Java and UDP packets / Java rCon Client

[hambeast]

Hey all,

Wondering if there are any java guys out there that could help shed some light on working with UDP and java.

I am referencing this resource: http://www.battleye.com/downloads/BERConProtocol.txt

What I am trying to do is send a UDP login packet (0x00) and receive a response packet back (0x01 or 0x00).

I am trying to follow JAVA tutorials online regarding client/server behavior using UDP but I am not getting to where I want to be.

I am using the following code:

protected static void connect() throws Exception{
String pass = "mypass";
 
DatagramSocket clientSocket = new DatagramSocket();
InetAddress IPAddress = InetAddress.getByName("localhost");
byte[] sendData = new byte[1024];
byte[] receiveData = new byte[1024];
 
String sentence = pass;
 
sendData = sentence.getBytes();
 
DatagramPacket sendPacket = new DatagramPacket(sendData, sendData.length, IPAddress, 2302);
clientSocket.send(sendPacket);
 
DatagramPacket receivePacket = new DatagramPacket(receiveData, receiveData.length);
clientSocket.receive(receivePacket);
 
String modifiedSentence = new String(receivePacket.getData());
System.out.println("FROM SERVER:" + modifiedSentence);
clientSocket.close();
 
 
}

The problem is that when I run a debug, I get stuck at this line with no response:

DatagramPacket receivePacket = new DatagramPacket(receiveData, receiveData.length);

I'm not 100% sure if I am doing this the right way or not and honestly have no idea how to specify the packet address that I am sending.

Any help at all will be greatly appreciated.
