RE: MDB not invoked
Hi David, I'm not sure how to see the resources and binding in jmx-console, in fact, I don't know how to start jmx-console in openejb. -- View this message in context: http://openejb.979440.n4.nabble.com/MDB-not-invoked-tp4548110p4553890.html Sent from the OpenEJB User mailing list archive at Nabble.com.

I did take a close look at your logs earlier and can verify this won't do anything (these things were being created already automatically). I think what we need is a log line that says what the server understands is the Topic/Queue name of the MDB. I had thought I added that as I've had this problem before as well. I could be misremembering, though. Anyway, once we get actual confirmation that the bean is truly tied to the queue/topic expected, then it's a simple act of using a JMX Console to see what the JMS broker is doing with the messages. Via JMX you can see how many consumers (if any) there are for each Topic and Queue. There should be at least one for the MDB itself. Regardless of the logging, definitely do grab jconsole and attach to the broker's JVM and see what Topics and Queues there are and how many producers and consumers for each. Let us know what you find and we can see what the next step might be. -David
RE: MDB not invoked
Hi Romain, I did try to config it in openejb.xml like below as well, but it just didn't work for me. -- View this message in context: http://openejb.979440.n4.nabble.com/MDB-not-invoked-tp4548110p4553537.html Sent from the OpenEJB User mailing list archive at Nabble.com.
RE: MDB not invoked
Hi,
I have tried to setup it following the examples, but just not working for me.
Here are some codes:
1) No annotation in mdb , just a onMessage method. The ejb-jar.xml:
StandardReportsBean
se.it.newjena.reports.bean.receivers.StandardReportsBean
javax.jms.MessageListener
destination
ReportStandardJMSQueue
destinationType
javax.jms.Queue
jms/tdm-newjena/ReportStandardJMSConnFactory
javax.jms.ConnectionFactory
ReportStandardJMSQueue
javax.jms.Queue
2) The resources in the server.xml for tomcat in Eclipse:
3) The code to send message:
QueueConnection queueConnection = null;
QueueSession queueSession = null;
Queue queue = null;
QueueSender queueSender = null;
ObjectMessage message = null;
try {
// check if jndiContext and queueConnectionFactory are set if not
// throw an exception
if (jndiContext == null || queueConnectionFactory == null)
throw new Exception("InitialContext or QueueConnectionFactory
is not set");
/*
* Look up queue.
*/
queue = (Queue) jndiContext.lookup("ReportStandardJMSQueue");
queueConnection = queueConnectionFactory.createQueueConnection();
queueSession = queueConnection.createQueueSession(false,
Session.AUTO_ACKNOWLEDGE);
queueSender = queueSession.createSender(queue);
/*
* Send message
*/
message = queueSession.createObjectMessage();
message.setObject(wrapper);
queueSender.send(message);
logger.info("Jena reports - a message has been sent");
}
I also tried the below in ejb-jar.xml, but it will say the queue has
binded to context, and if I removed the resource for this queue in server.xml,
then it can't find the queue for sending messages.
ReportStandardJMSQueue
javax.jms.Queue

Subject: Re: MDB not invoked
Hi,
how did you configure:
1) the mdb
2) the jmx resources (queue, connection factory, ...)
3) the client
?
it sounds like a config error. If you can share some code we could help you
more efficiently.
Note: some JMS sample are here:
