Anyone have the files/tutorial on adding these files.

I don't have it in my client and i need it for a webclient.

I have the Update.java/ProgressChecker.java

but there's errors when I compile:

Code:
ProgressChecker.java:3: cannot find symbol
symbol: class RSApplet
class ProgressChecker extends RSApplet {
                              ^
ProgressChecker.java:12: cannot find symbol
symbol  : constructor Thread(ProgressChecker)
location: class java.lang.Thread
        Thread thread = new Thread(this);
                        ^
ProgressChecker.java:37: cannot find symbol
symbol  : variable instance
location: class client
                                        client.instance.drawLoadingText(per, per
 != 100 ? "Loading Cache Library " + per + "%" : "Decompressing Code Library..."
);
                                              ^
