Hi, I think the exception is caused by the fact that you're trying to use the latest version of Carrot2 with Solr 1.4.x. There are two alternative solutions here:
* as described in http://wiki.apache.org/solr/ClusteringComponent, invoke "ant get-libraries" to get the compatible JAR files. or * use the latest version of Carrot2 with Solr 1.4.x by installing the compatibility package, documentation is here: http://download.carrot2.org/stable/manual/#section.solr Cheers, Staszek On Tue, Jan 18, 2011 at 13:36, Isha Garg <isha.g...@orkash.com> wrote: > Hi, > Can
