Yes, those were the directories I was taling about. > the only reason to ever copy any jars arround when dealing with solr is to > load plugins (ie: your own, or things counts in the contrib directory of a > solr release) and even then they should go in the special "lib" directory > inside your Solr HOme directory so they are loaded by the appropraite > classlaoder -- not in the top level class loader of your servlet > container. Ok, I'm not sure where my particular use of Solr fits into all this. I'm writing a log4j appender that adds each log entry to a Solr index. It's not really a Solr plugin. > : [SolrResourceLoader] Unable to load cached class-name : > : org.apache.solr.search.FastLRUCache for shortname : > : solr.FastLRUCachejava.lang.ClassNotFoundException: > : org.apache.solr.search.FastLRUCache > > this is most likely because you have duplicate copies of (all of) the solr > classes at various classloader levels -- the copies in the solr.war, and > the copies you've put into the JBoss lib dir. having both can cause > problems like this because of the rules involved with > hierarchical classloaders. I've removed all the extra files from the lib directory as you suggest, and now I get the following message when starting JBoss 18:54:23,083 ERROR [AbstractKernelController] Error installing to Create: name=jboss.system:service=Logging,type=Log4jService state=Configured mode=Manual requiredState=Create java.lang.NoClassDefFoundError: org/apache/solr/client/solrj/SolrServerException
