The JMS/JCA adapter is meant to be used exclusively in a managed environment (ie Servlets/EJBs). To get a JMS connection in a standalone client you want to use ConnectionFactory cf = (ConnectionFactory)initialContext.lookup("ConnectionFactory"); Note, the above is for JMS 1.1. For JMS 1.0.1b clients you would cast to the specific domain type (ie Queue/Topic). View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=3961029#...
