    Your web.xml and <form> are all perfectly fine. The servlet must be mapped on /servleturl and the form action must point to servleturl.

    The error message also proves that the servlet is perfectly found:

    message HTTP method POST is not supported by this URL

    You would otherwise have gotten a 404 Page Not Found (servlet not found) or maybe worse a 500 Internal Server Error (servlet failed to execute).

    The error you got basically means that there’s no doPost() method. However, your code example do contain it. This can have only one cause: you are not running the servlet class version you think you are running. The one currently deployed does not have the doPost() method. Clean up everything, recompile/rebuild everything, redeploy the webapp, restart the server and try again.
