Hi,
I tried to follow the WIKI "UsingWebSphere MQ Series with JBoss Application Server - Part I" with the following environment:
Win 2000 Prof.
SUN JDK 1.5.0_07
JBoss 4.0.4
WebSphereMQ 6
ant 1.6.5
All the stuff running in a VMWare virtual machine.

I have customized all the settings as described. Running the ant mb-deploy command to deploy the custom MBeans into JBoss I receive the following error:
2006-08-14 04:46:33,514 DEBUG [org.jboss.system.ServiceCreator] About to create bean: jmx.service.wsmq:service=WSMQRequestQueue with code: jmx.service.wsmq.WSMQDestination

Does anybody have the same problem?
The creation of some other MBeans works fine i.e. :
2006-08-14 04:46:33,436 DEBUG [org.jboss.system.ServiceCreator] About to create bean: jmx.service.wsmq:service=WSMQXAQueueConnectionFactory with code: jmx.service.wsmq.WSMQConnectionFactory
2006-08-14 04:46:33,514 DEBUG [org.jboss.system.ServiceCreator] Created bean: jmx.service.wsmq:service=WSMQXAQueueConnectionFactory

Thanks in advance
Marcel
