Yep, that's right.  XADataSource does not specify any methods for
setting the connection properties.  Bummer, huh?  I see three
possible solutions.

 - Write a bridge class that delegates to or extends the specific
   XADataSource implementation you want to use and also has setURL
   and setProperties methods that call the appropriate methods in
   the actual implementation.

 - Use the XA JDBC resource adapter that is part of JBossPool.
   This involves using RawXADataSourceLoader to bind your
   XADataSource implementation into JNDI, then setting up a
   ConnectionFactoryLoader that specifies the properties that
   should be set.  There is an example commented out in jboss.jcml.

 - Modify XADataSourceLoader to use an approach similar to
   RawXADataSourceLoader, i.e. allow the method names to be
   specified in jboss.jcml.

Good luck,
Toby.
