Subject Multiple Cores with Solr Cell for indexing documents
Date Thu, 24 Mar 2011 21:05:08 GMT
Well, there lies the problem--it's not JUST the Tika jar.  If it's not one thing, it's another,
and I'm not even sure which directory Solr actually looks in.  In my Solr.xml file I have
it use a shared library folder for every core.  Since each core will be holding very homologous
data, there's no need to have any different library modules for each.

The relevant line in my solr.xml file is <solr persistent="true" sharedLib="lib">. 
That is housed in .../example/solr/.  So, does it look in .../example/lib or .../example/solr/lib?

Sounds like the Tika jar is not on the class path. Add it to a directory where
Solr's looking for libs.
