[SNMP4J] trap notification

[Jose Ignacio]

I'm using the following code to send v2 traps, but it isn't ok at all.
Because with iReasoning Trap Receiver i can't watch trap details.

    public void sendV2 ()
        throws IOException
    {
        TransportMapping transport;
        transport = new DefaultUdpTransportMapping();
        Snmp snmp = new Snmp(transport);

        PDU pdu = new PDU();
        pdu.setType(PDU.TRAP);
        pdu.setMaxRepetitions(2);
        //Trap OID
        pdu.add(new VariableBinding(SnmpConstants.snmpTrapOID, new OID("
1.3.6.1.4.1.9999.1.3.1")));
        //Enterprises.Sainco.TRAPOID
        pdu.add(new VariableBinding(SnmpConstants.snmpTrapEnterprise, new
OID("1.3.6.1.4.1.9999.1.3.1")));
        pdu.add(new VariableBinding(SnmpConstants.snmpTrapAddress));
        pdu.add(new VariableBinding(SnmpConstants.snmpTrapCommunity,new
OctetString("public")));

        pdu.add(new VariableBinding(new OID(".1.3.6.1.4.1.9999.1.2.1.0"),new
OctetString("p1")));
        pdu.add(new VariableBinding(new OID(".1.3.6.1.4.1.9999.1.2.2.0"),new
OctetString("p2")));

        // setting up target
        Address targetAddress = GenericAddress.parse("udp:127.0.0.1/162");
        CommunityTarget target = new CommunityTarget();
        target.setCommunity(new OctetString(mCommunity));
        target.setAddress(targetAddress);
        target.setRetries(mRetries);
        target.setTimeout(mTimeOut);
        target.setVersion(SnmpConstants.version2c);

        ResponseEvent response = snmp.send(pdu, target,transport);
        System.out.println("pdu:" + pdu);
        System.out.println("response:" + response);

        snmp.close();
    }
