Use the JMS providers

The JMS providers enable a WSIF service to be invoked through JMS.

The Java Messaging Service (JMS) is an API for transport technology. The mapping to a JMS destination is defined during deployment and maintained by the container.

The JMS destination endpoint for a Web service can be realized in any of the following ways...

• The JMS destination for the queue can be the Web service implementation.

• The JMS destination can be (but is not required to be) associated with a message-driven bean by the EJB container, thereby allowing the message-driven bean to be the Web service implementation.

• (For SOAP over JMS) The JMS destination can unwrap the JMS message and route the SOAP message to a Web service that is implemented as a stateless session bean.

The JMS destination endpoint must respect the interaction model expected by the client and defined by the WSDL. It must return a response if one is required.

When the JMS destination endpoint creates the JMS response message the following rules must be followed...

• The response message must be sent to JMSReplyTo from the incoming request.

• The JMSCorrelationID value of the response message must be set to the JMSMessageID value from the request message.

• The response must be sent with a deliveryMode value equal to the JMSDeliveryMode value of the request message.

• The response must be sent with a priority value equal to the JMSPriority value of the request message.

• The timetolive/JMSExpiration value must be set to a value that equals the JMSExpiration value of the request message.

The client does not see any of these headers. The container receives the JMS message and (for SOAP over JMS) removes the SOAP message to send to the client.
