I have my thread class (which transmits a datagram):

Code:

public class heartbeat extends Thread {

	private int portNum;
	private InetAddress address;
	private int siteNum;


	public heartbeat(InetAddress pAddress, int pPortNum, int pSiteNum)
	{
		portNum = 3001;
		address = pAddress;
		siteNum = pSiteNum;

	}

	public void Run()
	{
		byte[] buf = new byte[256];

		String stringToSend = "[H," + siteNum + "]";
		buf = stringToSend.getBytes();
		System.out.println("Port is " + portNum);

		try {
			DatagramSocket socket = new DatagramSocket(portNum);
			DatagramPacket packet = new DatagramPacket(buf, buf.length, address, portNum);

			while(true)
			{
				System.out.println(stringToSend);
				socket.send(packet);
			}
		} catch (Exception e)
		{ System.exit(0); }

	}

}

and then the following two lines in my main program.

Code:

	  	 heartbeat myHeartbeat = new heartbeat(serverAddr, serverPort, siteID);
	  	 myHeartbeat.start();

It all looks right to me but the thread will not run and I can't see whats wrong with it!! Please help.
