You are using the XA datasource improperly. XA means that you want JBoss to manage transactions for you. Do you want to manage the transactions yourself? If so, you would want to look at using a no-tx-datasource and do the rest yourself. For what you have described, and looking at your stacktrace, this is probably the better bet for you at this point.
