For an application receiving high-volume traffic, you may want to add buffers to the application's methods and callbacks. When clients call a buffered method, the call is stored in a buffer and the client does not have to wait for the application to handle the call. When an application sends a callback, the message is stored in a buffer and the application does not have to wait until the client processes the callback.
Buffers can be added to web service methods and callbacks and to control methods, provided the control is used within a web service.
Web service buffers are implemented using the weblogic.jws.MessageBuffer annotation.
For more information on adding buffers to web services see Creating Buffered Web Services in the WebLogic Server documentation.
Control buffers are implemented using the com.bea.control.annotations.MessageBuffer annotation.
For more information on adding buffers to controls see com.bea.control.annotations.MessageBuffer.
