Main Success Scenario (MSS)

Step Action
1 Client submits request to web server.
2 Web server transfers request to container, and container transfers request to framework's dispatcher.
3 Dispatcher consults the mappings to select the appropriate action and creates a context for the request.
4 Dispatcher creates and invokes a proxy to execute the action and its Interceptors.
5 The proxy manages the action pre-process, the procedess, and the post-process.
6 The invocation calls each interceptor in turn before executing the action.
7 Each interceptor affects the request as appropriate.
8 The action handles the transaction corresponding to the request.
9 The action returns a code indicating the appropriate result.
0 The invocation executes the result.
