It is common in web applications to pass data or parameters from one to another page. To retrieve the values of various elements in a HTML form or from another page, we can use the following methods which are available in HttpServletRequest object: String getParameter(String name) Enumeration getParameterNames() String getParamterValues(String name) Following example demonstrates retrieving data from a login page to a servlet: login.html 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 <!DOCTYPE html PUBLIC “-//W3C//DTD HTML 4.01 Transitional//EN” “http://ift.tt/2ewFFOU; <html> <head> <meta http-equiv=“Content-Type” content=“text/html; charset=ISO-8859-1”> <title>Login</title> </head> <body> <form action=“auth.html” method=“get”>
