At runtime, the client application assembles a SOAP message that describes the Web service it wants to invoke. The client sends the message over HTTP to OC4J, which invokes the Web service and responds to the client. Oracle Application Server supports two invocation models:
-
Static Invocation: The client application invokes the Web service through proxy stubs that encapsulate SOAP requests.
-
Dynamic Invocation: The client application creates SOAP requests dynamically from WSDL at runtime to invoke Web services. This requires no proxy stubs.
