Subject: Handling Session Timeout
Hello Gurus
I am trying to handle session timeout by extending RequestProcessor. Since
the processPreprocess(...) method is called before the Action.execute(..)
method, am trying to add that piece of code to check if the session is
valid. The problem am facing is, if i return false from this method, the
requestProcessor will stop processing and return the control back to doGet
or doPost method in ActionServlet. How do I redirect it to login.jsp or
index.jsp from there? Any help/tips would be really great.
Thanx.
Sam

Rather than do this in a subclass of RequestProcessor, I usually
have all my Actions extend a Base action (a base DispatchAction
actually) and in there I override the execute method and do
something like...
public ActionForward execute(final ActionMapping mapping, final
ActionForm form, final HttpServletRequest request, final
HttpServletResponse response) throws Exception {
HttpSession session = request.getSession(false);
if (session == null || session.getAttribute(loggedOut) !=
null ) {
//user doesn't have a session or they loggedOut using the
logout button
return mapping.findForward(Const.GOTO_LOGIN);
} else if ( session.getAttribute(userBean) == null ) {
//user has a session, but no userBean in scope so therefore
session has timed out
ActionMessages messages = new ActionMessages();
messages.add(ActionMessages.GLOBAL_MESSAGE, new
ActionMessage(message.session.expired) );
saveMessages(request, messages);
return mapping.findForward(Const.GOTO_LOGIN);
} else {
//user is already logged in so
//call super class method which will call apropriate
dispatch method in subclass
return super.execute(mapping, form, request, response);
}
}

RE: Handling Session Timeout
People have suggested servlet filter is a good choice
to check session time-out that if I want all servlets
and JSPs remain intact.
I do not have any idea how it works in Struts. First
of all, I think this servlet filter has to be declared
in the web.xml. I have many actions in the struts
application. How do I call this servlet filter
whenever the flow goes to an action? Do I code
HttpSession session = request.getSession( false );
if ( session != null)
{
session.removeAttribut( ... );
session.invalidate();
}
in the doFilter(); ?
