What is java servlet chaining?
Servlet Chaining means the output of one servlet act as a input to another servlet. Servlet Aliasing allows us to invoke more than one servlet in sequence when the URL is opened with a common servlet alias. The output from first Servlet is sent as input to other Servlet and so on. The Output from the last Servlet is sent back to the browser. The entire process is called Servlet Chaining.
Which one is faster servlet OR jsp?
Servlet is more faster than JSP, but JSP is more convenient than Servlet and JSP is clearly superior, shorter, simple and easier to use. JSP can be perceived as Java in HTML code. JSP require no explicit compilation as like servlets and can keep in the web application server as HTML file. The web application server in turn compile the java code in JSP and load it in its library for future execution. Servlet can be perceived as HTML in Java code. The servlet is the class file, which would be loaded in the web application server as a program. The program output will be directed to the outstream object which in turn direct to the client as HTML elements.
What is the difference between networking and servlet in java?
Networking is a basic action. A servlet in Java is a single part of networking, a single task.
What is the difference between RequestDispatcher.forward and HttpServletResponse.sendRedirect?
In send Redirect whenever the client makes any request it goes to the container, there the container decides whether the concerned servlet can handle the request or not. If not then the servlet decides that the request can be handle by other servlet or jsp. Then the servlet calls the sendRedirect() method of the response object and sends back the response to the browser along with the status code. Then the browser sees the status code and look for that servlet which can now handle the request. Again the browser makes a new request, but with the name of that servlet which can now handle the request and the result will be displayed to you by the browser. In all this process the client is unaware of the processing.
When do you use JSPs as opposed to Servlets?
JSPs and Servlets can be used interchangeably for the most part. In fact, when a JSP is compiled, it is actually turned into a servlet! That being said, there are some guidelines for using servlets over JSPs or vice versa. Here are a couple of examples, but by no means a complete list: Typically, you would use a JSP to display dynamic data, or a form. A Servlet is usually what you would want to use to process a post or a get, especially considering the method that is called when you call a servlet (either doGet or doPost). For more information on this, here is a good article on Servlet and JSP Best Practices: http:/java.sun.com/developer/technicalArticles/javaserverpages/servlets_jsp

Describe the life cycle of servelet?
Each servlet has the same life cycle: * A server loads and initializes the servlet * The servlet handles zero or more client requests * The server removes the servlet (some servers do this step only when they shut down) == When a server loads a servlet, the server runs the servlet's init method. Initialization completes before client requests are handled and before the servlet is destroyed. Even though most servlets are run in multi-threaded servers, servlets have no concurrency issues during servlet initialization. The server calls the init method once, when the server loads the servlet, and will not call the init method again unless the server is reloading the servlet. The server can not reload a servlet until after the server has destroyed the servlet by calling the destroy method. == After initialization, the servlet is able to handle client requests. This part of the servlet life cycle was handled in the previous lesson. == Servlets run until the server are destroys them, for example, at the request of a system administrator. When a server destroys a servlet, the server runs the servlet's destroy method. The method is run once; the server will not run that servlet again until after the server reloads and reinitializes the servlet. When the destroy method runs, another thread might be running a service request. The Handling Service Threads at Servlet Termination lesson shows you how to provide a clean shutdown when there could be long-running threads still running service requests.

Difference between temporary servlet and permanent servlet?
A temporary servlet is started when a request arrives and shut down after the response is generated. A permanent servlet is loaded when the server is started and lives until the server is shut down. * This is useful when startup costs are high, such as a servlet that establishes a connection to a database. * Also useful for permanent serverside service, such as an RMI server. * Provides faster response to client requests when this is crucial. Being temporary or permanent is part of the server configuration.
