instead of

String txtEmail=request.getParameter("txtEmail");

Answer 1

You have to address the name Attribute of your input Elements Serverside. So if you would have <input type="text" name="username" id="userelementid"> then you would still use request.getParameter("username")

Answer 2

getParameter() method looks for the name attribute as your email input has the name email so you have to use request.getParameter("email");

txtEmail is an id so if you use String txtEmail=request.getParameter("txtEmail");

then you will get txtEmail=null
