Subject Re: Unable to load MailEntityProcessor or org.apache.solr.handler.dataimport.MailEntityProcessor
Date Mon, 05 Apr 2010 22:04:40 GMT
The MailEntityProcessor is an "extra" and does not come normally with
the DataImportHandler. The wiki page should mention this.

In the Solr distribution it should be in the dist/ directory as
dist/apache-solr-dataimporthandler-extras-1.4.jar. The class it wants
is in this jar . (Do 'unzip -l jar' to find the classes inside a jar.)

You have to make a lib/ directory in the Solr core you are using, and
copy this jar into there.
