Hi, I am triyng to deploy the most simple MDB. This just only displays a text through standard output.

onMessage(Message message){
System.out.println("Got a message!");
}

The MDB deploys well, but when I send a message to the
linked queue I get the following message:

14:44:44,627 ERROR [STDERR] java.lang.NoSuchMethodError
at org.jboss.jms.asf.StdServerSession.onMessage(StdServerSession.java:293)
at org.jboss.mq.SpyMessageConsumer.sessionConsumerProcessMessage(SpyMessageConsumer.java:603)

I have tried this on Windows2000 and Solaris and with both BMP and CMP.
Some idea?
Thanks in advance.
