in solrconfig.xml have configured this:

<updaterequestprocessorchain>      <processor class="com.example.solr.update.processor.selftaggerupdateprocessorfactory" lib="custom-libs" version="1">         <arr name="source">             <str>title</str>             <str>desc</str>             <str>subject</str>             <str>content</str>         </arr>         <str name="dest">category</str>      </processor>      ... </updaterequestprocessorchain>

i have tried add custom jar in 2 ways:

  1. add server/lib/ folder jetty jars located. fails error instantiating updaterequestprocessorfactory
  2. add .system collection suggested , make available <processor /> using lib , version attributes, fails caused by: java.lang.classnotfoundexception: com.example.solr.update.processor.selftaggerupdateprocessorfactory

does error instantiating updaterequestprocessorfactory exception tell don't see? move standalone solrcloud require custom code missed?

i think issue moving standalone solr cloud one. specifically, store jar file custom component. not visible nodes , therefore fails.

however, solr 5.2 have new functionality related may want use. allows use config api add library, assuming enable functionality.
