Should have been "When you saying 'two separate parameters', do you mean allow it to be configured centrally in the jbossesb-properties.xml and then override it in the JNDI config?" I hadn't meant that as I had assumed that the default behaviour would be as now, so if the user does not specify it then it works the same. I was thinking more from the configuration aspect, supporting both an XA and a non-XA version of this parameter within JNDI. If we choose to do this then the user can set it up once in the jms-provider and the same configuration/pool can be shared between all the associated listeners, whether transactional or not. If there is only a single JNDI parameter then the user may get into problems if they mix transactional/non-transactional listeners and would have to be aware of the issues.
