In this case, although the stubs connect to different Web Services, each Web Service must have a similarly named method, because the Web Services runtime relies on the name of the method ( on MethodName AsyncFailure) to determine how to handle the asynchronous failure, rather than the annotation. The only time you would not use this annotation is if you want a single method to handle failures for two or more stubs that invoke different Web Services. Typically, you always use the annotation to explicitly specify the method that handles asynchronous operation failures. Within the method itself you can get more information about the method failure from the context, and query the specific type of exception and act accordingly. Have two parameters: the asynchronous post-call context (contained in the object) and the Throwable exception, potentially thrown by the asynchronous operation call.Where getQuote is the non-asynchronous name of the method, apc is the asynchronous pre-call context, and symbol is the usual parameter to the getQuote operation. The method that handles the asynchronous failure must follow these guidelines: The stub is the one that has been annotation with the annotation. The annotation takes two parameters: the name of the stub for the Web Service you are invoking and the name of the operation that you are invoking asynchronously.
Use the annotation to specify the method in the JWS file that will handle the potential failure of an asynchronous operation invocation. Because the operation invocation did not wait for a response, a separate method in the JWS file must handle the response when it does finally return similarly, another method must handle a potential failure. When you invoke, from within a JWS file, a Web Service operation asynchronously, the response (or exception, in the case of a failure) does not return immediately after the operation invocation, but rather, at some later point in time. Specifies the method that handles a potential failure when the main JWS file invokes an operation of another Web Service asynchronously.
