[Asterisk-java-users] get meetme room number

[preetha A. <pre...@gm...>]

Hi,
I am trying to get the meetme room number through manager api by the
following event:

protected *AbstractMeetMeEvent*(java.lang.Object source)

what is the Object source here?how do i use it in manager api?
my code as follows:
import org.asteriskjava.manager.ManagerConnectionFactory;
import org.asteriskjava.manager.response.ManagerResponse;
import org.asteriskjava.manager.event.AbstractMeetMeEvent;
private AbstractMeetMeEvent abstractMeetme;
public void doGet(HttpServletRequest request, HttpServletResponse response)
            throws ServletException, IOException {

String meetMe="21045";
try {

                     ManagerConnectionFactory factory = new
ManagerConnectionFactory(
                    "192.168.x.xxx", "admin", "1234"); //
            this.managerConnection = factory.createManagerConnection();
abstractMeetme.getMeetMe();

            out.println(abstractMeetme);
managerConnection.login();

            // send the originate action and wait for a maximum of 30
seconds
            // for Asterisk
            // to send a reply
            originateResponse =
managerConnection.sendAction(originateAction,
                    30000);
            // and finally log off and disconnect
            managerConnection.logoff();

            out.println("OK");
        } catch (Exception e) {
            out.println("NOT OK");
            e.printStackTrace();

        }

    }
when i run this code i amgetting the null pointer exception in the line :
abstractMeetme.getMeetMe();




Thanks.
