Problem creating queues dynamically

[barrys52]

Please help!

I am using JBoss Messaging 1.0.1.CR2 and need to create/deploy queues dynamically. (That is, the queue should not be defined in the destinations-service.xml config file).

The QueueExample that came with JBoss Messaging seems to demonstrate how to do this (in the deployQueue method of Util.java). The QueueExample runs perfectly when the queue is defined in advance. Trying to create a queue dynamically first requires getting a handle to the MBeanServerConnection object, using the lookupMBeanServerProxy() method:

InitialContext ic = new InitialContext();
 MBeanServerConnection p =
 (MBeanServerConnection)ic.lookup("jmx/invoker/RMIAdaptor");

However, this lookup call results in the following exception:

javax.naming.CommunicationException [Root exception is
java.lang.ClassNotFoundException: org.jboss.jmx.adaptor.rmi.RMIAdaptor
(no security manager: RMI class loader disabled)]
at
org.jnp.interfaces.NamingContext.lookup(NamingContext.java:729)
at
org.jnp.interfaces.NamingContext.lookup(NamingContext.java:588)
at javax.naming.InitialContext.lookup(InitialContext.java:351)
...

============================================
I would appreciate it if someone could explain how to correct this or provide an alternative way to dynamically create/deploy/undeploy queues.

Thanks,
Barry

The issue you are having is a problem with looking up the MBeanServer not a problem with JBoss Messaging per se.

It's probably that you're simply not including the correct jars on the classpath. To find out which jars to include please post on the JMX users forum.

Thanks.

Problem resolved! It turns out that the problem had nothing to do with lack of a security manager. The problem was that I did not have all the jar files required in my classpath. The jar files are contained in the [jboss_home]/server/messaging/lib directory.

Thanks for your help, Tim!
