JAXB is discussed in the context of bi-directional mapping between XML and Java. A generic web project is developed for PDF and Excel spread sheet reports. JavaServer Faces, the most commonly used view component in web applications is discussed for developing a data table. Facelets, which was integrated into JSF with 2.0 version is discussed in the context of templating. ADF Faces components are used to develop another user interface (UI) application.

Creating a servlet

In this section, we shall create a servlet to process the AJAX request and send a server response. A servlet represents the Controller facet of the Model View Controller (MVC) design pattern; the JSP page represents the View facet. Go to File | New | Other and in the New wizard, expand Web and select Servlet. Click on Next as shown in the following screenshot:

In Create Servlet, select the project EclipseAjax in which you want to create a servlet, select the Source folder as /EclipseAjax/src, specify a Java package name as ajax.servlet and a Class name as FormServlet. A servlet extends the javax.servlet.http.HttpServlet class. Click on Next as shown in the following screenshot:

The URL mappings get specified as /FormServlet, which is based on the servlet name. Click on Next as shown in the following screenshot:

Select the default Modifiers, Interfaces, and method stubs, which include the doGet and doPost by default. Click on Finish as shown in the following screenshot...
