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.
