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
[SolrResourceLoader] Unable to load cached class-name
Bit of a long error message, so I won't post it all in the subject :-) I'm trying to create a log4j solr appender to help us track down log entries from across our jboss cluster, I might be able to make use of the faceted search to identify errors that occur more often and things like that. Anyway, on to my problem, you can see the source on github http://github.com/Stubbs/solrIndexAppender I've deployed the contents of dist/ into JBoss's lib directory for the server I'm running and I've also copied the contents of lib/ into there as well. I've also copied the solrj libs into there too, but I get the following error: [SolrResourceLoader] Unable to load cached class-name : org.apache.solr.search.FastLRUCache for shortname : solr.FastLRUCachejava.lang.ClassNotFoundException: org.apache.solr.search.FastLRUCache I've seen posts that suggest this is because of usuing 1.3 libs, but the only 1.3 libs I have are in my maven repo and are not deployed. -S Follow me on Twitter: http://twitter.com/stubbs Blog: http://stubblog.wordpress.com My art: http://stuartgrimshaw.imagekind.com Stock Images: http://en.fotolia.com/partner/16775

This was my problem also.
Commenting out that element has solved that problem, and introduced another one.
Even though I'm adding 11 documents at a time, when I look at the
instance with the web interface I see this in the statistics:
numDocs : 4
maxDoc : 24
I've run it a couple of times and the first run gave:
numDocs : 2
maxDoc : 12
I don't understand what's happening because I'm not deleting any from
the archive, shutting down the util I'm using to doesn't say anything
about removing any.

Anyway, I'll try and fix it and make another post if I cant work out what it is.
Solrj writes data to local directory
I have a Solr instance in a directory in 1 location on my hard drive, and set solr.solr.home to that location, when I open it, I can add documents and close the instance with no problem, but the data is written to a new directory solr/data in the current directory. Has anyone seen this before? -S Follow me on Twitter: http://twitter.com/stubbs Blog: http://stubblog.wordpress.com My art: http://stuartgrimshaw.imagekind.com Stock Images: http://en.fotolia.com/partner/16775
