Owkay the library thing worked I had to use the core file. Now another problem arrived.
I found this tut to deal with it: http://tinkerlondon.com/now/2010/09/14/oauth-twitter-and-processing/

But I'm still running into a problem when using the example code on the bottom of this tut. It says:
"The function getOAuthAuthorizedInstance(String,String,AccesToken) does not exist."

import twitter4j.internal.org.json.*;
import twitter4j.internal.logging.*;

String msg = "Automatically posted from Processing";

//copy and paste these from your application in dev.twitter.com
String consumer_key = "key";
String consumer_secret = "key-sec";
String oauth_token = "token";
String oauth_token_secret = "token-sec      ";

color bgcolor = color(255);
long timer;

void setup() {
size(640,480);
}

void draw() {
background(bgcolor);
if (millis()-timer > 2000) bgcolor = color(255);
}

void mousePressed() {
Twitter twitter = new TwitterFactory().getOAuthAuthorizedInstance (consumer_key, consumer_secret, new AccessToken( oauth_token, oauth_token_secret) );
try {
Status st = twitter.updateStatus(msg + " " + second());
println("Successfully updated the status to [" + st.getText() + "].");
bgcolor = color(0,0,255);
timer = millis();
}
catch (TwitterException e) {
println(e.getStatusCode());
}
}
