I was trying to make a small sample to send to you since I can't send most of my source code but while trying to recreate the issue with a sample application i was unable to. It sounds strange but now the program doesn't complain about the missing class, but I do get warnings about jar files. I think that its the reason why it now works, but I would still like to find out how to solve the class loading error, as I may eventually re-encounter it. So I will try and get you a project that produces that error. Here are the warnings I get:
