oops, the lucene 2.4.0 jar was in the jre/lib/ext directory (I don't remember
putting it there). when i updated to lucene 2.4.1 i put the jar in the
tomcat/lib directory (which also had the lucene 2.4.0 jar). i deleted the old
lucene 2.4.0 jar. changing the code to use FSDirectory instead of the index
path string seemed to work though, although it may have blown up if i tested it
more extensively. Sorry for wasting your time.
Sincerely,
Chris Salem

That exception looks like it's from 2.4.0, not 2.4.1.
Can you double check your CLASSPATH?
