Solr, mail # user - access to environment variables in solrconfig.xml and/or schema.xml?

access to environment variables in solrconfig.xml and/or schema.xml?

Burton-West, Tom 2010-12-13, 19:28

I see variables used to access java system properties in solrconfig.xml and schema.xml:

http://wiki.apache.org/solr/SolrConfigXml#System_property_substitution
<dataDir>${solr.data.dir:}</dataDir>
or
${solr.abortOnConfigurationError:true}

Is there a way to access environment variables or does everything have to be stuffed into a java system property?

Tom,

No, there is no way to access environment variables. But you can
access your environment variable through a java system property
if you assign the environment variable to a java system property
when you launch JVM:

$ java -Djava.system.property1=$ENVIRONMENT_VAR1 ï¿½
-Djava.system.property2=$ENVIRONMENT_VAR2 -jar start.jar
