System and process for communication between Java server pages and servlets

摘要

The present invention addresses the above-described problem by channeling all the communication between JSP and servlets via a single servlet, which delegates to a request and screen flow handlers those objects that are in charge of looking after the details of the user's activities and navigation. The invention provides a Front Controller pattern and uses the servlets based on the Front Controller pattern. The pattern utilizes loose coupling between business processing and screen flow, using HTTP actions that call upon specialized implementations of the handler interfaces. The business processing and screen flow, therefore, can change with no or negligible effect on each other.
