I have been more or less following the popular UsingWebSphereMQSeriesWithJBossAS tutorial to configure JBoss to communicate with Websphere MQ. Things seem to be working as described, however, when I try to deploy a MDB with a <message-driven> destination of the Websphere MQ I receive the following error: 10:45:03,182 WARN [JMSContainerInvoker] JMS provider failure detected for ListenBean javax.jms.JMSSecurityException: MQJMS2013: invalid security authentication supplied for MQQueueManager at com.ibm.mq.jms.MQConnection.createQM(MQConnection.java:2050) at com.ibm.mq.jms.MQConnection.createQMNonXA(MQConnection.java:1532) at com.ibm.mq.jms.MQQueueConnection.(MQQueueConnection.java:150) at com.ibm.mq.jms.MQQueueConnectionFactory.createQueueConnection(MQQueueConnectionFactory.java:185) at com.ibm.mq.jms.MQQueueConnectionFactory.createQueueConnection(MQQueueConnectionFactory.java:112) etc. The Websphere MQ server is not local to my machine. It seems like I would have to supply a username / password to the MDB as soon as it establishes the "listening" connection on that queue, but I cannot figure out where in the deployment files to do this. Any help would be appreciated, I have been stuck on this for days, let me know if I need to post more info/ complete stack trace.
