we can pass the values to servlet through from HTML Page as follows:-
create a form --> define <form action=Ser>
where Ser is a servlet java class in which we want to retrieve the value.in web-xml in <servlet> tag class name will be defined.
In Ser.java we can retrieve the value by writing as follows:
String login=request.getParameter("login");
