Struts—— an opensource MVC implementation Malcolm Davis This article introduces Struts, a ModelViewController implementation that uses servlets and JavaServer Pages (JSP) technology. Struts can help you control change in your Web project and promote specialization. Even if you never implement a system with Struts, you may get some ideas for your future servlets and JSP page implementation. Introduction Kids in grade school put HTML pages on the Inter. However, there is a monumental difference between a grade school page and a professionally developed Web site. The page designer (or HTML developer) must understand colors, the customer, product flow, page layout, browser patibility, image creation, JavaScript, and more. Putting a great looking site together takes a lot of work, and most Java developers are more interested in creating a great looking object interface than a user interface. JavaServer Pages (JSP) technology provides the glue between the page designer and the Java developer. If you have worked on a largescale Web application, you understand the term change. ModelViewController (MVC) is a design pattern put together to help control change. MVC decouples interface from business logic and data. Struts is an MVC implementation that uses Servlets and JSP tags, from the J2EE specifications, as part of the implementation. You may never implement a system with Struts, but looking at Struts may give you some ideas on your future Servlets and JSP implementations. ModelViewController (MVC) JSP tags solved only part of our problem. We still have issues with validation, flow control, and updating the state of the application. This is where MVC es to the rescue. MVC helps resolve some of the issues with the single module approach by dividing the problem into three categories: ? Model The model contains the core of the application39。s projected begins, From go into live registry to keep to till the last check out close book, The whole process should take guest as a centre, Provide fast and convenient service, Give the guest the enjoyment of the supremacy of a kind of shopper, only to enhance the level of hotel management, simplify a various of plicated operation, at most the shortest sound of time inside, plete the specification operation of traffic in the hotel, only by that, the passenger can fell fortable and unfettable.
