to use it as a library.

I have the source code of some classes and I'd like to use their functionality, by means of extending them. (In the sense of the keyword Java "extends")

I've tried to do this work, by means of Wireless development toolkit...without success

Two questions:
1. Is it possible to do this work?
2. Is there a toolkit that can help me?

thanks a lot
