Solr home wrong or missing generates class not found exception
--------------------------------------------------------------
Key: SOLR-337
URL: https://issues.apache.org/jira/browse/SOLR-337
Project: Solr
Issue Type: Improvement
Environment: Tomcat 5.5.23
Reporter: Paul Sundling
Priority: Minor
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.
