[SNMP4J] SNMP4J set question

[Mauricio Reyes]

Hello,

I am trying to do a set operation from within the code, but I'm getting this 
error message:

C:\Documents and Settings\Test\Desktop\tmp\snmp4jset>java -classpath

jar;./log4j-1.2.7.jar SNMP4JSet

SET sent succesfully

C:\Documents and Settings\Test\Desktop\tmp\snmp4jset>

And the request is not sent.

I'm doing this within the code:

import org.snmp4j.*;
import org.snmp4j.mp.*;
import org.snmp4j.security.*;
import org.snmp4j.smi.*;
import org.snmp4j.transport.*;
import org.snmp4j.util.*;
import org.snmp4j.event.ResponseEvent;

public class SNMP4JSet
{
	public SNMP4JSet()
	{

	}

	public static void main(String[] args)
	{

		try
		{
			int pduType = PDU.SET;
			SNMP4JSet set=new SNMP4JSet();
			Address targetAddress = GenericAddress.parse("127.0.0.1/161");
			TransportMapping transport = new DefaultUdpTransportMapping();
	        	Snmp snmp =  new Snmp(transport);
		      MPv3 mpv3 = 
(MPv3)snmp.getMessageProcessingModel(MessageProcessingModel.MPv3);
	        	USM usm = new USM(SecurityProtocols.getInstance(),new 
OctetString(mpv3.createLocalEngineID()), 0);
	        	SecurityModels.getInstance().addSecurityModel(usm);
	        	transport.listen();

			// add user to the USM
		   	snmp.getUSM().addUser(new OctetString("martest"),
	                         new UsmUser(new OctetString("martest"),
	                                     AuthMD5.ID,
	                                     new OctetString("marprueba"),
	                                     PrivDES.ID,
	                                     new OctetString("marprueba")));
			// create the target
			UserTarget target = new UserTarget();
			target.setAddress(targetAddress);
			target.setRetries(1);
			target.setTimeout(5000);
			target.setVersion(SnmpConstants.version3);
			target.setSecurityLevel(SecurityLevel.AUTH_PRIV);
			target.setSecurityName(new OctetString("marprueba"));

			// create the PDU
			PDU pdu = new ScopedPDU();
			VariableBinding vb = new VariableBinding(new 
OID("1.3.6.1.4.1.1.1.1.10.0"));
			Variable variable;
			variable = new Integer32(Integer.parseInt("27"));
			vb.setVariable(variable);
			pdu.add(vb);
			pdu.setType(PDU.SET);

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

			if(pduType == PDU.SET)
		      {
	          		System.out.println(PDU.getTypeString(pduType) + " sent 
succesfully");
	        	}
		}
		catch(Exception e)
		{
			e.printStackTrace();
		}
	}
}

I don't know what I'm doing wrong. I must be missing something as it works 
fine with the tool provided. I'm trying to send the set operation to a 
net-snmp agent.

Thanks a lot for your collaboration.

Mauricio
