The solr home dir is as suggested for solr 4.0 to be located below jetty. So my directory structure is: /srv/www/solr/solr-4.0.0/ -- dist ** has all apache solr and lucene libs not in .war -- lib ** has all other libs not in .war and not in dist, but required -- jetty ** the jetty copied from solr/example with context, etc, webapps, ... jetty/solr ** solr with its subdirectories jetty/solr/conf jetty/solr/data jetty/solr/solr.xml
Currently lucene-core is also in lib directory because of the error message. I thought this would fix my problem, but no change so if I remove it the error remains. In solrconfig.xml I have only two lib directives: <lib dir="../../dist" /> <lib dir="../../lib" /> Strange thing is, solr/example starts without problems and I could also start my solr-4.0.0 development installation from eclipse with runjettyrun. Just tested, after removing lucene-core from lib directory the error remains the same. Seriously a stupid config error, but where?
