Subject RE: SpellCheckComponent problems (was: Multiple search components in one handler - ie spellchecker)
Date Mon, 28 Jul 2008 16:24:58 GMT
Well I will include the stack trace for the aforementioned error:

Jul 28, 2008 12:20:17 PM org.apache.solr.common.SolrException log
SEVERE: org.apache.solr.common.SolrException: Error loading class 'org.apache.solr.handler.component.SpellCheckComponent'

        ... 7 more

The line 95 of MarcImporter.java (the solr import program I am using) is the instantiation
of SolrCore.  So maybe somehow the spellCheckComponent is not getting loaded?

This is the error output I get thrown by instantiating SolrCore:
org.apache.solr.common.SolrException: Unknown Search Component: spellcheck
