[gk]

i have a JSP page.

i want to check whether there is user exists in the session or not

String user=(String)session.getAttribute("user");

if(user==null)

You're probably looking for code such as the following:

response.sendRedirect(redirectURL);

Or perhaps the action <jsp:forward>.

Why not google for more info? Google is good. Google lets you find out
useful information. If I didn't already know the answer I would google
for "jsp forward page" or "jsp redirect".

<%
String user=(String)session.getAttribute("user");
if(user==null) {
%>
<jsp:forward page="/login.jsp"/>
<% } %>

This works.
