java.lang.NoClassDefFoundError: org/carrot2/core/ControllerFactory
<p>
Hi,
I am new to solr and successfully did a basic search. Now i am trying to do
classification of the search results using carrrot's support which comes
with solr 4.5.1. Would appreciate if someone tells me what is that i am
missing...may be a trivial issue??!!!
I am getting the below error..*java.lang.NoClassDefFoundError:
org/carrot2/core/ControllerFactory*. I know this error might be because of
carrot2 classes not getting loaded. But if you look below the jars in the
"../contrib/clustering/lib" directory are being loaded. but still i am
getting the error. what might be the reason?
I am working with Solr 4.5.1 on tomcat 7.0.47.

Have you defined the sharedLib setting in your solr.xml file to point at
these jars? If you have, you'll need to remove that.
I've summarized the issues with jar loading and sharedLib on the
12/Nov/2013 comment for this issue:
https://issues.apache.org/jira/browse/SOLR-4852
My recommendation for anyone that needs extra jars with Solr: Remove
all <lib> directives from solrconfig.xml. Copy all jars that you
actually require to ${solr.solr.home}/lib. Because you're on 4.5.1,
remove the sharedLib setting from solr.xml. If you were on 4.2.1 or
earlier, you'd need the sharedLib setting, with lib as the value.
Thanks,
Shawn
