The <form> element in your HTML sends a request to the server. That's "a" request -- one single request. This request should be directed to a servlet which validates and handles the form parameters, not to a JSP.

If the <form> element has type="post" then the doPost() method of the servlet will be called, and if it has type="get" then the doGet() method will be called. Your design should choose the type parameter appropriately.

So that means that the servlet which the <form> element requests should have code in either doPost() or doGet() to handle the request, but not in both of them.

Keeping the nature of the error a secret is not a good way to get help on it.
