Subject Solr DataImportHandler not found
Date Thu, 04 Aug 2011 08:47:13 GMT
I am using Solr 3.3.0 with Tomcat 6.0.26. I was able to successfully install
Solr and i was even able to access its web interface using
http:/localhost:8084/solr/admin.

Now i want to use its dataimporthandler to index data from my database.I
have added following to my solrconfig:

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

I have also created a data-config.xml in same directory.

My solrconfig file has following location for dataimport

  <lib dir="../../dist/" regex="apache-solr-dataimporthandler-\d.*\.jar" /> 
And i have checked that apache-solr-dataimporthandler-3.3.0.jar file exist
in the dist folder at following path
C:\web\solr\example\lib\apache-solr-3.3.0\dist

But whenever I type http:/localhost:8084/solr/dataimport or
http:/localhost:8084/solr/admin/dataimport it says resource unavailable. I
thought it was due to some problem with Tomcat setting so i stopped tomcat
and tried to start Solr from cmd using java -jar start.jar. And i get the
following error

HTTP ERROR 500
Problem accessing /solr/. Reason:
Severe errors in solr configuration.
Check your log files for more detailed information on what may be wrong.
If you want solr to continue after configuration errors, change: 

<abortOnConfigurationError>false</abortOnConfigurationError>

in solr.xml
