Thanks, Matt!

You are indeed correct, sir.  That was a pretty stupid oversight on my part!  The offending lines (the line following the one reported also needed to be modified) have been modified and I no longer get compile errors for that particular code block.

Now I'm getting compile errors in the next block.  Apparently, this is NOT a classpath issue, rather a syntax issue.  That is the good news....

The bad news is that this example is not among those available for download off the O'Reilly site (!) and it looks like I'm going to have to actually RTFM the JDOM API to figure it out. :-)

Here's the offending block, should any of you guys be able to notice what's wrong by eyeballing it (note that this is only my 3rd day teaching myself Java/XML/XSL, so be gentle :-) ):

import org.jdom.*;

[class declaration]
[empty constructor]

public void newDocument( OutputStream out) throws IO,JDOM {

Namespace ns = Namespace.getNamespace("blah", "http://blah.blah.blah");
Document doc = new Document( new Element( "config", ns);

* * *
[repaired code]
* * *

    .addAttribute( "kernel", "2.2.14")
    .addAttribute( new Attribute( "dist", "RedHat 6.1"))
    .addChild( new Element( "gui", ns)
        .setContent( "No Window Manager Installed"))
    .addChild( new Comment( "Sound Card Config"))
    .addChild( new Element( "Sound")
        .addChild( new Comment( "Sound Blaster Card"))
        .addChild( new Element( "card")
            .addChild( new Element( "name")
                .setContent( "Sound Blaster Platinum"))));
    XMLOutputter xo = new XMLOutputter();
    xo.output( doc, out); 

To this, the compiler is whining (in Forte):
    setContent(java.util.List) in org.jdom.Element cannot be applied to (java.lang.String)
.addChild( new Element( "name")

cannot resolve symbol
symbol: method addChild (org.jdom.Comment)
location: class org.jdom.Element
    .addChild( new Element( "sound")

And at the command prompt:
    package org.jdom does not exist

Isn't this fun????  I'll fax a beer to the first gearhead that solves this.
