Glassfish v3: Can't Deploy MessageDriven Bean - Missing Destination JNDI Name

sdoca picture sdoca · Aug 18, 2011 · Viewed 12.9k times · Source

I am trying to deploy an ear that contains an EJB jar. The jar only contains one MDB class:

package my.package;

import javax.ejb.ActivationConfigProperty;
import javax.ejb.MessageDriven;
import javax.jms.JMSException;
import javax.jms.Message;
import javax.jms.MessageListener;
import javax.jms.ObjectMessage;

import org.slf4j.Logger;
import org.slf4j.LoggerFactory;

@MessageDriven(mappedName = "jms/FileUploadedQueue", activationConfig = {
        @ActivationConfigProperty(propertyName = "acknowledgeMode", propertyValue = "Auto-acknowledge"),
        @ActivationConfigProperty(propertyName = "destinationType", propertyValue = "javax.jms.Queue") })
public class FileListener implements MessageListener
{
    private static Logger log = LoggerFactory.getLogger(FileListener.class);

    public FileListener()
    {
        // empty constructor
    }

    public void onMessage(Message message)
    {
        try
        {
            log.info("Received message: " + ((TextMessage)message).getText());
        }
        catch (JMSException ex)
        {
            String error = "Received error code '"
                    + ex.getErrorCode()
                    + "' retrieving message from queue jms/FileUploadedQueue.";

            Exception linkedEx = ex.getLinkedException();

            if (linkedEx != null)
            {
                log.error(error += "Linked exception: ", linkedEx);
            }
            else
            {
                log.error(error, linkedEx);
            }
        }
    }
}

Using Glassfish 3.1.1 (build 12) admin console, I have setup the following:

Resources -> JMS Resources -> Connection Factories:

Pool Name = jms/ConnectionFactory
JNDI Name = jms/ConnectionFactory
Resource Type = javax.jms.ConnectionFactory

Resources -> JMS Resources -> JMS Destination Resources:

JNDI Name = jms/FileUploadedQueue
Resource Type = javax.jms.Queue

Configurations -> server-config -> Java Message Service:

Type = EMBEDDED

When I try to deploy the ear containing the EJB jar, I get this error:

WARNING: PWC4011: Unable to set request character encoding to UTF-8 from context , because request parameters have already been read, or ServletRequest.getReader() has already been called
INFO: GUI deployment: uploadToTempfile

Have I missed some Glassfish configuration?

I replaced the slf4j logging with simple System.out statement to eliminate that as an issue. I got a different error with this root cause:

Caused by: java.lang.IllegalArgumentException: MQJMSRA_AS4001: setDestination:Invalid destination name=jms/FileUploadedQueue

This issue was because I set the "Physical Destination Name" to "jms/FileUploadedQueue" (same as JNDI name). However, the destination name has greater restrictions on valid characters. Changing it to simply "FileUploadedQueue" allowed it to be deployed. From http://markmail.org/message/zetfwrp2hlesynje:

Yes - the failure is due to the "queue/myDestination" being 'Illegal' syntax for the particular JMS provider's physical destination naming syntax - which is provider dependent and not standardized. In this case, GF includes Sun Java System Message Queue and the rules for legal destination names are set by JMQ. Unfortunately, this is not easy to find in the docs - but if you look hard enough, you'll find the following in the MQ Admin Guide on physical destination names.

The physical destination name. The naming rules are as follows:

The name must contain only alphanumeric characters. It cannot contain spaces. * The name can begin with an alphabetic character, the underscore character (_ ) or the dollar sign ($)."
