btw, this looks like you are you using current 1.3 or head versions of classes in Schema.xml or solrconfig.xml, but you are running on a 1.2 version of solr. Perhaps if you look up the output a bit you'll see it finding and loading these files. And then blowing out on one of them. You basically need to get the jar files with the support you have. The easiest way I know is get 1.3. I'm still quite novice with solr admin, but this one I've seen before. Hope this helps. gene On Fri, Oct 3, 2008 at 10:14 AM, ristretto. rb <[EMAIL PROTECTED]> wrote: > I had absolutely not luck with the jetty-solr package on Ubuntu 8.04. > I haven't tried Tomcat for solr. > I do have it running on Ubuntu though.
