Subject Stuck on SEVERE: Error filterStart
Date Wed, 16 Apr 2014 15:47:48 GMT
I am trying Solr for the first time, and I am stuck at the error "SEVERE:
Error filterStart"

My setup:
 - Centos 6.x
 - OpenJDK 1.7
 - Tomcat 7

>From reading [1] I believe the issue is missing JAR files, but I have no
idea where to put them, even the wiki is a bit vague on that.

Lib directories that I am aware of
 - /usr/share/tomcat/lib (for tomcat)
 - /opt/solr/example/solr/collection1/lib (for my instance)


This is the error I get:

Apr 15, 2014 11:35:36 PM org.apache.catalina.core.StandardContext
filterStart
SEVERE: Exception starting filter SolrRequestFilter
java.lang.NoClassDefFoundError: Failed to initialize Apache Solr: Could not
find necessary SLF4j logging jars. If using Jetty, the SLF4j logging jars
need to go in the jetty lib/ext directory. For other containers, the
corresponding directory should be used. For more information, see:

I would like to get past this so I can try out Solr.

I have gone as far as putting `<lib
dir="/opt/solr/example/solr/collection1/lib/" regex="*\.jar" />`
into /opt/solr/example/solr/collection1/conf/solrconfig.xml but that did
not help.

I have used Java before, but purely for academic purposes, so I do not have
experience resolving these dependencies.
