hi Callum. you can create a directory for your jar file any where,and u must set jar file location in <lib> tag in solrConfig.xml and be carefull that add your lib location at the end of the solr config default <lib> tag, because some times your jar need class that at first solr must be load own class after that load your jar to don't face a class not found exception.
