remove @TransactionManagement(value = TransactionManagementType.BEAN) in most case you don't want to handle tx management yourself View the original post : http://www.jboss.com/index.html?module=bbop=viewtopicp=3956549#3956549 Reply to the post : http://www.jboss.com/index.html?module=bbop=postingmode=replyp=3956549 - Using Tomcat but need to do more?

Hi, your English is just fine! The issue is you are trying to acquire a transaction in a component that manages transactions for you. Remove the | | manager.getTransaction().begin(); | manager.getTransaction().commit(); | | and the associated rollback. For the distributed (multi DB) transaction you just need two XA datasources. Please see http://wiki.jboss.org/wiki/Wiki.jsp?page=JBossJCA to learn how to set up XA datasources.
