Scaling and replication

Monday 30 March 2009 11:40:05 pm

Hi all !

We are trying to configure a master/slave replication for Solr/eZFind 2. We followed this doc : http://www.lucidimagination.com/Community/Hear-from-the-Experts/Articles/Scaling-Lucene-and-Solr#d0e323

But when the conf is on, we got the following error. It seems that the class <i>solr.ReplicationHandler</i> is missing.
Does anyone have an idea where I can find this class ?
