Hoss Man commented on SOLR-337:
-------------------------------

Note: a specific error about not finding a "./conf" dir in the solr home dir would be handy too.

> If a user types in a bad location for solr/home in  JNDI or doesn't have one set, it causes a stack trace that has no obvious relationship with the cause (No Class Defined).  It would be nice if the user got an error message instead about what the problem is.  Given the number of non-Java users, this could be especially confusing to them.
