Could not instantiate listener org.apache.solr.handler.dataimport.scheduler.ApplicationListener

Question

I'm trying to setup dataimportscheduler for my index, when I add:

  <listener>
    <listener-class>
      org.apache.solr.handler.dataimport.scheduler.ApplicationListener
    </listener-class>
  </listener>

to my webdefault.xml and run start.jar, I get:

I added:

<lib dir="../../dist/" regex="apache-solr-dataimportscheduler-1.0.jar" />

to solrconfig.xml (have successfully loaded some other libraries this way), but it doesn't change anything, based on times shown in error message and log files it seems that webdefault.xml is loaded before solrconfig.xml.

I loaded apache-solr-dataimportscheduler-1.0.jar with -cp option of java in command-line, but didn't work.

Any idea what should I do?

I answered a similar question a few days ago. Please check it out. Solr DataImportHandler configuration

If that does not help, the other option is to copy this jar to solr.war's web-inf\lib folder. This can be done in the jetty's exploded folder under webapps...
