You can use the command "service:list NamespaceHandler". It will list all namespace handlers in the attributes you can see the namespace they support.
Does openjpa 2.2.2 work well with Aries JPA 2.x for you? The problem is that openjpa is not jta 1.2 compatible. So it can not be used with the new Aries transaction 2.0.0. As the old Aries transaction 1.3.0 is also installed this might work but I never tested this combination. I hope openjpa 2.4.1 will be out soon which works well with the newest version of Aries JPA and Aries transaction as it supports jta 1.2.
