Thanks for someone pointing to me this article http://activemq.apache.org/jmstemplate-gotchas.html

I am able to resolve the issues and getting a significant gain in performance by doing this:

bean id="connectionFactory" class="org.apache.activemq.ActiveMQConnectionFactory">

Great and simple article to follow. I tried it on Spring 2.5.5 and Apache Active MQ 5.1 and it works from the example above. Note that the class name has changed to org.apache.activemq.command.ActiveMQQueue and org.apache.activemq.ActiveMQConnectionFactory.

I modifIED the RegistrationConsole.java to test sending 1 million messages in a loop, but I got the following exception after hundreds of messages.

I modified your application so that it has a client and a server webapp. It works great.
Then I modified it so that it works with JNDI, the server application does not seem to issue a reply whereas when I check the activemq mysql database, I see those messages sent from the client side. It does not seem to work… Thanks for suggestions.
Here are my config files:
web.xml:

ActiveMQ JMS Connection Factory
jms/ConnectionFactory
org.apache.activemq.ActiveMQConnectionFactory
Container

ActiveMQ request Queue
jms/requestQueue
org.apache.activemq.command.ActiveMQQueue

ActiveMQ reply Queue
jms/replyQueue
org.apache.activemq.command.ActiveMQQueue

context.xml:

shared-context-jndi.xml:

org.apache.activemq.jndi.ActiveMQInitialContextFactory

requestQueue
replyQueue

java:comp/env/jms/ConnectionFactory

requestQueue

replyQueue
