Problem in SNMP4J Installation

Question

Hello everyone,
I'm working on developing an SNMPv3 based NMS software for a Licensed Band cellular Radio Backhaul, using SNMP4J. My major concern in this project is to do both, manager as well as the agent part.
Being a beginner, I'm facing problem with the installation of the software itself.
I downloaded snmp4j-agentx-1.3.1a , currently working on Windows XP platform and trying to execute them over the simple command prompt of Windows (Will be working over Eclipse IDE later).
Since there was no online help available regarding the installation steps of this software, i tried n number of open forums which gave me the idea that certain .jar files were to be executed. However, no matter what i tried, all I got were Class Manifest errors. or, NoClassDef errors. This led to more confusion, resulting in multiple copies of the extracted snmp4j-agentx-1.3.1a folder at various locations. Also, is there a particular sequence in which these files are to be compiled/executed.
I also made a simple test code that should make a PDU and send it successfully. Since i can't execute and check it, i 'm a bit doubtful about it too.

snmp = new Snmp(transport);
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("MD5DES"),
new UsmUser(new OctetString("MD5DES"),
AuthMD5.ID,
new OctetString("MD5DESUserAuthPassword"),
PrivDES.ID,
new OctetString("MD5DESUserPrivPassword")));
// 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("MD5DES"));
// create the PDU
PDU pdu = new ScopedPDU();
pdu.add(new VariableBinding(new OID("1.3.6")));
pdu.setType(PDU.GETNEXT);
// send the PDU
ResponseEvent response = snmp.send(pdu, target);
if(response.getResponse()== NULL)
System.out.println("Request Timed out!!!");
exit();
// extract the response PDU (could be null if timed out)
PDU responsePDU = response.getResponse();
// extract the address used by the agent to send the response:
Address peerAddress = response.getPeerAddress();
}

Hi,
  Client copy is important when your adding Java Addin. The java stack will be on this client only.
Can I perform client copy after J2EE installation?
Yes you can.. create client just say 555 give this client in while adding java addin. It will create another instance. It might not be a problem. If possible, try to delete the java instance refer to the installation gude.
If not, do I need to uninstall and start the installation from the scratch?
In my view not required from scratch
Also Please let me know the procedure for client copy?
Go to Tcode scc4 to create client give the required details if possible all.
Remember the client you created in the above transaction.
Try to login system using the created client number and userid is SAP*
and passwrd is "PASS".
Go to tcode sccl there you have copy the data from which client. Try to give the profile which is mentioned in the installation guide..
