How to receive gprs/gps data at server side

[hixiaohui]

Hi, I have a device that records gps locations and sends them to an ip/port pair via gprs. I wrote a simple tcp server at my server, but I couldn't receive any data from that device. I posted the tcp server code below. Any suggestions are appreciated. //TCPServer.java
//TCPServer.java

import java.io.*;
import java.net.*;

class TCPServer
{
public static void main(String argv[]) throws Exception
{
String fromclient;
String toclient;

ServerSocket Server = new ServerSocket (5000);

System.out.println ("TCPServer Waiting for client on port 5000");

while(true)
{
Socket connected = Server.accept();
System.out.println( " THE CLIENT"+" "+
connected.getInetAddress() +":"+connected.getPort()+" IS CONNECTED ");

BufferedReader inFromClient =
new BufferedReader(new InputStreamReader (connected.getInputStream()));

while ( true )
{
fromclient = inFromClient.readLine();

if ( fromclient.equals("q") || fromclient.equals("Q") )
{
connected.close();
break;
}

else
{
System.out.println( "RECIEVED:" + fromclient );
}

}

}
}
}
