Built with Seam

You can find the full source code for this website in the Seam package in the directory /examples/wiki. It is licensed under the LGPL.

In Seam, a message can be easily sent to a JMS queue by using the QueueSender and QueueSession components (see Seam Reference, chapter 19). However, I was not able to figure out how to configure them to access a security-enabled JMS queue (i. e.: a queue that requires a user and password).

The workaround below will override Seam's built-in QueueConnection so a user and password can be provided. All you need to do is create this class somewhere in your Seam app. No additional configuration is necessary (other than the ones outlined by the Seam Reference, of course)

import javax.jms.JMSException;
import javax.jms.QueueConnectionFactory;
import javax.naming.NamingException;

import org.jboss.seam.ScopeType;
import org.jboss.seam.annotations.Create;
import org.jboss.seam.annotations.Destroy;
import org.jboss.seam.annotations.Install;
import org.jboss.seam.annotations.Name;
import org.jboss.seam.annotations.Scope;
import org.jboss.seam.annotations.Unwrap;
import org.jboss.seam.annotations.intercept.BypassInterceptors;
import org.jboss.seam.jms.ManagedQueueSender;
import org.jboss.seam.util.Naming;

@Install(precedence=Install.FRAMEWORK, genericDependencies=ManagedQueueSender.class)
public class AuthenticatedQueueConnection
        private final String CONNECTION_FACTORY_JNDI_NAME = "UIL2ConnectionFactory";
        private final String USER = "queue_user"; 
        private final String PASSWORD = "queue_password";
        private javax.jms.QueueConnection queueConnection;
        public void init() throws NamingException, JMSException
                QueueConnectionFactory connectionFactory = 
                queueConnection = connectionFactory.createQueueConnection(USER, PASSWORD);
        public void destroy() throws JMSException
        public javax.jms.QueueConnection getQueueConnection()
                return queueConnection;

To receive messages from a secured JMS queue, add the following annotations to your MDB:

@ActivationConfigProperty(propertyName="user", propertyValue="queue_user")
@ActivationConfigProperty(propertyName="password", propertyValue="queue_password")
