---------------------------------------------------------------
I get error when I try to get obj.available(). Also I add the received packet
length to the log. pls refer below code and log after that.
static DatagramSocket socket = new DatagramSocket(9095);
public void myServerMethod() {
socket = new DatagramSocket(9095);
byte[] buf = new byte[100000];
DatagramPacket packet = new DatagramPacket(buf, buf.length);
logger.debug("Packet length "+packet.getLength());
while (true) {
logger.debug ("UDPServer Waiting for client on port
"+socket.getLocalPort());
socket.receive(packet);
logger.debug("Packet length "+packet.getLength());
if (packet.getLength()>0) {
ByteArrayInputStream bis = new
ByteArrayInputStream(packet.getData());
ObjectInputStream obj = new
ObjectInputStream(bis);
LogEvent logEvent = (LogEvent)
obj.readObject();
logger.debug("Got it : " +
logEvent.toString());
logger.debug("after read "+obj.available());
// here we read the obj.available(); and first instance there is an
error throwing.
}
} // end of while
} // end of myServerMethod
Below is the printed log.
