Problems with security???

[dush]

hi all

Well I am trying to make a simple chat program with no rooms and
stuff. I got under way wiht some pervious help but now I have built a
sever and client and the thing won't work. I get the following runtime
error message

java.security.AccessControlException: access denied
(java.net.SocketPermission 127.0.0.1:8001 connect,resolve)
at
java.security.AccessControlContext.checkPermission(AccessControlContext.java:272)

at ChatApplet.init(ChatApplet.java:22)
at sun.applet.AppletPanel.run(AppletPanel.java:344)
at java.lang.Thread.run(Thread.java:484)

I will also say that I installed IIS on my computer so I can test the
web page where my applet shoud be.

I will also list the code for the server and the applet:

server:

try {
p.println(message);
}
catch (Exception ex) {
System.out.println("Error in sendToAll:" + ex);
}
}
}
}

private Socket socket;

public ConnectionThread(Socket s, PrintWriter o) {
this.socket = s;
this.out = o;
}

public void run() {

socket.close();
}
catch (Exception e) {
System.out.println("Erroe closing:" + e);
