Question

I am working through the example from https://blogs.oracle.com/arungupta/entry/java_ee_6_and_nosql.

Here is a link to the model src http://dev.eclipse.org/svnroot/rt/org.eclipse.persistence/trunk/examples/org.eclipse.persistence.example.jpa.nosql.mongo/src/

The part that is causing me problems is:

EntityManagerFactory factory;
...
test.factory = Persistence.createEntityManagerFactory("mongo");
EntityManager em = test.factory.createEntityManager();        

When org.eclipse.persistence.internal.jpa.EntityManagerFactoryImpl.createEntityManager is invoked I get

SEVERE: javax.persistence.PersistenceException: Exception [EclipseLink-7108] (Eclipse Persistence Services - 2.0.1.v20100213-r6600): org.eclipse.persistence.exceptions.ValidationException
Exception Description: This operation is not supported for non-relational platforms.

Here are all the dependencies I am using:

Server is GlassFish Server Open Source Edition 3. I can’t figure out why createEntityManager would not be allowed, when I copied it all from example code that worked for others??

Answer 1

The exception shows the EclipseLink build as 2.0.1.v20100213-r6600 while this feature requires EclipseLink 2.4 or later. How ever you setup your dependencies, it seems to be using the EclipseLink version shipped with Glassfish. You can try replacing/upgrading these bundles as described here:
