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.

What is the difference between networking and servlet in java?

How do you configure servlet and server for servlet chaining?

To configure servlet chaining, you need to set up multiple servlets in your web application, typically defined in the web.xml file or through annotations. Each servlet processes requests and can forward the response to the next servlet in the chain using the RequestDispatcher's forward() method. Ensure that each servlet is mapped to a specific URL pattern, allowing the initial request to reach the first servlet in the chain. Additionally, manage the flow by handling request attributes to pass data between servlets as needed.


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 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.
