Thanks for your reply.  I tried your suggestion of including the .jar files
individually in the classpath, but i didn't have any luck:

[root@localhost ~]# java -cp
/usr/java/default/lib/lucene-core-2.2.0.jar,/usr/java/default/lib/lucene-demos-2.2.0.jar
org.apache.lucene.demo.IndexFiles /opt/lucene/src/
Exception in thread "main" java.lang.NoClassDefFoundError:
org/apache/lucene/demo/IndexFiles

Is there a way to browse or query the included classes to see what's there
and what's missing?
