Convert J2EE source code to J2ME code

I'm not sure where you're going at here.

Basically J2EE and J2ME code does not differ. The difference is in the set of libraries used and of course the target platform.

J2EE code basically uses J2EE libraries (EJB, Servlet, ...) and is targeted at the enterprise world. The target machines have loads of CPU and memory.

J2ME code uses J2ME libraries (Midlet, CLDC, ...) and is targeted at small, resource-constrained devices such as cell phones, PDAs and set-top boxes.

Both platforms are created on top of (a subset of) the J2SE and need a JVM implementing these standard APIs to work.

It depends on your requirements.

J2EE contains a set of classes and libraries which are to be used on the server side. Apart from this, the language is the same.

I don't think you need to run server-side software on your J2ME device, but I need more detail to help you.

Let me ask you one thing , what do you want to achieve in the first place .
 Since J2EE , J2ME are designed having two entirely different domains in mind.
