Solr: sorry, no dataimport handler defined

Question

I am trying to index my data from oracle database in Solr. To do this, I created a core called "orc" in Solr. My database name is a school that has three fields: id, name and pricipal. Below are my files:

schema.xml file :

 <uniqueKey>id</uniqueKey>
  <!-- Fields added for oracle school table load-->
 <field name="name" type="text_general" indexed="true" stored="true"/>
 <field name="principal" type="text_general" indexed="true" stored="true"/>

file data-config.xml :

<dataConfig>
    <dataSource name="jdbc" driver="oracle.jdbc.OracleDriver" url="jdbc:oracle:thin:@localhost:1521/XE" user="system" password="*****"/>
    <document>
        <entity name="school" query="select * from school">
            <field column="id" name="id" />
            <field column="name" name="name" />
            <field column="principal" name="principal" />
        </entity>
    </document>
</dataConfig>

solrconfig.xml file :

   <lib dir="${solr.install.dir:../../../..}/dist/" regex="solr-dataimporthandler-.*\.jar" />
   <lib dir="${solr.install.dir:../../../..}/contrib/extraction/lib" regex=".*\.jar" /> 
   <lib dir="${solr.install.dir:../../../..}/dist/" regex="solr-cell-\d.*\.jar" /> 
   <lib dir="${solr.install.dir:../../../..}/contrib/clustering/lib/" regex=".*\.jar" /> 
   <lib dir="${solr.install.dir:../../../..}/dist/" regex="solr-clustering-\d.*\.jar" /> 
   <lib dir="${solr.install.dir:../../../..}/contrib/langid/lib/" regex=".*\.jar" /> 
   <lib dir="${solr.install.dir:../../../..}/dist/" regex="solr-langid-\d.*\.jar" /> 
   <lib dir="${solr.install.dir:../../../..}/contrib/velocity/lib" regex=".*\.jar" /> 
   <lib dir="${solr.install.dir:../../../..}/dist/" regex="solr-velocity-\d.*\.jar" /> 

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

All three of these files are located in solr-5.3.0 \ server \ solr \ orca \ conf .

It does not give any errors, but also does not define a dataimport handler.

I can’t understand what the error is. Please help!

Do a check of only 3 things:

• jar lib solrconfig.xml

• ,

• .
