Hmm I've tried starting Solr with no Lucene index in the dataDir.
Here's the Exception I receive when starting Solr and when attempting to
add a document to the core:

Before this point I've been using existing Lucene indexes (created by
the Lucene API) with Solr without a problem.

You don't have to use the Lucene API though?
Solr creates the index if its not there ...
