Hello

I am developing a java application with Eclipse RCP.

For the persistence of data I used JPA. The problem is that I can not integrate the two into a single project.

When I run my classes as JPA java bean everything works perfectly but when I try to integrate with RCP, it leaves me this error:

Someone can tell me where is the problem? or have an idea to integrate jpa with eclipse rcp application.

Thank you in advance for your help.
