We are trying to upgrade from Solr 3.6.2 to Solr 4.2.1 and are having
problems with using properties in solrcore.properties inside
data-config.xml.
With Solr 3.6.2, we were able to directly use properties in
solrcore.properties inside data-config.xml like ${jdbc.driver},
${jdbc.username}, etc., but these no longer work. We get an exception like
this:

---------------------
If I hard-code the property values in data-config.xml, then the import
works fine.
I even tried configuring them in solr-config.xml like
<requestHandler name="/dataimport"
class="org.apache.solr.handler.dataimport.DataImportHandler">
<lst name="defaults">
<str name="config">data-config.xml</str>
<str name="jdbcDriver">${jdbc.driver}</str>
<str name="jdbcHost">${jdbc.host}</str>
<str name="jdbcPort">${jdbc.port}</str>
<str name="jdbcUsername">${jdbc.username}</str>
<str name="jdbcPassword">${jdbc.password}</str>
</lst>
</requestHandler>
and use them in data-config.xml like ${dataimport.jdbcDriver} and ${
dataimport.request.jdbcDriver}, but these don't work either.
So how does one pass properties to data-config.xml in Solr 4.2.1?
Any help will be appreciated.
Thanks.
