a question about Socket.

[snoopyqhq]

hi all,
I'm newer about the j2me development and knew little about socket.I want to know why the following sentence can't connect to the server;
SocketConnection sc = (SocketConnection)Connector.open("socket://java.sun.com:80");
it always throw a exception:Target port denied to untrusted application.
Thanks for your help.

I know the answer, becasue my computer set wrong subnet mask.
