Networking with CLDC devices

Question

Hi,
I need a bit of help with converting the program below to CLDC. Essentially, I'll blush if you could suggest a way to do; InetAddress.getLocalHost(); getHostName(); InetAddress.getByName
Thanks
import java.net.*;
class TranslateAddress_App1
public static void main (String args[])
// Look for command line argument
if( args.length != 1){
System.out.println("Error! No IP or Host name");
System.out.println(
"Usage: java TranslateAddress www.ibm.com");
System.out.println(
" or java TranslateAddress 192.168.1.1");
System.exit(0);
try
// When the argument passed is:
// a web URL (e.g. ibm.com), the IP address is
// returned a IP addresss, only the IP address is
// returned.
InetAddress address =
InetAddress.getByName(args[0]);
System.out.println(
"Address " + args[0] + " = " + address);
// To get the hostname when passed an IP address use
// getHostName(), which will return the host name
// string.
System.out.println("Name of " + args[0] + " = " +
address.getHostName());
catch (UnknownHostException e)
System.out.println("Unable to translate address.");

There is no spec'ed way to do this on CLDC. Some vendors may offer OEM specific packages to address this but I haven't seen any. The Generic Connection Framework was designed not to require a TCP/IP stack to perform HTTP and therefore does not require InetAddress type functionality.
