[SNMP4J] Unknown engine ID

[Marcel Bassuener]

Hi,
I have a problem. I wrote an SNMP Agent, which works (I tested it with 
an other programm).  But now I tried to write my own manager and send 
messages. Every time I start it the agent says: (Unknown engine ID)

3283585 [DefaultUDPTransportMapping_127.0.0.1/161] DEBUG

Here my code:

Snmp snmp =  new Snmp(new DefaultUdpTransportMapping());

         OctetString localEngineID = new 
OctetString(MPv3.createLocalEngineID());

         ((MPv3)snmp.getMessageProcessingModel(MPv3.ID)).
             setLocalEngineID(localEngineID.getValue());

         USM usm = new USM(SecurityProtocols.getInstance(),
                             localEngineID,
                             0);
           SecurityModels.getInstance().addSecurityModel(usm);
           snmp.getUSM().addUser(new OctetString("SHADES"),new 
UsmUser(new OctetString("SHADES"),
                   AuthSHA.ID,
                   new OctetString("SHADESAuthPassword"),
                   PrivDES.ID,
                   new OctetString("SHADESPrivPassword")));

         UserTarget target = new UserTarget();
         target.setSecurityLevel(SecurityLevel.AUTH_PRIV);
         target.setSecurityName(new OctetString("SHADES"));
         target.setVersion(SnmpConstants.version3);
         target.setAddress(new UdpAddress("127.0.0.1/161"));
         target.setRetries(1);
         target.setTimeout(500);
//        target.setMaxSizeRequestPDU(maxSizeResponsePDU);
         snmp.listen();

         ScopedPDU request = new ScopedPDU();
         request.setType(PDU.GET);//createPDU(target);
         if (request.getType() == PDU.GETBULK) {
           request.setMaxRepetitions(50);
           request.setNonRepeaters(1);
         }
         request.add(new VariableBinding(new OID("0.1.0")));

         PDU response = null;
           ResponseEvent responseEvent;
           long startTime = System.currentTimeMillis();
           responseEvent = snmp.send(request, target);
           if (responseEvent != null) {
             response = responseEvent.getResponse();
             System.out.println("Received response after "+
                                (System.currentTimeMillis()-startTime)+" 
millis"+response.getVariableBindings());
         }
         snmp.close();

Please help me!!

Thanks and Best regards
