a quick workaround for this:
create folders cocoa/library in /sketchbook/libraries
go to System/Library/Java and "create archive of com" (ctrl+mouse click on folder)
a zip file com.jar is created. rename the zip to cocoa.jar
move cocoa.jar to /sketchbook/libraries/cocoa/library
restart processing and run your sketch.

the sketchbook folder refers to the folder in which processing stores your sketches (sketches inside this folder can be accessed in processing's menubar under File->sketchbook).  
on mac this folder is located at
~/Documents/Processing
contributed libraries go into
~/Documents/Processing/libraries

on windows it is located at
~/My Documents/Processing
(e.g. C:\Documents and Settings\username\My Documents\Processing)
contributed libraries go into
~/My Documents/Processing/libraries

it's "libraries" not "library".

~/Documents/Processing/libraries

you should put it there as the app-bundle will be replaced when you upgrade to a newer release.

I tried using the workaround, however, I have no folder named "com" inside System/Library/Java.

Where do i find that thing then?

Since I wrote my last post questioning how one passes Processing variables to AppleScript code I've discovered a few things. I'm just a beginner in Processing and only moderately proficient with AppleScript so my comments below are for beginners. They may be obvious to everyone else (they sure weren't to me). Please correct or call me on anything you might see amiss. I apologize for not being able to include reference URL's here as I wanted but I have not been on the forum long enough.

Using AppleScript in Processing Sketches

1) Add Cocoa foundation library to Processing - use the link elsewhere on this page for directions

2) Add this line at the beginning of your Processing sketch to import the Cocoa library (which will know what to do with the AppleScript code): import com.apple.cocoa.foundation.*;

3) Add your AppleScript code to the void draw() block

4) Start the first line with "String script = ". Example:   String script = "tell application \"Finder\"" + "\n"

5) Start every other AS line with a plus sign (+)

6) Put these lines after your AS code in the void block:
 println(script);
 executeScript(script);}

void executeScript(String script) {
 NSAppleScript myScript = new NSAppleScript(script);
 NSMutableDictionary errors = new NSMutableDictionary();
 myScript.execute(errors);

7) Put quotations around every AS line

8) "Escape" or put a backslash ("\") before every quotation mark (except the beginning and ending marks of each line) in your AS code

9) End every line (what is usually a line in any AppleScript editor) with what's inside these parenthesis (+ "\n")

10) You can put everything on one line or break the lines using point #9 above

11) The last line requires a semicolon (";") at the end

12) I couldn't get conditionals (if something equals/doesn't equal or is greater/lesser than) to work in AppleScript so I used Processing conditionals within the AppleScript code. To do so end that part of your AS code with a quotation mark, add the plus sign, the Processing code, another plus sign and then continue your AS code with a quotation mark. Example:     + "if " + (v_push != 999) + " then tell application \"System Events\" to key code " + v_push + "\n"

13) The draw block automatically loops (at the speed specified by the frameRate line in the setup block). Example:  frameRate(6);

14) If you don't want the draw block to loop add the noLoop(); line in the setup block

15) You have to declare your AS variables in the first part of the sketch. See here for instructions on the Processing site

The Java/Cocoa bridge has been removed by Apple in 10.6. :-( AFAIK you can use the files from 10.5 – or switch to http://code.google.com/p/rococoa/
