Can you post your entire web.xml? You can remove all the servlet,
listener, and security constraint stuff.

Gotcha.

Okay, now I get it. You expect Tomcat to set the cookie's max age to be
NOW + 180 minutes. That's what I'd expect, too.

It does. Assuming that you don't have a misconfiguration and that this
is a Tomcat bug, you ought to be able to get around the problem using a
Filter that looks something like this:
public class SessionCookieMaxAgeFilter
implements Filter
{
public void doFilter(ServletRequest request,
ServletResponse response,
FilterChain chain)
{
if(request instanceof HttpServletRequest)
{
Cookie cookie = getCookie((HttpServletRequest)request));
if(null != cookie)
{
// force the cookie back on the client
cookie.setMaxAge(180);
((HttpServletResponse)response).addCookie(cookie);
}
}
}
private Cookie getCookie(HttpServletRequest request)
{
Cookie[] cookies = request.getCookies();
if(null != cookies)
{
for(int i=0; i<cookies.length; ++i)
{
if("JSESSIONID".equals(cookies[i].getName()))
{
return cookie;
}
}
}
return null;
}
}
Post your configuration and I'll take a look at the code (which may take
some time :)
