[Swarm-Support] Swarm Suppport for Exceptions

[durga bhavani]

Hello

 

I am not sure why I am getting this kind of Exceptions

 

 

Exception in thread "main" java.lang.NullPointerException

                         at GroupModelSwarm.activateIn(GroupModelSwarm.java:215)

                         at GroupObserver.activateIn(GroupObserver.java:316)

                         at StartSim.main(StartSim.java:19)

 

This part from GroupmodelSwarm is throwing Exception

  public Activity activateIn (Swarm swarmContext)
        {
                super.activateIn (swarmContext);
                modelSchedule.activateIn (this);
                modelActions.activateIn(this);
                return getActivity ();
        }
 

This part from GroupObserverswarm is throwing Exception

   public Activity activateIn (Swarm swarmContext)
        {
                super.activateIn (swarmContext);
                groupModelSwarm.activateIn (this);
                displaySchedule.activateIn (this);
                return getActivity();
        }
This part from main is throwing Exception

  Globals.env.initSwarm ("Simulation of Work Group Using Swarm", "0.3.1",
"address@hidden", args);
      GroupObserver topLevelSwarm = new GroupObserver (Globals.env.globalZone);
        Swarm swarm = new GroupModelSwarm(Globals.env.globalZone);
        Globals.env.setWindowGeometryRecordName (topLevelSwarm, "topLevelSwarm");
      topLevelSwarm.buildObjects();
      topLevelSwarm.buildActions();
      topLevelSwarm.activateIn(null);
      topLevelSwarm.go ();
      topLevelSwarm.drop ();
    }

 

Someone please tell me why it is throwing exceptions

 

Thanks

Durga
