I'm not certain this is the right answer, but with a bit of hacking I was
able to get the behavior you are looking for....
// Get a reference to the mapping repository
MappingRepository repo = (MappingRepository) ((EntityManagerImpl)
em).getConfiguration().getMetaDataRepositoryInstance();
// Get a reference to the class mapping for the Entity we're interested in.
Note, you might need to pass the context classloader if running in a JEE
container.
ClassMapping customerMapping = repo.getMapping(Customer.class, null, true);
// Change the mapping info to use the 'new' table name
customerMapping.getTable().getIdentifier().setName("bas_person_2");
Be advised that the ClassMapping object is shared across the entire JPA
runtime... If you have multiple EntityManager's, changing the table
identifier name will impact every EM.
Hope this helps.
Thanks,
Rick
