Invocation and Execution of Synchronous Web Services
The majority of Web services provided by the enterprise services packages are invoked synchronously.
The following figure shows the execution of a synchronous web service. For the sake of clarity, the Web service consumer and the components of the HTTP Communication Layer are omitted.
Invocation and Execution of Synchronous Web Services
Process
The execution of such a service takes eight steps. Steps one to five deal with dispatching the incoming message, mapping the contained data, and triggering the appropriate Web service proxy. The remaining steps are required to return the Web service result to the service consumer.
Dispatching a request (steps 1–3)
Processing a request (steps 4–5)
Sending a response (steps 6–8)
The steps described are processed in every invocation of a Web service offered by the enterprise services packages.
