I just tried putting the solr-dataimporthandler-6.6.0.jar in server/solr/lib and I got past the problem. I still don't understand why not found in /dist

I have a custom entity processor that subclasses EntityProcessorBase. When I execute the /dataimport call I get java.lang.NoClassDefFoundError: org/apache/solr/handler/dataimport/EntityProcessorBase no matter how I state in solrconfig.xml to locate the solr-dataimporthandler jar. I have tried: from the existing libs in solrconfig.xml <lib dir="${solr.install.dir:../../../..}/dist/" regex="solr-dataimporthandler-\d.*\.jar" /> from the Ref Guide <lib dir="../../../dist/" regex="solr-dataimporthandler-\d.*\.jar" /> try anything <lib path="C:\Servers\solr-6.6.0\dist\solr-dataimporthandler-6.6.0.jar" /> But, I always get the class not found error. The DataImportHandler class is found when Solr starts, since EntityProcessorBase is in the same jar why is it not found. I have not tried putting in the core's lib thinking the above should work. Of course, the 3rd choice is only an experiment. Thanks. -S
