Using properties from core configuration in data-config.xml

[gistolero]

Hello,

is it possible to use properties from core configuration in data-config.xml?
I want to define the "baseDir" for DataImportHandler.


I tried the following configuration:


*** solr.xml ***

<solr persistent="false">
  <cores adminPath='null'>
    <core name="core0" instanceDir="/opt/solr/cores/core0">
     <property name="solrDataDir" value="/opt/solr/cores/core0/data" />
      <property name="xmlDataDir" value="/home/xml/core0" />
    </core>
    ...
  </cores>
</solr>




*** data-config.xml ***

<dataConfig>
 <dataSource type="FileDataSource" />
  <document>
   <entity name="xmlFile"
     processor="FileListEntityProcessor"
     baseDir="${xmlDataDir}"
     fileName="id-.*\.xml"
     rootEntity="false"
     dataSource="null">
     <entity name="data"
      pk="id"
      url="${xmlFile.fileAbsolutePath}"
      processor="XPathEntityProcessor"
...
</dataConfig>



But this is the result:

...

I tried also to configure all dataimport settings in solrconfig.xml, but I 
don't know how to do this exactly. Among other things, I tried this format:


*** solrconfig.xml ***

...
<requestHandler name="/dataimport" 
class="org.apache.solr.handler.dataimport.DataImportHandler">
 <lst name="defaults">
  <lst name="datasource">
   <str name="type">FileDataSource</str>
   <lst name="document">
    <lst name="entity">
     <str name="name">xmlFile</str>
     <str name="processor">FileListEntityProcessor</str>
     <str name="baseDir">${xmlDataDir}</str>
     <str name="fileName">id-.*\.xml</str>
     <str name="rootEntity">false</str>
     <str name="dataSource">null"</str>
     <lst name="entity">
       <str name="name">data</str>
       <str name="pk">id</str>
       <str name="url">${xmlFile.fileAbsolutePath}</str>
     ...
</requestHandler>
...



But all my tests (with different "dataimport" formats in solrconfig.xml) failed:


...
