Asynchronous Web Service

The use of WS-Addressing 1.0 is automatically performed by WebLogic Server when implementing asynchronous web service features.

Buffered oneway operations are implemented by Web Service tier.

With buffered oneway operations, the generic client invokes the service synchronously. Beneath the covers, the synchronous call only completes upon the delivery of the request on the server-side JMS queue. Once the request is delivered successfully to the JMS queue, the client is unblocked and proceeds with its client-side execution. The JMS queue "weblogic.wsee.DefaultQueue" is used by default, although the buffered operation may specify a custom JMS queue if desired.

The oneway annotation @Oneway() marks a web service operation as buffered: the operation must return void. The optional @BufferQueue annotation specifies the JMS Queue used for a buffered operation. Without this annotation, the default queue "weblogic.wsee.DefaultQueue" will be used.

Asynchronous request-response operations are implemented by client tier.

In asynchronous request-response model, the client request is delivered to a client-side asynchronous handler. The Async Handler synchronously invokes the remote operation, and triggers the response handler method in the client to process the response.

The @ServiceClient annotation specifies the variables used to call a desired service asynchronously.
The @AsyncResponse annotation specifies the method to handle a response to an async request.
The @AsyncFailure annotation specifies the method to handle an error from an async request.
