  Tutorial: Process JSPs effectively with JavaBeans

This articles shows your how you can process JSPs effectively with JavaBeans

Tutorial Details:

Transport JSP processing logic into a JavaBean with the Template Method design pattern avaServer Pages (JSP) technology offers many features for easy and quick development of Web applications. However, if you use those features without some planning and structure, your JSP code can quickly become a mix of various HTML tags, JSP tags, and Java code that is difficult to follow, debug, and maintain.
The objective here is to have JSP code that resembles HTML to the greatest possible degree, by moving all processing code into JavaBeans.

The benefit of that approach is that the HTML programmers and graphic designers can do the presentation development (using one of many HTML editors) while you, the Java programmer, can do the programming logic. In addition, the approach makes it easy for you to provide different look and feels for the same Web application.

The framework I'll present here uses the Template Method pattern to enforce common design across the entire application and implement common behavior in each JSP. The common behavior includes, but is not limited to, page state management, common page processing, common error processing, and a mechanism for sharing information between pages. Those are all defined only once, leaving you to deal only with the page-specific details.

I'll present a simple "voting" application as an example of how you can use the framework. You should have basic JSP and Java knowledge, and some UML knowledge is desirable but not mandatory.

Static structure overview

This section gives an overview of the framework core participants, as well the example voting application. Figure 1 shows a UML diagram of the framework's structure:
