Enable Clustering for Solr war

[Darren Govoni <da...@ontrenet.com>]

Hi,
  I'm trying to get clustering setup for Solr 1.4 in war mode on tomcat
6.

I read the instructions on the wiki, checked out the trunk and got the
downloaded libraries. There's no instruction on what to do with them so
I copied them to tomcat/lib directory. I set property to enable
clustering in tomcat. When I start tomcat, I get.

You can put them into $solrhome/lib directory. From readme.txt

 "lib/
        This directory is optional.  If it exists, Solr will load any Jars
        found in this directory and use them to resolve any "plugins"
        specified in your solrconfig.xml or schema.xml (ie: Analyzers,
        Request Handlers, etc...). "

I added these jars to lib and using clustering component without problems:

apache-solr-clustering-1.4.0.jar  jackson-mapper-asl-0.9.9-6.jar
carrot2-mini-3.1.0.jar            log4j-1.2.14.jar
colt-1.2.0.jar                    nni-1.0.0.jar
commons-lang-2.4.jar              pcj-1.2.jar
ehcache-1.6.2.jar                 simple-xml-1.7.3.jar
google-collections-1.0-rc2.jar    
jackson-core-asl-0.9.9-6.jar
