Hi,

You can use the http session variable in the login.jsp page. When use logs in create a session variable and set its value to yes as shown below:

session.setAttribute("loggedin", "yes");

Now in login page you can get the value of this session in the login page:

String s = session.getAttribute("loggedin");
if(s!=null){
   //Then display login page
}else{
  //Then display welcome page
}

This way you can achieve it.
