[SNMP4J] (no subject)

[RobertoBouza at bayviewfinancial.com]

Hello everyone,

I'm getting this Exception:

org.snmp4j.transport.UnsupportedAddressClassException: Unsupported address 
class (transport mapping): org.snmp4j.smi.IpAddress

I'm pretty new to SNMP and developing using SNMP4J. I just want to make a 
SNMP get of an OID variable from a server and I get this error when the 
send methos is called on the snmp class. Here is the code:

Any help would be really appreciated.

public class GetMIBValue {

        public static void  main(String arg[]) {

                try {

                TransportMapping transport = new 
DefaultTcpTransportMapping();
                Snmp snmp = new Snmp(transport);

                // Since we are using SNMPv3 we use authenticated users 
this is handled by the UsmUser and USM class
                UsmUser uu = new UsmUser(new OctetString("ssnmpreader"), 
AuthMD5.ID, new OctetString("ssnmpread3r"), PrivDES.ID, new 
OctetString("ssnmpread3r"));

                if (uu == null) {
                        System.out.println("Null UsmUser");
                } else {
                        System.out.println("Valid UsmUser");
                }

                USM usm = snmp.getUSM();

                if (usm == null) {
                        System.out.println("Null Usm");
                } else {
                        usm = new USM(SecurityProtocols.getInstance(), new 
OctetString(MPv3.createLocalEngineID()), 0);
                        usm.addUser(new OctetString("ssnmpreader"), uu);
                        System.out.println("Valid Usm");
                }

                UserTarget target = new UserTarget();
                IpAddress ipa = new IpAddress("10.10.32.201");
                target.setAddress(ipa); 

                if (target.getAddress().isValid()) {
                        System.out.println("Valid IP address");
                } else {
                        System.out.println("Invalid IP address");
                }

                target.setRetries(1);

                // set timeout to 500 milliseconds -> 2*500ms = 1s total 
timeout
                target.setTimeout(500);
                target.setVersion(SnmpConstants.version3);
                target.setSecurityLevel(SecurityLevel.AUTH_PRIV);
                target.setSecurityName(new OctetString("MD5DES"));

                // We create the basic PDU Unit
                ScopedPDU pdu = new ScopedPDU();
                pdu.add(new VariableBinding(new OID("1.3.6.1.2.1.1.1")));
                pdu.setType(PDU.GET);

                // set non-default context engine ID (to use targets 
authoritative engine ID
                // use an empty (size == 0) octet string)
                pdu.setContextEngineID(new 
OctetString("0x80001f88803d4bf37386c41346"));

                ResponseEvent response = snmp.send(pdu, target);

                PDU responsePDU = response.getResponse();

         if (responsePDU == null) {
                } else {
                        System.out.println("Received response from: "+ 
response.getPeerAddress());
                        System.out.println(responsePDU.toString());
                }

                } catch (Exception exp) {
                        System.out.println(exp.toString());
                        System.out.println("-----------");
                        exp.printStackTrace();
                }
        }
