First, I'm no Tomcat expert.... here's the Tomcat Solr
page, but you've probably already seen it:
http://wiki.apache.org/solr/SolrTomcat
But I'm guessing that you may have old jars around
somewhere and things are getting confused. I'd
blow away the whole thing and start over, whenever
I start copying jars around I always lose track of
what's where.
Have you successfully had any other Solr operate
under Tomcat?
Sorry I can't be more help
