WSIFOperation interface
You use the WSIFOperation interface to invoke a service, based on a particular binding.
The WSIFOperation interface is the runtime representation of an operation. This interface provides methods to create input, output, and fault messages, and to invoke the operation.
For more information about the WSIFOperation interface, see the generated API documentation that is supplied with WSIF (see the Apache WSIF website).
createInputMessage, createOutputMessage and createFaultMessage
These are factory methods to create the messages required by the invocation methods. All invocation methods require an input message.
executeRequestResponseOperation
This method invokes "In Out" operations.
executeInputOnlyOperation
This method invokes "In only" operations.
executeRequestResponseOperation
If this method is used for invocation, an output and a fault message are instantiated and passed on the call to the method. If the method returns true, the output message contains the response message. If the message returns false, a fault occurred and is returned in the fault message.
executeRequestResponseAsync
This method allows "In Out" operations to be invoked with the reply handled by using an alternative thread. Use of this method is discussed further in WSIFOperation - Asynchronous interactions reference.
setContext and getContext
Use of these methods is discussed in WSIFOperation - Context. All of the executeNnnn methods fail with an exception if there is an error in processing the request in the WSIF provider.
Set the timeouts for synchronous and asynchronous operations is discussed in WSIFOperation - Synchronous and asynchronous timeouts reference.
