It sounds like maybe you either have not told Solr where the Solr home directory is, or , more likely, have not copied the jar files for this particular class into the right directory (typically a "lib" directory) so Tomcat cannot find that class. There is other correspondence on this list that you can look for that discusses the options for defining the Solr home directory.

It all happens when I use tomcat and solr. My setup is as follows: I downloaded the apache-solr-3.3.0 and unpacked it....I am using "apache-solr-3.3.0" folder as my solr-home folder. Inside the "dist" folder I have the apache-solr-3.3.0.war and coppied everything from the contrib/extraction/lib into dist. I would greatly appreciate it if you can possibly point me to the right direction. I have read everything on the wiki page and the documentation but no luck! regards, Sina -- Sina Fakhraee , PhD candidate Department of Computer Science Wayne State University 5057 Woodward Avenue 3rd floor, Suite 3105 Detroit, Michigan 48202 (517)974-8437(Cell) http://uwerg.cs.wayne.edu/ShowPage.aspx?node=0c5b13ef-2d8e-4abd-a216-a2037d947b63&acc=1
