Hard Code

These days I am very busy developing a large and complex web application, which is nearing its first release. This web based product runs on Tomcat 6 and will be deployed on http://www.mydomain.com But if I deploy my web application on Tomcat 6, I need to specify the context root. Well this is no good, why will the users of this website be willing to remember the context root. What if the context root changes. In other words the users would not be interest in typing the following - http://www.mydomain.com/myappcontext to visit this site. Hence it is necessary that I change the default / root web application of Tomcat and point it to my application. I wanted to try and test this on localhost first. As always I Googled and found a number of posts and none seem to work. I also read the documentation it was helpful in understanding the concepts but was not effective as I could not get it working. Finally after few hours of trial and error one of my colleague Joyeeta Majumdar found the ...

In my last post, I had shown how you can post a JMS message to a ActiveMQ queue. In this post I will show the reverse process. I will not try to consume this message using a Spring Message Driven POJO. I assume your familiarity with Spring MDP. If not you can look here - http://static.springframework.org/spring/docs/2.5.x/reference/jms.html The operation that I intend to carry out is depicted in Figure 1. Figure 1 - Consuming JMS message using Spring MDP Step 1 - Create the message listener. Listing 1 - EventMessageConsumer.java Step 2 - Wire up the bean in Spring configuration Listing 2 - spring-activemq-config.xml Step 3  - Test Finally you can see the results of message produced and consumed in the Admin web console as shown in Figure 2. Figure 2 - Queue statistics

Last Updated 04/16/2017 In this post, I will show how you can send JMS message to ActiveMQ from your Spring web application. I have a Spring 2.5 + JBOSS Richfaces based web application that runs on Tomcat 6 running on JDK 5. Figure 1. depicts what I intend to do. Figure - 1 Send JMS Message to ActiveMQ using Spring from a web application Step 1: Drop in the following jars to WEB-INF/lib activemq-core-5.2.0.jar jms.jar geronimo-j2ee-management_1.0_spec-1.0.jar Step 2: Create the destination/Queue using the ActiveMQ admin web application. Launch your browser and point it to - http://localhost:8161/admin/ Figure 2 - ActiveMQ Admin Console Click on 'Queues' to navigate to queue list and create screen. You will need to supply the queue name and click on 'Create' to create a new queue destination on ActiveMQ server. This is shown in Figure 3. Figure 3 - Create a new Queue Step 3. Create a message producer interface . This may not be necessary...
