Re: [equinox-dev] HttpService, Jetty, Session timeout

["Benjamin Schmaus" <benjamin.schmaus@xxxxxxxxx>]

Hi Frank -

I've run into this issue before.  Since the OSGi HTTP service doesn't
support the use of a web.xml file (to the best of my knowledge
anyway), session timeouts can't be set in the standard way.

What I've done to work around this is to use reflection to invoke a
Jetty-specific method for setting session timeouts.

For example:

   public void setSessionTimeout(HttpServlet servlet, int timeoutSeconds) {
       ServletContext sc = servlet.getServletContext();

       Object handler = reflector.invokeMethod(sc,
"getServletHandler", null, null);
       reflector.invokeMethod(
               handler,
               "setSessionInactiveInterval",
               new Class[]{Integer.TYPE},
               new Object[]{new Integer(timeoutSeconds)}
       );
   }

(The 'reflector' object uses the java.lang.reflect API under the hood.)

AOP might be another approach to setting session timeout under Jetty
that's worth investigating.
