Ok, I also thought that the instruction from the JTidy page was
non-sensical, but I posted it because it seemed possible that I just
didn't know the meaning.

I suppose that the correct instruction would be:

tidy.setXHTML(boolean); //indicating that a boolean should be passed

I'm not sure what you the point of passing true/false is versus passing
a boolean variable. I tried both true and false, got the same error.
Pardon, I don't follow what you're getting at.

No, it's for personal use.

AHA! at <http://jtidy.sourceforge.net/howto.html> in that method call,
"tidy.setXHTML(boolean);", the "tidy" object is of type Tidy. I've
been doing that method call on an object of type Test16. Ok, that
help's quite a bit, actually. There's no method by that name in
Test16, but (I assume) there is in the Tidy class.

Test16 is the name of the sample code at
<http://sourceforge.net/docman/ display_doc.php?docid=1298&gro
up_id=13153>
Which I've modified very slightly.

//from ControlTidy.java
Test16 aTidy = new Test16();
//better name, changed that line
Test16 aTest16 = new Test16();
//I had tried to make an interface for aTest16, but for right now
//I'm just trying to get a clean compile.

aTidy is then of type Test16. Hmm, that is a bad name, aTidy once was
of type Tidy and I kept the name but changed the type. Thanks for
bringing attention to that, I've renamed it aTest16.

What I'm aiming for is to hardcode the URL (Yahoo/Google/whatever) as
well as where to direct the output, then put all that into a jar. I
put it in a jar, but nothing happens when the jar is executed, so it's
back to the source code for the ControlTidy class.

Here's ControlTidy.java with aTidy changed to aTest16 :
