I am trying to import data from SQL server using DIH.I am getting below exception.

Please help me to resolve this and tell me is there any other way to index data into solr without using DataImportHandler or Is there any way to index data to solr using any C# app or something like that ?

Thanks in advance.

Answer 1

Add apache-solr-dataimporthandler-x.y.z.jar and apache-solr-dataimporthandler-extras-x.y.z.jar files into the lib folder in Solr home and configure lib directory in solrconfig.xml file.

Another way to index data is to use SolrSharp project.
