Help client-server

jyciap11

I have a problem with this program. I have to make a connection between server and client. The client, once connected, enter nickname and choose a color, then press the button and I have to save it in a variable (in need) the nickname inserted, but does not work (the name is written on the screen and not saved). How do I?

Moved because "Using Processing" is about questions about the PDE and the installation.

"does not work (the name is written on the screen and not saved)"
On which side? What do you mean by "save in a variable"? Which variable?

jyciap11

my goal is to save your Nickname in a variable. The problem is that the client needs to go to the server name (nickname) but do not know how to do

up :(

double-clicking on the client I run the client opens two windows, but on the server recognizes them as if they were the same client and not two separate, why?: (
