Hii,,

I am having a problem doing session management in Struts.....After logging out the user has to be directed to login page. and invalidate the session..This i am doing through logoff action class...Also after logging i need to make sure that user cannot see the contents of jsp page rather be directed to login page...here is m login action class..

In all the action classes i am checking whether the (String)session.getAttribute("loggedin")==true...If not i am redirecting it to login page...This works fine...But in my jsp i am trying the same thing...
