[SNMP4J] Not able to generate the Trap

[gaurava.singhal at wipro.com]

Hi,
 
I have written the following program to generate the trap. Can somebody
please point me the problem in the code, as there are no runtime and
compile time error. But I am not able to recieve the trap on another
SNMP listener program.
 
 
 
import java.io.IOException;

snmpNotificationMibObj=new SnmpNotificationMIB();

addNotifTargets(snmpTargetMibObj, snmpNotificationMibObj);

notifOrignator=new NotificationOriginatorImpl(snmp,new VacmMIB(new

/*byte[] b={1,0,1,0};

transport.sendMessage(new UdpAddress("192.168.220.29/162"), b);*/

} catch (IOException e) {

// TODO Auto-generated catch block

e.printStackTrace();

}

}

public static void main(String[]args){

testGen.generateNotification();

}

}
