Hi,

When I have add the Json request handler as below for update in solrconfig.xml
<requestHandler name="/update/json" class="solr.JsonUpdateRequestHandler"/>

I am getting following error. Version : apache-solr-1.4.1.  Could you please help...

Error is shown below,


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 solrconfig.xml
