Hi, I am getting an exception when my MDB gets deployed. It is trying to use DefaultJMSProvider. Can we change the default JMS provider to Websphere MQ JMS provider? Here is the log: Failure in jms activation org.jboss.resource.adapter.jms.inflow.JmsActivationSpec@422a422a(ra=org.jboss.resource.adapter.jms.JmsResourceAdapter(a)3fd43fd4 destination=queue/toILR isTopic=false tx=true durable=false reconnect=10 provider=java:/DefaultJMSProvider user=null maxMessages=1 minSession=1 maxSession=15 keepAlive=60000 useDLQ=true DLQHandler=org.jboss.resource.adapter.jms.inflow.dlq.GenericDLQHandler DLQJndiName=queue/DLQ DLQUser=null DLQMaxResent=5) java.lang.ClassCastException: com.ibm.mq.jms.MQQueue incompatible with org.jboss.mq.SpyDestination at org.jboss.mq.SpyConnectionConsumer.(SpyConnectionConsumer.java:110) at org.jboss.mq.SpyConnection.createConnectionConsumer(SpyConnection.java:128) at org.jboss.resource.adapter.jms.inflow.JmsServerSessionPool.setupConsumer(JmsServerSessionPool.java:289) at org.jboss.resource.adapter.jms.inflow.JmsServerSessionPool.start(JmsServerSessionPool.java:89) at org.jboss.resource.adapter.jms.inflow.JmsActivation.setupSessionPool(JmsActivation.java:585) at org.jboss.resource.adapter.jms.inflow.JmsActivation.setup(JmsActivation.java:323) at org.jboss.resource.adapter.jms.inflow.JmsActivation$SetupActivation.run(JmsActivation.java:635) at org.jboss.resource.work.WorkWrapper.execute(WorkWrapper.java:204) at org.jboss.util.threadpool.BasicTaskWrapper.run(BasicTaskWrapper.java:275) at EDU.oswego.cs.dl.util.concurrent.PooledExecutor$Worker.run(PooledExecutor.java:756) Thanks Siva View the original post : http://www.jboss.org/index.html?module=bb&op=viewtopic&p=4222583#...
