Thanks, that helped with a different issue I was having. However the Admin UI issue is a known issue with IE9 (and possibly IE8) https://issues.apache.org/jira/browse/SOLR-3876 https://issues.apache.org/jira/browse/SOLR-3841
basically IE is not supported for the Solr Admin UI at this time. I installed Chrome on the Development server I'm working with and everything worked just fine. -- View this message in context: http://lucene.472066.n3.nabble.com/Can-Solr-v1-4-and-v4-0-co-exist-in-Tomcat-tp4021146p4021455.html Sent from the Solr - User mailing list archive at Nabble.com.
