Hmmm, I may have made progress by passing the arguments at the "docker run" stage:
But when the curl command is issued per to add the request handler, I receive this reply: timc@Debian$ curl -X POST -H 'Content-type:application/json' -d '{ "add-requesthandler": { "name": "/update/extract", "class": "solr.extraction.ExtractingRequestHandler", "defaults":{ "lowernames": "true", "captureAttr":"true"} } }' 'http://localhost:8983/solr/gettingstarted/config' { "responseHeader":{ "status":400, "QTime":24}, "errorMessages":["error processing commands, errors: [{add-requesthandler={name=/update/extract, class=solr.extraction.ExtractingRequestHandler, defaults={lowernames=true, captureAttr=true}}, errorMessages=[ Error loading class 'solr.extraction.ExtractingRequestHandler']}], \n"], "WARNING":"This response format is experimental. It is likely to change in the future.", "error":{ "metadata":[ "error-class","org.apache.solr.api.ApiBag$ExceptionWithErrObject", "root-error-class","org.apache.solr.api.ApiBag$ExceptionWithErrObject"], "details":[{ "add-requesthandler":{ "name":"/update/extract", "class":"solr.extraction.ExtractingRequestHandler", "defaults":{ "lowernames":"true", "captureAttr":"true"}}, "errorMessages":[" Error loading class 'solr.extraction.ExtractingRequestHandler'"]}], "msg":"error processing commands, errors: [{add-requesthandler={name=/update/extract, class=solr.extraction.ExtractingRequestHandler, defaults={lowernames=true, captureAttr=true}}, errorMessages=[ Error loading class 'solr.extraction.ExtractingRequestHandler']}], ", "code":400}} Any ideas, anyone?
