RequestHandler init failure

[Mingfeng Yang]

When trying to use SolrEntityProcessor to do data import from another solr
index (solor 4.1)

I added  the following in solrconfig.xml

 <requestHandler name="/data"
class="org.apache.solr.handler.dataimport.DataImportHandler">
   <lst name="defaults">
   <str name="config">data-config.xml</str>
   </lst>
   </requestHandler>

and create new file data-config.xml with
<dataConfig>
  <document>
    <entity name="sep" processor="SolrEntityProcessor"
url="http://wolf:1Xnbdoq@myserver:8995/solr/"; query="*:*"
fl="id,md5_text,title,text"/>
  </document>
</dataConfig>


I got the following errors:

I assume that it's because jar file related to dataimporthandler is not
included in default solr 4.1 distribution.  Where can I find it?

Thanks
