Thanks Erik and Bess.  Erik:  Lamentably, your

java -cp lucene-core-2.0.0.jar:lucene-demos-2.0.0.jar
org.apache.lucene.demo.IndexFiles src/

threw the same error.  I'm going to take a look at the LuceneInAction
codebase and see if I can get it working that way.  Thanks for taking
the time to install 2.0.0.  I don't know how I ended up with 2.0.1
jars--they appeared when I ran ant . . . .

Bess:  Thanks for the advice.  I'm going to give things a whirl this way, too.

Yours,

Andrew
