So, eliminating the XIDFactory makes this cleaner, but giving the JmsServerSession still requires the TransactionManager. My plan is to have the JMSActivation look this up via JNDI and provide it to the JmsServerSessionPool. Obviously when I can *finally* get around to going back to real work and not IBM support we can do this differently.
