I was able to create queues using deployQueue from the JMX Web console....but when I code it..... I get InstanceNotFoundException (bean not registered) when I use the following code mbeanServer = MBeanServerFactory.createMBeanServer(); ObjectName objName = new ObjectName("jboss.messaging:service=ServerPeer"); mbeanServer.invoke(objName, "deployQueue", new Object[] { "anyname", null }, new String[] { "java.lang.String", "java.lang.String"} ); I am running the above code from a EJB Session bean in the same jboss server. I have done all the steps to replace a Jboss MQ instance to a JBM 1.4 in jboss 4.2.0. I have started the messaging server as I am able to perform this operation from jmx-web console... Can somebody help? -Poonam View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4190849#...
