Integration

I got this exception when I tried to run my JSF/EJB3-JPA-TopLink Essentials application.
The application generated 6 Entities from 6 database tables and 6 XML files describing those 6 entities. I also added native SQL queries into orm.xml file.

I got exception when trying to run application:

Internal Exception: oracle.classloader.util.AnnotatedClassNotFoundException:

Missing class: model.MyClass.class

Does anybody know workaround?

This is full trace:
