Im trying to parse solr variable to include differnet database settings depending on a variable.
-Dsolr.host=dev2.cr9
In solr log I got this exception
Exception during parsing file: solrconfig.xml:org.xml.sax.SAXParseException; systemId: solrres:/solrconfig.xml; lineNumber: 91;
columnNumber: 123; An include with href 'file:///var/lib/solr/conf/database.dih.${solr.host}.xml'failed, and no fallback element was found.
How can I parse solr variable href -> using <xi:include href=""
I have done it in a different way.
The following sample attempts to include database.dih.prod.cr.xml If it doesn't exist or can't be loaded then database.dih.dev.cr.xml will be used instead.
solrconfig.xml
<!--- including database config -->
<xi:include href="file:///var/lib/solr/conf/database.dih.prod.cr.xml" xmlns:xi="http://www.w3.org/2001/XInclude">
<xi:fallback>
<xi:include href="file:///var/lib/solr/conf/database.dih.dev.cr.xml" />
</xi:fallback>
</xi:include>
database.dih.web0.psnt.xml
