First off, respect to the creators of this fantastic piece of software. And forgive me if this isn't the right forum for a beginner question like this, please do point me in the right direction.

I'm trying to play around with http://www.aharef.info/static/htmlgraph/sourcecode.html - the first few lines are as follows:

import traer.physics.*;
import traer.animation.*;
import java.util.Iterator;
import java.util.ArrayList;
import java.util.HashMap;
import processing.net.*;
import org.htmlparser.*;
import org.htmlparser.util.*;
import org.htmlparser.filters.*;
import org.htmlparser.nodes.*;

I've found traer.physics and traer.animation and successfully unzipped them into /my documents/processing/libraries and now they appear on the sketch/import library menu when I run processing (in fact, they appear twice, first of all above a divider, then again in with the rest of the libraries, but that doesn't seem to be a problem). I've done exactly the same thing with htmlparser1_6 and it is definitely there in the sketchbook folder, but it doesn't show up in the menu and when I try to run the code, I get the messages "The package org.htmlparser does not exist. You might be missing a library" and "Starting with release 0149, libraries must be installed in a folder named 'libraries' inside the 'sketchbook' folder." Do I need to rename something, or have I got the wrong file altogether, or ... ?

Also, what about the java.util and processing.net.* libraries? Are they automatically included in the processing/java installations or do I have to download something else, and if so, what/where?

Thanks in advance for any help,

this guy is completely right.

why would it say something completely wrong. and why is packaged code not set up this way with the jar files in a code folder?
