Ok.  From what I understand about this one, the configuration parameters for 
accessing the database are specified by the client, and are not configured in 
the xmlBlaster.properties file on the server side?

If this is the case, I'm guessing the connections are not pooled?

I had this one figured out.  I was just curious if xmlBlaster supported 
'bindings', so that I could decide at runtime which database binding I wished 
to use for my queue or topic.  Similar to how I would use a database within 
an EJB container for MDBs.

Thank you for your response.  It was quite helpful.
