One example that I have gone across is there was a servlet. Some parameter is passed to servlet from JSP using request object. According to that parameter, servlet decide on which JSP request is to be forwarded. Then servlet uses requestDispatcher. This Servlet is said to be a controller servlet.
Now the thing is when JSP is itself having parameter then why in the jsp, based on that parameter, it is not decided what will be next JSP that is to be called. I could not get why servlet was used here. Any suggestions. Or anybody if has used can explain where they have used, so that we can analyse it.
