Central Processor of HTTP Methods. This method gets the model for the users session, extracts the Command Parameters and preforms the command specified in the request. It then redirects or if cookies are used forwards the response to the JSP govened by the new state. If a significant error occurs it should be throwned up to here so that a debug page can be displayed. If a user sees a debug page then that is bad so lets try to find out about it and so we can fix it.

Parameters:

req - HTTP Request

res - HTTP Response

Throws:

java.io.IOException - Description of the Exception
