Unable to load MailEntityProcessor or org.apache.solr.handler.dataimport.MailEntityProcessor

[Andrew McCombe]

Hi

I am experimenting with Solr to index my gmail and am experiencing an error:

'Unable to load MailEntityProcessor or
org.apache.solr.handler.dataimport.MailEntityProcessor'

I downloaded a fresh 1.4 tgz, extracted it and added the following to
example/solr/config/solrconfig.xml:


<requestHandler name="/dataimport"
class="org.apache.solr.handler.dataimport.DataImportHandler">
    <lst name="defaults">
      <str 
name="config">/home/andrew/bin/apache-solr-1.5-dev/example/solr/conf/email-data-config.xml</str>
    </lst>
  </requestHandler>

email-data-config.xml containd the following:

<dataConfig>
<document name="mailindex">
   <entity processor="MailEntityProcessor"
           user="eupe...@gmail.com"
           password="xxxxxxxxxxxxxxxxxx"
           host="imap.gmail.com"
           protocol="imaps"
           folders = "inbox"/>
</document>
</dataConfig>

Whenever I try to import data using /dataimport?command=full-import I
am seeing the error below:

Am I missing a step somewhere? I have tried this with the standard
apache 1.4, a nightly of 1.5 and also the LucidWorks release and get
the same issue with each.  The wiki isn't very detailed either. My
backbground isn't in Java so a lot of this is new to me.
