Sorry for the confusion.

Also, the code you posted isn't complete, you have not provided the source for the Listener class so I was unable to run the code you posted.

can u please see my code where am going wrong????

package com.lnt.TestApp;

public class Test {

static Address addr = new Address(0, "172.28.14.100");

public Test() {
}

public static void main(String args[]) {
	initializeDevice();
}

public static void initializeDevice() {
	try {

		Thread.sleep(500);

		getObjectList(lDevice, "172.28.14.100",	47808, 0);
	} catch (Exception e) {
		System.out.println("Error : " + e.getMessage());
	} finally {
		closeDevice();
	}
}

public static AcknowledgementService send(LocalDevice d,
		ConfirmedRequestService s) throws Exception {

// Address a = new Address(InetAddrCache.get("localhost", 0xbac1));
return d.send(addr, null, MaxApduLength.UP_TO_1476, Segmentation.segmentedBoth, s);
}

public static void closeDevice() {
	try {
		lDevice.terminate();
	} catch (Exception e) {
		System.out.println(e.getMessage());
	}
}

private static void getObjectList(LocalDevice localDevice, String ip,
		int port, int deviceId) throws Exception {
	for (RemoteDevice d : localDevice.getRemoteDevices()) {

// ObjectIdentifier oid = d.getObjectIdentifier();
@SuppressWarnings("unchecked")
List<ObjectIdentifier> oids = ((SequenceOf<ObjectIdentifier>) RequestUtils
.sendReadPropertyAllowNull(localDevice, d, d.getObjectIdentifier(),PropertyIdentifier.objectList)).getValues();

		for (int i = 0; i < oids.size(); i++) {
			System.out.println("OBjectIdentifier"+oids);
		}
		
		for (ObjectIdentifier oid : oids) {
			
			ReadPropertyRequest read = new ReadPropertyRequest(oid,	PropertyIdentifier.deviceAddressBinding);
			ReadPropertyAck ack = (ReadPropertyAck) localDevice.send(d, read); 
			
			System.out.println("Value: " + ack.getValue());
			

		}
		
	}
}

}

and my optpuit is
Segmentation: both
OBjectIdentifier[Device 9899]
Value: []
OBjectIdentifier[Device 0, Analog Value 1, Analog Value 2, Trend Log 1, Trend Log 2, File 0]
OBjectIdentifier[Device 0, Analog Value 1, Analog Value 2, Trend Log 1, Trend Log 2, File 0]
OBjectIdentifier[Device 0, Analog Value 1, Analog Value 2, Trend Log 1, Trend Log 2, File 0]
OBjectIdentifier[Device 0, Analog Value 1, Analog Value 2, Trend Log 1, Trend Log 2, File 0]
OBjectIdentifier[Device 0, Analog Value 1, Analog Value 2, Trend Log 1, Trend Log 2, File 0]
OBjectIdentifier[Device 0, Analog Value 1, Analog Value 2, Trend Log 1, Trend Log 2, File 0]
but i want analog values form that any hint ???

In your method getObjectList(localDevice, ip, port, deviceId) you may be using the wrong Object Identifier. You are hard coding the deviceId to 17800 but you are requesting the object list for all remote devices that have been discovered. I was able to get your code to work on my test platform by changing the following:

ReadPropertyRequest read = new ReadPropertyRequest(new ObjectIdentifier(ObjectType.device, deviceId), PropertyIdentifier.objectList);

to:

ReadPropertyRequest read = new ReadPropertyRequest(oid,PropertyIdentifier.objectList);

This change ensures that you are using the ObjectIdentifier for the remote devices that have been discovered.
