But more details are needed.  The new EMF will have to be kept and used separately from any other EMFs and only Application Managed EMs will work.  Container Managed EMs will always use the original EMF created by the user.
If you can get more details that would great.

Gordon,

 

I recommended this approach some time last week, but it didn't seem to work.

I don't know what was the configuration (J2E or JSE).

 

Thanks,

 

Andrei

If you need two ServerSessions to co-exist, try using "eclipselink.session-name" property:

Map prop1 = new HashMap();

// populate prop1

prop1.put("eclipselink.session-name", "session1");

EntityManagerFactory factory1 = persistence.createEntityManagerFactory("MyPU", prop1);

Map prop2 = new HashMap();

// populate prop2

prop2.put("eclipselink.session-name", "session2");

EntityManagerFactory factory2 = persistence.createEntityManagerFactory("MyPU", prop2);

 

I believe that should work but couldn't find a test and haven't tried it myself.

Thanks for your reply. I tried putting this property in the map, but the resulting factory has a ServerSession with the first ServerSession's name. I.e., my first factory was created with eclipselink.session-name = "default", and the second with eclipselink.session-name = "newdb",but the second factory still has a ServerSession with the name "default".

Is there perhaps some other config that needs to be done? This got my hopes up!

Thanks again.
