create a HTTP server with OS 5.0 Network API (9520)
 

Hi all, I am trying to use OS 5.0 Network API to create socket connection. However I can't use that to connection for my PC,but Smartphone is ok. I always get null when scn.getLocalAddress() invoked. Is it need Signature key ?
My code looks like this
----------------------------------
public void run() {
try {
scn = (ServerSocketConnection) Connector.open("socket://:8080";deviceside=true;interface=wifi");
// Wait for a connection.
setStatus("Wait for a connection.");
while (mTrucking) {
sc = (SocketConnection) scn.acceptAndOpen();
Reader in = new InputStreamReader(sc.openInputStream());
PrintStream out = new PrintStream(sc.openOutputStream());
setStatus("get a connection...");
out.print("HTTP/1.1 200 OK\r\n\r\n");
out.print("hello this is http service test!");
out.close();
in.close();
sc.close();
}
scn.close();

} catch (IOException e) {
setStatus(e.getMessage());
e.printStackTrace();
}
}

I just want to create a connection on a Blackberry to a PC through the Internet for transmitting data. and Blackberry is service ,pc is client , anyone know how to do?
