Hi
First of all u should have an login page desined alreday or u can design it
by but a tow text field in it
then in html file u will see FORM tag , in FORM tag and exactly in Action
property write this statement for example
<form method="POST" action="Login.jsp">
where Login.jsp is the file u write ur code in it to specify that is the
user name and password is correct or not
and this is some code to see it.
<BODY>
<jsp:useBean id="Process" class ="Card_ST.Process" scope="request">
<%
String userName = request.getParameter("username"); // and be care
the username is the name of text field in first page
String password = request.getParameter("Pass"); // and also here
pass is the name for the second text field
boolean flag;
flag = Process.verifyUser(userName,password); // there are method
in Process.java file called
if (! flag) {
%>
<jsp:forward page="Error.jsp" /> // so if the method return false
so username and password is wrong and this statement forward the user to any
error page
<% }
else
%>
<jsp:forward page="Card.jsp" /> // this is if method return true ,
forward user to any page u want also
</jsp:useBean>
</BODY>
any Q u can ask again
