JSP and Servlet Display of text in a text field

Feb 4th, 2007

Hello Friends,
I am trying to learn JSP, Servlets at the moment.

What am trying to do : A simple text field and a button
What should happen : When you click the button a text should appear something which is specified in the code. for example, "Pradeep".

I am really finding it difficult at the moment to actually bring the JSp and Servlet in connection.

Can anyone help me??

It would be great to start of with a problem to be solved an dthen move ahead.

Thanks and Rgds,
Pradeep (KINO)

the button (when activated) submits a post request to the servlet, the servlet sets some information in the http requests and forwards to the JSP.

What part of that don't you get working? It's rather basic...
