Event node not consuming messages

Question

Hi
I am sending an XML message from a different application to WLI destination WLI_BPM_Event
queue using JMS and have an event node in a workflow in BPM waiting for the message.
I see the message reaching the destination ( in console ) but it is in pending
state and is not being consumed by the event node. On the other hand if I use
a dummy workflow template to post the same xml message to WLI_BPM_EVENT queue
in WLI, the message is being consumed by the event node in the original workflow.
Do you have any idea as to what could be the reason for this?
Here is the sample code in onMessage of my MDB that is sending the message to
BPM. It is a simple starting point and I am not worried of multiple instances
of workflow too. This code is triggered by the bean after it receives an XML message
from BPM and processes it.
          QueueConnectionFactory workFlowQConnectionFactory =
     ServiceLocator.getInstance().getQueueConnectionFactory("com.bea.wlpi.QueueConnectionFactory");
Queue workFlowQ = ServiceLocator.getInstance().getQueue("com.bea.wli.bpm.EventQueue");
QueueConnection workFlowQConnection = workFlowQConnectionFactory.createQueueConnection();
QueueSession acctRespSession = workFlowQConnection.createQueueSession(
false, Session.AUTO_ACKNOWLEDGE );
QueueSender acctRespSender = acctRespSession.createSender( workFlowQ
TextMessage acctCreationResponse = acctRespSession.createTextMessage();
StringBuffer response = new StringBuffer();
response.append("<?xml version=\"1.0\" encoding=\"ISO-8859-1\"?>");
if ( accountCreated ) {
response.append("<accountCreated>yes</accountCreated>");
} else {
response.append( "<accountCreated>no</accountCreated>" );
acctCreationResponse.setText( response.toString() );
logger.info("Sent message " + acctCreationResponse.getText() );
acctRespSender.send( acctCreationResponse );
Thanks

Hi Chris
How come I don't see a destination by that jndi name in the list of destinations
under the WLIJMSServer in admin console? I double checked in two separate installations.
I didn't do any custom configurations either and that was a default EAI domain
configuration. I see com.bea.wli.bpm.EventQueue and not com.bea.wli.bpm.Event
Thanks

Hi Sreeram,
Try using com.bea.wli.bpm.Event (not com.bea.wli.bpm.EventQueue).
Cheers,
Chris
