Re: Tika, Solr running under Tomcat 6 on Debian
I would start over from the Solr 1.4.1 binary distribution and follow the instructions on the wiki: http://wiki.apache.org/solr/ExtractingRequestHandler (Java classpath stuff is notoriously difficult, especially when dynamically configured and loaded. I often cannot tell if Java cannot load the class it prints, or if that class requires others.)
