Hi, I've read from http://wiki.apache.org/solr/SolrLogging that Solr no longer ships with Logging jars bundled into the WAR file.
For simplicity in package management, other than Solr, I'm trying to stay with stock packages from Ubuntu 12.04 (e.g. Tomcat7 etc.) Now I'm trying to find out what do I need to install to meet the Solr Logging requirements, using Ubuntu packages if possible at all. Initially I thought having 'libslf4j-java' would be enough but that still gave me that Tomcat 7 error at startup: May 06, 2013 1:28:00 PM org.apache.catalina.core.StandardContext filterStart SEVERE: Exception starting filter SolrRequestFilter org.apache.solr.common.SolrException: 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.

Any help would be appreciated related to Tomcat configuration etc. Cheers, /jonatan
