Trouble connecting sockets...

Question

hi.
i'm trying to connect to sockets over the internet but everytime i used my computers domain name when setting up the socket on the clients side they do not connect , here is the code im using:
server
ServerSocket serversocket = null;
Socket clientsocket = null;
try {
serversocket = new ServerSocket(4444);
clientsocket.accept();
catch (Exception e) { }
client
Socket clientsocket = null;
try {
clientsocket = new Socket("mydomain", 4444);
catch (Exception e) { }
I'm testing these using the same computer and the only way it will connect is if i use my computers name which is "Craig" as the domain name but when i tested it on two computers it never worked
???

client:
import java.net.*;
import java.io.*;
public class client {
public static void main(String[] ags) {
Socket clientsocket = null;
try {
clientsocket = new Socket(InetAddress.getByName(""), 6795);
System.out.println("Connected");
catch (Exception e) {
System.out.println("error occured: " + e);
server
import java.net.*;
import java.io.*;
public class server {
public static void main(String[] args) {
ServerSocket serversocket = null;
Socket clientsocket = null;
try {
serversocket = new ServerSocket(6795);
System.out.println("Adding new socket to port 6795");
System.out.println("waiting for client...");
clientsocket = serversocket.accept();
System.out.println("connected");
catch (Exception e) {
System.out.println("error occured: " + e);
