In that example there is

1. "form.html" in which we enter the user name and click submit
2. "" - servlet which adds a cookie and transfer the control to a jsp which again takes to another servlet named "".in "checkcookie" we retrieve the cookie.

The problem is in the cookietest,trying to use the request dispatcher.I had saved the "result.jsp" directly under tomcat/webapps

when I use this code

it gives me Null Pointer Exception


results in result.jsp not found.

I checked the parameter name,cookie name and the location of the file.I am unable to locate the problem.Please help.

Thank you very much.Vinal

Note: replaced Cookie with Kookie to post this topic

Why result.jsp is directly inside tomcat/webapps ? it should be somewhere under your application root directory.

Can you access the result.jsp directly by typing it in the browser address bar?

This "RequestDispatcher view=request.getRequestDispatcher("/result.jsp")" is being interpreted relative to the current context root. So, make sure your jsp is in the right place. As already suggested, try putting your jsp at the root of your wepapp.
