Hi,

I receive a continuous flow of UDP datagrams on my PC that I would like
to process in a Java program. I wrote the following piece of code but I
can't get any datagram (the .receive() function blocks forever). I
checked with a network sniffer - Ethereal/WireShark - and I could
verify the presence of a continuous UDP flow with valid UDP datagram
headers (destination port: 8081; checksum = 0 (none)).

Could someone help me finding out what I'm doint wrong?

Eric

PS: The piece of code:

public final class UDPClient {
   private static final Logger logger = Logger.getRootLogger();
   static byte[] buffer = new byte[65507];

   public static void main(String[] args) {
       try {
           DatagramSocket ds;
           ds = new DatagramSocket(8081);
           DatagramPacket dpi;
           dpi = new DatagramPacket(new byte[512], 512);
           while(true) {
               ds.receive(dpi);
               logger.info("UDP datagram received from " +
dpi.getAddress() + ":" + dpi.getPort());
           }
       } // end try
       catch (Exception e) {
           System.err.println(e);
       } // end catch
   }
}
