Hello All,

JBoss 3.2.2 (latest in the tree)
Oracle 8.1.7

We are getting the following Oracle XA exception calling a Stateless Session
Bean. This session bean uses two datasources - 
oracle-ds.xml (Non-XA)
oracle-xa-ds.xml (XA)

The operations done in the Non-XA datasource should not impact the on-going
transaction.

The same application (ear) gave a different exception on JBoss 3.2.2.RC2.

Hope somebody can throw some light on this.

Thanks in advance for your time/suggestion/comments.
