The problem seems to pertain to this bug listed in another thread which I am wondering what the status is:

“the JPA metadata validator hasn’t been expanded to do the class resolution across project boundries like that. This has not been changed in 7.0 but it’s been filed as a bug for us to look into.”

We use MyEclipse for reverse engineering JPA entity beans. Each entity bean has a super class that contains the id and version field. The super class is in a different (utility) project.

At runtime everthing works fine, but MyEclipse ide shows the following error message:

bchrist2,
Can you clarify if the Driver and Catalog Schema are set correctly from Project > Properties > MyEclipse > Java Persistence?
Also, can you list out the steps in detail, right from the project creation, to replicate your issue?
