The BlockJoinFacetComponent class was introduced in Solr 5.5. https://issues.apache.org/jira/browse/SOLR-5743 The error you are seeing is because of this text in the solrconfig.xml provided with casebox: <searchComponent name="blockJoinFacet" class="org.apache.solr.search.join.BlockJoinFacetComponent"> </searchComponent> Removing that XML and any other XML where that component is referenced would fix the error, but I would imagine that that casebox would not work correctly after the change. I do not know if you can copy the class from a newer version into the 4.10 source code. From what I've seen, Solr code changes so fast from release to release that you would probably run into big problems trying to adapt a plugin that's intended for 5.5 and newer to a 4.x version. Even if you copy the code for the missing class, that code probably depends on other changes and additions that have happened in the many releases between 4.10.4 and 5.5. Your best bet is to talk to the casebox people. They can tell you exactly what is required for their software, and whether or not they are willing to support such an old version of Solr. If I had to guess, they probably *can't* support older Solr in their newest versions. Their software probably relies on capability (like BlockJoinFacetComponent) only available in newer Solr versions. If you were to use a version of casebox before March 15th, it *might* work. This commit was made on that date, and among other changes, added BlockJoinFacetComponent to solrconfig.xml: https://github.com/KETSE/casebox/commit/3fdc48564efd35e8a0229cb86bdab0ad4f493511 Thanks, Shawn
