7.11. JMS Checklist

Before moving on to Message-Driven Beans, let's recap what we've done so far:

• Upgraded the web site:

  • Added a "Run Credit Check" link and form.

  • Added a "Run Credit Check" action to the Controller Servlet.

• Added JMS:

  • Created a CreditCheckReqDTO object that holds the user's credit information to send as a JMS message.

  • Wrote the JmsProducer utility class to encapsulate sending a JMS message.

  • Added JMS-based JNDI reference settings to the Web-based deployment descriptors (web.xml and jboss-web.xml).

  • Automated JMS-based JNDI reference settings with XDoclet.

  • Deployed the JMS CreditCheckQueue on JBoss with an MBean.

We developed the code to send a JMS message, and completely deployed your JMS Queue on JBoss. We now need to add a Message-Driven Bean that consumes and processes the credit check JMS message.
