javax.persistence.PersistenceException: No Persistence provider for EntityManager named ... in JBoss EAP 6

Issue

• We have a security login module where we are trying to use JPA / Hibernate EntityManager to read from a database. We have our login module inside of a custom module which depends on jpa and hibernate modules as shown below. But we are getting the error 'javax.persistence.PersistenceException: No Persistence provider for EntityManager named' when trying to get the EntityManagerFactory via:

EntityManagerFactory emf = Persistence.createEntityManagerFactory("SecurityPersistenceUnit");
