System Elements

basics-4 diagram-2

What's going on in this diagram : Appserver process receives a HTTP request from the SOAP Client at the SOAP service's URL (1) and passes it accordingly to the SOAP servlet (2). The SOAP servlet uses the package-supplied HTTP and SOAP decoding functionality to extract the details of the services call (3 and 4), ie. the method name and method parameters. Once armed with these the SOAP servlet can invoke the method (5 and 6), encode the response (7 and 8) and supply the HTTP response to the HTTP Request handler (9) which in turn replies to the SOAP Client (10). Note that the Servlet Thread box simply indicates what is running in the Servlet's VM.
