Hello, Thanks for your immediate reply. Actually, I need to test JMS on Clustering mode of JBoss AS. So, I have to use JMS for saving the some info on queue and send that queue info as a mail to the user. Is it possible using Message Driven Beans?? or, I think, I have to edit mail-service.xml file in <JBOSS_HOME>/server/all/deploy path. Any suggestion??
