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
