15. What is singleton class? where is it used ?

Answere: Singleton is a design pattern meant to provide one and only one instance of an object. Other objects can get a reference to this instance through a static method (class constructor is kept private). Why do we need one? Sometimes it is necessary, and often sufficient, to create a single instance of a given class. This has advantages in memory management, and for Java, in garbage collection. Moreover, restricting the number of instances may be necessary or desirable for technological or business reasons-for example, we may only want a single instance of a pool of database connections.

16. What is the difference between JSP and Servlets ?

20. What is the difference in using request.getRequestDispatcher() and context.getRequestDispatcher()?

Answere: In request.getRequestDispatcher(path) in order to create it we need to give the relative path of the resource. But in resourcecontext.getRequestDispatcher(path) in order to create it we need to give the absolute path of the resource.

21. How the JSP file will be executed on the Server side ?

Answere: The JSP file is a document contains tags containing Java Code and this document looks like HTML document. This document saved with some name and ended with the extension of .jsp. This document can be copied in to Document Root of the Web Application at the Server side.

The first time the file (*.jsp) is requested, it is compiled into Servlet object and stored in the Server Memory, and the out put is sent back to the requesting Client.

After the first request the from second request onwards Server checks to see whether the *.jsp file has changed. If it has not changed then the Server invokes the previously compiled Servlet object. The JSP ultimately converted into a Servlet object and remains in the Server Memory and managed at Server side like how the manually developed Servlets managed by the Server.

22. What is ActionServlet ?

Answere: The class org.apache.struts.action.ActionServlet is the called the ActionServlet. In the the Jakarta Struts Framework this class plays the role of controller. All the requests to the server goes through the controller. Controller is responsible for handling all the requests.
