You will need to create a context XML file for each Solr instance to tell it where to find its indexes (aka solr_home). Obviously, each Solr instance will want a different one.
See: http://wiki.apache.org/solr/SolrTomcat#Installing_Solr_instances_under_Tomcat Note that it says to create a file in $CATALINA_HOME/conf/Catalina/localhost/solr-example.xml, you should replace 'solr-example' with whatever you name your webapps.
