Hi,
I did the same thing to check for an invalidated session. But when session
becomes null, infinite loop is formed
and the output string "Session is null" is getting printed infinite times.
public void doFilter(ServletRequest request, ServletResponse response,
FilterChain chain) throws IOException, ServletException
{
System.out.println("LoginBean.client = " + LoginBean.client);
if (((HttpServletRequest)request).getSession(false) == null &&
(LoginBean.client !=
null))
{
System.out.println("session is null");
((HttpServletResponse)response).sendRedirect("/login.jsf");
}
else
chain.doFilter(request, response);
}
Please suggest where I am doing wrong.
Regards,
Rashmi

Try putting an "else" around the chain.doFilter() as it may be executed
anyway, ie. do the forward _or_ the chain. I presume the illegal state
exception is being caused when there is no session. BTW would you want to
do a forward or a response.sendRedirect() in this circumstance?
