I must be missing something, because I am sure this has been answered, but I can't 
seem to find the answer.

My scenario: I have the typical situation where inside an EJB call, I do some work and 
update my DB via a local resource (MSSQL), and then place a messasge on a JMS queue. I 
am using java:/JmsXA as my lookup for the QueueConnectionFactory.

Given this scenario, and the fact that 4.0 has the Last Resource Gambit, I would 
assume that this would work great. But, I keep getting the 'Prepare called on a local 
tx' warning. 

After tracking it down, I realized that it is not my MSSQL DS that is causing the 
issue (the gamit algorithm skips it fine), but it is in fact DefaultDS that is the 
issue -- which makes sense. JBossMQ has to save it's information somewhere, and is 
using HSQL as the default. And that connection is a local resource as well.

After reading the FAQ's, I realize that I need to change the db that JBossMQ is using 
to persist it's information. I am happy to change it to use my MSSQL Datasource. 

But, am I not going to run into the same issue? In this scenario, I am always going to 
have 3 resources: my JDBC work, MQ's JDBC work, and the MQ Spy resource.

Is there a proper way to configure it so that I can allow my MSSQL DS to be the only 
local resource, and thus allow the LRG algorithm to work? If I tell MQ to use my MSSQL 
DS, will it then only count as one resource, and be the allowed local resource in an 
XA TX?
