ok, thanks! although this is not mentioned on the device documentation! I will try all roads!

yes, thanks for your response please.But, question please, you mean that it is possible to use Socket Object to retrieve the data from Fingerprint attendance machine?! as in my code!?

sure I checked the documentation very well, and I am sure from the port number and IP address are correct! I mean BY "it does not executed with me" It can not read from the device, just connect and wait for response from the device without hope to retrieve the data :( I do not know where is the error in my code :( !!

see update please!

anyone can help me here please :( : Handling Biometric Fingerprint Attendance Device by using Socket (JAVA) Is that possible?! I try with Socket, BUT it does not executed with me! Me Code is:

import java.io.IOException;
import java.io.ObjectInputStream;
import java.io.ObjectOutputStream;
import java.net.Socket;
import java.net.UnknownHostException;

public class Requester {
Socket requestSocket;
ObjectOutputStream out;
ObjectInputStream in;
String message;

Requester() {
}

void run() throws IOException {
try {
// 1. creating a socket to connect to the server
requestSocket = new Socket("192.168.0.19", 4370);
System.out.println("Connected to given host in port 4370");
// 2. get Input and Output streams
in = new ObjectInputStream(requestSocket.getInputStream());
// 3: Communicating with the server
String line;
while (true) {
line = in.readLine();
if (line != null) {
System.out.println(line);
}
}
} catch (UnknownHostException unknownHost) {
System.err.println("You are trying to connect to an unknown host!");

} catch (IOException ioException) {
    ioException.printStackTrace();

} catch (Exception Exception) {
    Exception.printStackTrace();

} finally {
    in.close();
    requestSocket.close();
}

}

void sendMessage(String msg) {
try {
out.writeObject(msg);
out.flush();
System.out.println("client: " + msg);

} catch (IOException ioException) {
    ioException.printStackTrace();
}

}

public static void main(String args[]) throws IOException {
Requester client = new Requester();
client.run();
}
}

f anyone could help me to communicate with the finger print device I will be grateful.
