classes -No one is giving answers

I just want to know the advantages of innner classes
and also annonymous inner classes.

Mixing script with applets to communicate with sockets application

Hello,
I hav Written a simple chat application using applet and socket programming.
My application consists of one Applet(Client program) which establishes connection to the server program (standalone application runs on port suppose on 1080).I tested on
my machine It works fine.
So I copied the client applet class file to other machine and tried to establish connection between applet running on other machine and server program running on my machine,but I could not.I got so many exceptions(Security,socket etc) when I excuted applet on other machine
why???
I think my client application needs to be trusted.If so how.
Need urgent help from u.
I want to close connection when the back button on the browser is pressed.is it necessary to use javascript in client program if so help me
