    Default Dealing with DatagramSocket

    Hello guys,

    I have a server receiving new DatagramPackets through DatagramSockets.

    For each received DatagramPacket, I send them to a new thread do to some calc and then I send the reply to client.

    In order to reply to client, I am also sending the instance of DatagramSocket as parameter to this calculator thread, so I can use it to reply to client, but it`s not working.

    Does anyone knows the best way of doing this?

    This is the error I am getting: java.lang.NullPointerException: null buffer || null address

    Thanks a lot!

    Please post the full text of the error message. Be sure the catch block calls the printStackTrace method so you get the line number where the error occurred.
    If you don't understand my response, don't ignore it, ask a question.
