java - solr.extraction.ExtractingRequestHandler ClassNotFoundException -


i working on internal project in company requires solr, not manage link tika. bought apache solr 4 cookbook yet couldn't figure out solution.

  1. i copied required jar files lib directory
  2. i added lib directory in solrconfig.xml

when remove start="lazy" in requesthandler="update/extract" following error: 

org.apache.solr.common.solrexception: requesthandler init failure ... ... caused by: org.apache.solr.common.solrexception: requesthandler init failure ... ... caused by: org.apache.solr.common.solrexception: error loading class 'solr.extraction.extractingrequesthandler' ... ... caused by: java.lang.classnotfoundexception: solr.extraction.extractingrequesthandler

make sure have apache-solr-cell jar , dependencies in extraction lib in solr library , being loaded solr when solr starts.

<lib dir="../../dist/" regex="apache-solr-cell-\d.*\.jar" /> <lib dir="../../contrib/extraction/lib" />
