Servlet Chaining pages using RequestDispatcher By candid | Posted : Dec 6, 2015 | Updated : Dec 6, 2015
A RequestDispatcher object can be used to forward a request to the resource or to include the resource in a response. The resource can be dynamic or static.
The pathname specified may be relative, although it cannot access outside the current application. This method returns null if the servlet container cannot return a RequestDispatcher.
Forward Forwards a request from a servlet to another resource (servlet or JSP file) on the server. We can use one servlet to do preliminary processing of a request and another resource to generate the output response. Any response from the first servlet will be automatically cleared before forwarding to second servlet. The forwared Servlet will be using the same request and response object send by first servlet.
Include Includes the content of a resource (servlet or JSP page) in the response. In essence, this method enables programmatic server-side includes. The included servlet cannot change the response status code or set headers of first servlet, any attempt to make a change is ignored.
