If you’re specifying a relative URL as form action, i.e. without the http:// scheme, then it becomes relative to the current URL as you see in your webbrowser’s address bar. It’s thus absolutely not relative to the JSP/HTML file location in server’s WAR folder structure as many starters seem to think.
