Problems with compiling the BlackJackServer program

Question

hello.
this is james mcfadden. I have developed a multiplayer BlackJack card game in Java. the game consists of six programs: BlackJack.java, BlackJackServer.java, BlackJackClient.java, Card.java, Deck.java, and Hand.java. i got most of the game code from http://www.netsoc.tcd.ie/~duncan/dev/java/games/blackjack/. When i compile the server i get the following errors (i've also included the source code in this message):
----jGRASP exec: javac -g X:\NETPROG\Assignment2\BlackJackServer.java
BlackJackServer.java:56: cannot find symbol
symbol : method getSource()
location: class BlackJack
bj.getSource();
^
BlackJack.java:176: cannot find symbol
symbol : method getCodeBase()
location: class BlackJack
card_images[current_card_loading]=getImage(getCodeBase(),"cards/"+(current_card_loading+1)+".gif");
^
BlackJack.java:197: cannot find symbol
symbol : constructor Deck(BlackJack,java.awt.Image[])
location: class Deck
deck=new Deck(this,card_images);//Create a new deck object
^
3 errors
----jGRASP wedge2: exit code for process is 1.
----jGRASP: operation complete.
how do i go about fixing these errors?

Why are you posting this yet again after I told you what the problem was 2 days ago:

Nobody likes to repeat themselves, nor what others have already told you.
