Controller(C): The third part, the controller, accepts input and converts it to commands for the model or view.View (V): A view is an output representation of information, such as displaying information or reports to the user either as a text form or as charts.Model (M): This is the central component of MVC, directly managing the application's data, business logic and rules.MVC divides the application into three interconnected part or components, so as to separate the code that create or manage the data from the ways the information is presented to the user. Here, you can add your own email.MVC stands for Model View Controller and it is a web design pattern. The localhost address is: Figure 20: home.jsp after running the application: Now, we will run UserApplication in EclipseIDE. This is implemented by the container by calling the jspInit() method. Now, the JSP container initializes the instantiated object by invoking the init method. After correctly loading it, the JSP container creates an instance of the servlet class. In the third stage, the JSP container loads the servlet generated in the previous two stages. In this stage, the JSP container compiles the java source code in order to create the corresponding servlet and generated class file. Translation is automatically done by the Web server which locates, validates the correctness and writes the servlet for the JSP page. In the first stage, the web container translates the JSP document into an equivalent Java code.

The life cycle is shown in the figure given below: In this step the JSP is compiled into servlet. The JSP life cycle is the same as Servlet life cycle with an additional step.

A JSP page can be accessed directly, whereas Servlet requires mapping with web.xml.

As JSP is handled by the web container for any update in their code, it doesn’t need recompilation like servlets do.

It doesn’t require additional files, like java class file and web.xml.

JSP provides an easier way of creating and managing dynamic web pages.

IDE’s generally used for running JSP pages is NetBeansIDE and EclipseIDE.

The tags are used for retrieving information from the database, sharing information between pages etc. Java code can be inserted in HTML pages by using JSP tags. Java Server Pages (JSP) is used for creating dynamic web pages.
