The comments in org.jboss.resource.adapter.jms.JmsManagedConnection provides some insight to this case inside an application server: * <p>From the JMS tutorial: *    "When you create a session in an enterprise bean, the container ignores *    the arguments you specify, because it manages all transactional *    properties for enterprise beans." * * <p>And further: *    "You do not specify a message acknowledgment mode when you create a *    message-driven bean that uses container-managed transactions. The *    container handles acknowledgment automatically." So the above case would be out-of-scope. -------------------------------------------------------------- Reply to this message by going to Community [http://community.jboss.org/message/538572#538572] Start a new discussion in JCA at Community [http://community.jboss.org/choose-container!input.jspa?contentType=1&...]
