Comunications between classes

Hello, i have a big problem...

I have two classes:
socketIRC (java pure class)
guiControl (cocoa - java...instanced from IB)

GuiControl have one outlet and one action:
NSTextField label;
OpenConnection();

I would to set a string value to label (.setStringValue()) from class socketIRC (i have instanced this class inside the guicontrol class from the openconnection method) to the guiControl class.
I have tried to do it but an error like this: "non static context...". Now i set the NSTextField to public static. But another error, this time at the runtime. When i try to set the value: "java.lang.NullPointerException".
Now my question is: how can i set a value of an object inside a class, from another class?

And... my socketIRC class have a while(1) (until the end of execution) that read the socket buffer for new data incoming. But if i try to run the class, i can't do anything more... how can i run this process in background? (i have instanced the object: socketIRC x = new socketIRC(); x.main();).

Thx a lot, malcom
