HI, I assume you are trying to add a custom extension, not preparing a general purpose contribution for solr itself ...
We succeeded in loading a custom reduce operation by adding the jar with our code: <lib dir="dir-with-the-custom-code" regex=".*\.jar" /> And then defining an "expressible": <expressible name="thenewname" class="the.custom.class" /> Both changes were made in solrconfig_extra.xml, a file included from our solrconfig.xml.
