Hello,

We are using activeMQ 5.2


We followed activeMQ instructions on how to add a queue to JBoss server, we are using it with following code, which worked great when we were using activemq + tomcat 5.5:

   try {
                initCtx = new InitialContext();
                QueueConnectionFactory connectionFactory =
   (QueueConnectionFactory)initCtx.lookup(this.connectionFactoryJNDIName);
                Queue destination =
   (Queue)initCtx.lookup(this.queueJNDIName);
                QueueConnection queueConnection = null;
                try{
                    queueConnection =
   connectionFactory.createQueueConnection(); // throws error
                    // snip
                } finally {
                    try{
                        if (queueConnection!=null)
                        queueConnection.close();
                    } catch (JMSException e){
                        log.error("Could not close event
   queue"+queueJNDIName,e);
                    }
                }


However, on a regular basis, we get this error message from this code, which happens for unknown reasons:

   javax.jms.IllegalStateException: Setting clientID on a used
   Connection is not allowed

This is a major problem for us, as if message are not delivered to queue, the processes that must send those messages refuse their operations, leading to user operation being canceled, leading to angry users. Why is activeMQ sending those error message, how to prevent them? Did i do sometinh wrong. Also, here is our queue definition in jboss:

   <tx-connection-factory>
   <jndi-name>activemq/QueueConnectionFactory</jndi-name>
   <local-transaction/>
   <use-java-context>false</use-java-context>
   <track-connection-by-tx/>
   <rar-name>activemq-5.2.0.rar</rar-name>
   
<connection-definition>javax.jms.QueueConnectionFactory</connection-definition>
   <ServerUrl>tcp://localhost:61616</ServerUrl>
   <UserName>*******</UserName>
   <Password>*******</Password>
   <min-pool-size>1</min-pool-size>
   <max-pool-size>200</max-pool-size>
   <blocking-timeout-millis>30000</blocking-timeout-millis>
   <idle-timeout-minutes>3</idle-timeout-minutes>
   </tx-connection-factory>

   <mbean code="org.jboss.resource.deployment.AdminObject"
   name="activemq.queue:name=myqueue">
   <attribute name="JNDIName">activemq/queue/myqueueentry</attribute>
   <depends
   
optional-attribute-name="RARName">jboss.jca:service=RARDeployment,name='activemq-5.2.0.rar'</depends>
   <attribute name="Type">javax.jms.Queue</attribute>
   <attribute name="Properties">PhysicalName=WF.IncomingEvents</attribute>
   </mbean>




At about the same time, on a regular basis, randomly, one of our activeMQ clients get stuck in a receive() call. The analysis of activemq server show that this client is not longer connected (number of consumers on queue=0), and a netstat on the client machine show that there is no more TCP connection between client and server. However, for some unknown reason, the receive() call does not fail, it just get frozen inside activemq api, on a wait() call, which does not look very reliable.


thanks for any kind of help, we are a bit clueless on this for now.
