Not sure about this. In my experience, it's not very symmetrical. The MessageDrivenContext has a getCallerPrincipal() method. I don't think there's a way to get the password. You can set the username/password for connections using the outbound connection pool: http://wiki.staging.jboss.com/wiki/Wiki.jsp?page=ConfigJMSRA Put this in your tibco-jms-ds.xml (or whatever you use) This way your MDB doesn't have to know about passwords. I'm not sure this is what you want though. View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=3978872#...
