You are using submit button to trigger your servlet class. When you press submit button a new request object is created and it will not contain your map object.

To resolve this problem you can use session object instead of request object.

Note: Same request object transfer through jsp page to servlet class when you used forward method through them. Pay attention that in your case that is not possible in normal way; because you want to get some info from user and submit button will send them to servlet.
