What is the best way to find out your IP address?

[camroe]

I have a Nokia 9500 and want to find out what my IP address is. I wrote this piece of code on and it runs on the emulator (and gives me the correct IP),but only gives me 127.0.0.1 on the phone. I suspect that since the PC is "always on", that the server socket has available to it the IP address before you do an 'serverSocket.acceptAndOpen()'. Is this true?

By the way, I don't really want to do an serverSocket.acceptAndOpen(), because I have no intention of ever connecting to that port, I just want to find out what my IP is.

public static String getIP() {

String returnValue = "";
ServerSocketConnection socket = null;
try {
socket = (ServerSocketConnection) Connector.open("socket://:",Connector.READ_WRITE,false);
if (socket == null) {
System.out.println("Socket is Null");
System.exit( -1);
}
System.out.println("3");
returnValue = socket.getLocalAddress();
System.out.println("Return Value: " + returnValue);
socket.close();
} catch (IOException ex) {
System.out.println("Exception raised by Network.getIP()");
ex.printStackTrace();
} finally {
try {
if (socket != null) {
socket.close();
}
} catch (Exception ex) {
ex.printStackTrace();
}
}
return returnValue;
}
}

Thanks for the info, unfortunately it is all based on C++ calls. Is there anything in Java that is similar?

I took a look at the C++ code and got a similar piece of Java code to compile but I keep getting the exception

"Exception: Target port denied to untrusted applications"

I've used port 80,8082 and 8080 and am loathe to start 'guessing' which ports are trusted or not. I suspect that all of them are are 'denied'.

The code is as follows. I attached the permissions
javax.microedition.io.Connector.serversocket, javax.microedition.io.Connector.socket, javax.microedition.io.Connector.datagramreceiver, javax.microedition.io.Connector.datagram, javax.microedition.io.Connector.comm, javax.microedition.io.Connector.http

to the .jad file. Probably overkill but what the heck.


import javax.microedition.io.Connector;
import javax.microedition.io.SocketConnection;
