MaxIdleTime is not changeable for websocket connections in openfire

Hi,

I have installed websocket plugin of openfire. Now when on sparkweb side if a user's networks goes off then on openfire we can still see its presence for 5 minutes after which its presence is offline. When i saw the websocket plugin war file then it uses a xmppservlet which extends websocketServlet . In websocketServlet maxIdleTime is set which websocketServlet gets from int param but i dont see this init param's entry anywhere in any web.xml file

Below is the code snippet of websocketServlet where in init function maxidleTime is set:-

But i dont see the default 5 minutes entry of maxIdleTime in any web.xml

@Override

     public void init() throws ServletException

    {

         try

         {

             String bs = getInitParameter("bufferSize");

             _webSocketFactory = new WebSocketFactory(this, bs == null ? 8192 : Integer.parseInt(bs));

             _webSocketFactory.start();

             String max = getInitParameter("maxIdleTime");

             if (max != null)

                 _webSocketFactory.setMaxIdleTime(Integer.parseInt(max));

             max = getInitParameter("maxTextMessageSize");

             if (max != null)

                 _webSocketFactory.setMaxTextMessageSize(Integer.parseInt(max));

             max = getInitParameter("maxBinaryMessageSize");

             if (max != null)

                 _webSocketFactory.setMaxBinaryMessageSize(Integer.parseInt(max));

             String min = getInitParameter("minVersion");

             if (min != null)

                 _webSocketFactory.setMinVersion(Integer.parseInt(min));

         }

         catch (ServletException x)

         {

             throw x;

         }

         catch (Exception x)

         {

             throw new ServletException(x);

         }

     }

Does anybody has any idea how to set maxIdleTime ??
