Controller servlet

[aliya sharma]

Hello,
I have a simple application where user enters a part_no to get the contents belonging to that part_no. I have a servlet that passes the parameter to java bean and then shows the result on JSP. I want to update the results when they are shown on the JSP. I know how to do it by creating another servlet for that request, but i want to be able to use my existing servlet. I think that would make my servlet Controller. How do i achieve that. I don't want to use struts as i want to get my basics down before i move on. COuld someone please give me a sample code or a link to tutorial on how to achieve this. Even some pointers to get me started would be greatly appreciated. Thanks for your time.

Hi,
I guess you can do it by invoking the same Servlet from JSP but passing different parameters. You can have a parameter called "action" and based on its value same servlet would perform different processing.

yeah, if we name it then it could be known as command pattern. do some reading on Command Pattern. I hope you will get a clear idea.
