OpenJPA says: You have supplied colums for FooBar but this mapping cannot have columns in this context

Question

I have some Java entity classes that are working well in my production code. I am writing an automated test for this application where I am reusing the very same classes. When the test application is creating its entity manager this way: ``` Properties props = new Properties(); props.setProperty("provider", "org.apache.openjpa.persistence.PersistenceProviderImpl"); props.setProperty(...); EntityManagerFactory entityManagerFactory = Persistence.createEntityManagerFactory("foobar-upgrade-restful-test", props); EntityManager entityManager = entityManagerFactory.createEntityManager(); ``` The applications throws an error message telling that: ``` Caused by: <openjpa-2.2.0-r422266:1244990 fatal user error> org.apache.openjpa.persistence.ArgumentException: You have supplied columns for "com.foo.bar.server.commontypes.job.CompositeJob", but this mapping cannot have columns in this context. at org.apache.openjpa.jdbc.meta.MappingInfo.assertNoSchemaComponents(MappingInfo.java:382) at org.apach…

Accepted Answer

The error indicates that there is a problem with the mapping information that you provided for `com.foo.bar.server.commontypes.job.CompositeJob`.

I'm guessing the reason it works for JTA, but not resource local most likely has to do with some oddity in the way that metadata is loaded / processed in the different environments. It would be helpful if you post the relevant mapping data from your Entity.
