cloning DatagramPackets
I have a UDP server implemented. Everytime it gets a packet, it spawns a new thread to handle that client's request and then goes back to listen for more client requests
serverSocket =new DatagramSocket(Global.getRenameServerPort());
byte[] receiveData =newbyte[MESSAGESIZE];
DatagramPacket receivePacket =new DatagramPacket(receiveData, receiveData.length);
DatagramPacket receivePacketClone;
while(true)
{
System.out.println("Rename Server started\n");
serverSocket.receive(receivePacket);// block waiting for request from client
if(DEBUG == 2)
System.out.println("Received a packet from the client");
receivePacketClone = (DatagramPacket)receivePacket.clone();
RenameServerInstance request =new RenameServerInstance(receivePacketClone, DEBUG);
/* Create a new thread that will handle this request */
Thread t =new Thread(request);
/* Start the new thread */
t.start();// throws IllegalThreadStateException
/* Go back and listen for new incoming packets */
}//end while
}
catch(Exception e)
{
System.out.println(e);
}
Should I need to clone the receivePacket before I pass it to RenameServerInstance? If so, how should i do it? I tried calling clone() method on receivePacket but it doesnt work. The error that comes is
D:\DS\DIBSSourceCode\MainDIBS\RenameServer.java:116: clone() has protected access in java.lang.Object
receivePacketClone = (DatagramPacket)receivePacket.clone();
Any help is appreciated
