"Cannot find symbol" error involving JDOM

I am getting a "cannot find symbol" compiler error on:

XMLOutputter outputter = new XMLOutputter(" ", true);

Using the following code:

<pre>
<code>
import org.jdom.*;
import org.jdom.output.XMLOutputter;

public class Stuff {
    public static void main(String[] args) {
        // Task: Create a new Document that has no
        // DocType, but a root element named "rootBeer."
        // The root element will have two child elements,
        // named "Foo" and "Bar."
        // Each element will have the text "Look at me."

        Element root = new Element("rootBeer");
        Document doc = new Document(root);

        Element foo = new Element("Foo");
        foo.setText("Look at me.");
        root.addContent(foo);

        Element bar = new Element("Bar");
        bar.setText("Look at me.");
        root.addContent(bar);

        try{
            XMLOutputter outputter = new XMLOutputter(" ", true);
            outputter.output(doc, System.out);
        } catch (java.io.IOException e){
            e.printStackTrace();
        }
    }
}
</code>
</pre>

I have installed jdom.jar as a library within NetBeans 5.5 IDE and it
seems to recognize JDOM, but according to this site:

http://www.topxml.com/tutorials/main.asp?id=jdom&page=8

This should be valid syntax and yet I am getting this error. What
else should I be doing?

Thanx
