Although the JPA spec has provided options for a container to override
things like jta-data-source name while calling
PersistenceProvider.createContainerEMF, GlassFish does not currently
leverage it. File an RFE. Currently your option is to directly call
Persistence.createEntityManagerFactory and pass different values in the
Map parameter. You have to take care of things like transaction
management and life cycle of entity managers explicitly in your EJB with
this approach.
