Subject Re: Sorl 4.0: ClassNotFoundException DataImportHandler
Date Thu, 18 Oct 2012 01:07:54 GMT

: <lib dir="../../dist/" regex="apache-solr-dataimporthandler-\d.*\.jar" />
: 
: And I have all the dist jar files in dist folder. I restarted the tomcat,
: why I am still getting this error:
: 
: java.lang.ClassNotFoundException:
: org.apache.solr.handler.dataimport.DataImportHandler

is the path "../../dist/" correct relative to the instanceDir for your 
solr core?

you should see log messages when the SolrCore is loaded listing every 
plugin jar being added, what do those look like?

For example, when running the DIH example from 4.0...

hossman@frisbee:~/lucene/branch_4_0/solr/example$ java -Dsolr.solr.home=example-DIH/solr/
-jar start.jar 
...
