Getting error. org.apache.solr.common.SolrException: Error loading
class 'org.apache.solr.handler.dataimport.DataImportHandler
I am new for solr. I have installed apache tomcat 7.0 on my server and I
have solr 3.6.1 on server.
I have solr-home folder set by network guys on my D:\ drive. The folders in
that are: bin,etc,logs,multicore,webapps.
In the multicore folder there are: core0,core1,exampledocs,README.txt and
solr.xml. In webapps folder I have solr.war file nothing else.
Now I keep one more core folder in multicore folder named
ConfigUserTextUpdate which have conf folder in it and restart the tomcat
service and I can see the new core on the localhost/solr.
Now I add db-config.xml to the ConfigUserTextUpdate core. Below is the
content:
<dataConfig>
<dataSource
type="JdbcDataSource"
driver="com.microsoft.sqlserver.jdbc.SQLServerDriver"
url="jdbc:sqlserver://<dbname>\<servername>;databaseName=dbname"
user="username"
password="password"/>
<document>
<entity name="ConfigUserTextUpdate" query="UserTextUpdate_Index">
</entity>
</document>
</dataConfig>
Upto here everything is fine and all the three cores are shown on
localhost/solr. Now in the solrconfig.xml of the core ConfigUserTextUpdate
I add the line
<requestHandler name="/dataimport"
class="org.apache.solr.handler.dataimport.DataImportHandler">
<lst name="defaults">
<str name="config">db-data-config.xml</str>
</lst>
</requestHandler>
And it starts giving the error as shown below:
HTTP Status 500 - 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: false in
solr.xml -------------------------------------------------------------

I have tried many things as putting the dataimporthandler.jar file in the
core folder and other many things given on various sites but still getting
the same error. Please help me with these.
Let me know if you need some more information.
Thanks in advance.

Hello!
It seems that Tomcat can't see the the jar's with DataImportHandler.
Did you try adding a <lib> tag to your solrconfig.xml, ie.: something
like this:
<lib dir="/usr/share/solr/lib/" regex="apache-solr-dataimporthandler-\d.*\.jar" />
And putting the apache-solr-dataimporthandler-3.6.1.jar and
apache-solr-dataimporthandler-extras-3.6.1.jar to /usr/share/solr/lib
?
