I have Solr 1.4 running on Tomcat6 installed in an Ubuntu 10.04 LTS openVZ container. I am looking for documentation on Solr. I need to know where Solr and Tomcat do their logging by default when installed from the standard Ubuntu apt repo. I would like to know more about both technologies but Solr in particular seems to be lacking some good documentation. Can someone point me in the right direction?
