Best way to pause delivery of messages on a queue

[rnicholson10]

I have a situation whereby it would be helpful to be able to stop delivery of messages on a queue but still allows client to add messages to the queue in question.

I see that there is a stopDelivery method in the JMSContainerInvokerMBean.

Will calling this stop delivery and still allow clients to add messages to the queue?

Is is this the same as the stop command in the JMX console? If it is then it would stop messages being added to the queue. In this case is there another way to do this?

Thanks,

Ross

Can you name the version of JBoss Messaging?

[rnicholson10]

1.4.3.GA, comes with the 5.1.0 Beta of AS 5.

Not sure about JMSContainerInvokerMBean as I can't find it in JBM code base. Did you try use Connection.stop()?

[rnicholson10]

I'm using MDB's so I won't have direct access to the connection.

I simply want the MDB to stop firing onMessage until I tell the queue to start delivering again (without stopping clients from sending messages to the queue).

I have the following code for JMSContainerInvokerMBean (it's in the package (org.jboss.ejb.plugins.jms):

MBeanServer mbeanServer = MBeanServerLocator.locateJBoss();
JMSContainerInvokerMBean invoker;
try
{
 invoker = (JMSContainerInvokerMBean) MBeanProxy.get(
 JMSContainerInvokerMBean.class, objectName, mbeanServer);
 if (method == STOP)
 {
 invoker.stopDelivery();
 }
 else if (method == START)
 {
 invoker.startDelivery();
 }
}
catch( Exception e)
{
 e.printStackTrace();
}

Would the JMX forum be a better place to ask this question? Unfortunately the documentation is not very informative concerning the method calls above.

I think the AS forum is also a good place to go as it concerns MDB.
