About JMS Web Services

JDeveloper lets you create web services that let you put messages on and take messages off JMS destinations. One specific application of this is to create JMS web services from message-driven beans (MDB), a type of Enterprise JavaBean that listens for messages on a JMS destination and acts according to the content of the message.

Each JMS web service is configured to transfer messages to and from a specific JMS destination or pair of destinations. A JMS web service can have the following operations:

Send, where the client supplies an XML element as the operation's sole input, and the service enqueues this on a JMS destination.
Receive, which dequeues a message from a specified JMS destination and return it to the client.

A service can offer both operations, and on any single service you can choose whether the send and receive operation act upon the same JMS destination. In the case where they do not, the send operation will set JMS properties on sent messages that indicate the JMS destination on which responses are expected.

JMS web services can be deployed to Oracle Application Server and Oracle Application Server Containers for J2EE (OC4J). OC4J/JMS is not supported in Oracle9iAS 9.0.3 or OC4J 9.0.3. OJMS is the JMS interface onto Oracle AQ in the database, and it is Oracle's J2EE 1.3 compliant JMS provider.

To run a JMS web service deployed to OC4J 9.0.3 or Oracle9iAS 9.0.3, you should configure OC4J to hand over the JMS implementation to OJMS.
