session variables

Hi

I have a jsp login page with a basic structure of:

  Enter password and userName
 
  if (password == password in data base){
      set session variable
  }

  if session variable set{
     display menu of site links
  }
Could someone please explain how you set the session variable.  And check for it in this and other site pages.....

Many Thanks in advance

if (password == password in data base)
     session.setAttribute("isLogin", true);

and in the other pages do:

if(session.getValue("isLogin") == null)
   response.sendRedirect("login.html");

Hope that helps!

oh sorry true is boolean :)
So try this:

String isLogin="ok";
if (password == password in data base)
    session.setAttribute("isLogin", isLogin);

and in the other pages do:

if(session.getValue("isLogin") == null)
  response.sendRedirect("login.html");

session.getValue is deprecated. your need
session.getAttribute(), it also may be easier to save username in the session so you can check who is logged on later:
session.setAttribute( "loginUser", username )
if( session.getAttribute( "loginUser" ) != null )
you can also retrieve back username in other page:

String username = (String) session.getAttribute( "loginUser" );
