BlackBerry Library problems. (jre6 + NET_RIM_BLACKBERRY)

Question

Hi Everyone, I'm new in blackberry environement programming, I'm developing an application for this device and there are some probs about libraries that I don't understand.

I have the main project called:

npoBBerry - his library is NET_RIM_BLACKBERRY (from 4.6.1 version...) it includes other two projects:

1. Npo - his library is standard jre6 (Npo inlcudes NpoCore)
2. NpoCore - his library is standard jre6

Compliance was set... In Java Compiler level is set to 1.4 for all.

Now the problem is that I'm not able to build my project. 4 errors:

1. Error preverifying class ch.yek.npo.model.Advertising
2. Error preverifying class ch.yek.npo.repository.Repository$1
3. Error!: Error: preverifier failed: C:\Program Files\eclipse\plugins\net.rim.eide.componentpack4.6.1_4.6.1.27\components\bin\preverify.ex ...
4. Error!: Error: preverifier failed: C:\Program Files\eclipse\plugins\net.rim.eide.componentpack4.6.1_4.6.1.27\components\bin\preverify.ex ...

I know that libraries are differents but maybe I'm missing something.

NpoCore represents models, interfaces Npo just take data from a repository NpoBBeryy just use this data from Services...

Please help and thanks in advance... :)

BlackBerry applications conform to the J2ME spec, not J2SE. Therefore, any third-party libraries you use must be specifically for J2ME. There are some classes between J2ME and J2SE that are similar, but there is also a lot in J2SE that is not in J2ME.
