[news.eclipse.newcomer] validator not registered

[devries@xxxxxxxxxxxxxxxx (MarkD)]

How to fix an error that gives this message:
'com.tutorial.ValidatePassword' validator id is is not registered.

(Yes -- it says "is is not".)

I'm new to Eclipse and JavaServer Faces.  I'm trying to learn both, and a 
bunch of other things, using the 
"WTP Tutorials - JavaServer Faces Tools Tutorial" found at 
http://www.eclipse.org/webtools/jsf/docs/tutorial/JSFTools_1_0_tutorial.html
(which also occurs in the Eclipse SDK Help).

About two-thirds of the way down it calls for a new validator.  I have, as 
far as I can tell, followed instructions; my code looks like theirs, and 
appears the same in the Project Explorer.

But my validator does not show up in the choices offered when I open 
faces-config.xml.  When I right-click on the login.jsp file that drives 
all this and validate, I get the error above.  When I hover over a 
reference to this validator, I get the same (syntactically-confused) 
message.

I've googled and searched all over for a day, but cannot find even the 
error message, let alone a fix.  Can anyone here help?  Or point me to a 
better place to ask?

FWIW, I'm using Eclipse 3.4.0, Java jdk1.5.0_15, and eventually Tomcat 
5.0.30.

Full boring disclosure: if you look at the tutorial, it spells it 
validatePassword, with a small 'v'.  Got this error (with the small 'v'.)  
Then I deleted that and used "New->Class" to recreate my validate module, 
and it suggested uppercase.  As you see, same error with 'V'.

Thanks,
