About Creating JMS Web Services from MDBs

To create a JMS web service from an MDB, you must have a project containing a message-driven bean, and the onMessage() method of the implementation class should contain some Java code that runs whenever the bean receives a message.

In configuring the MDB, you have to edit the orion-ejb-jar.xml file, select the MDB from the list of beans displayed and supply the JNDI locations of the JMS destination, and a JMS connection factory. These are JMS artifacts that live in the JNDI namespace, and they are added to the JNDI namespace by modifying one or more of the OC4J configuration files.

To edit the orion-ejb-jar.xml file:

If orion-ejb-jar.xml is not listed in the navigator, add it to the project.
Right-click orion-ejb-jar.xml, and choose Open. The XML file opens in JDeveloper's code window, and you can make the changes you need.

Once the MDB has been deployed to the application server, you can use JDeveloper's JMS Web Service wizard to define a web service that can be used to access the MDB. See Creating a JMS Web Service.
