Blackberry error starting application: verification error

Question

I'm trying to use libraries in a project. The one i'm using is blackberry's Advanced UI sample library, which i added by creating a jar of it and preverifying it. The code works fine, no issues.

However, I need to include facebook and twitter integration. I'm trying to use facebook sdk 0.8.25 (requires log4b.jar) and twitter ME API 1.8.

I include them in the build path and tick for them to be copied at build. When i run the application i get

Error starting --- Module --- has verification error 2644 at offset 08e5

I've tried each jar separately, log4b give the same issue stating error 190.

any idea what i'm doing wrong?

Managed to fix my own fault with the help of this link http://lwuit.blogspot.com/2009/01/rim-blackberry-verification-errors.html

Basically the device is os6, and the build library was 7.1 which wasn't as issue before. But it seems the imported libs were trying to use the 7.1 api.
