The adminPath (/admin/cores) is a *URL* path, not a *filesystem* path. Let's back up a bit. Your tomcat config needs some way to start Solr. This can either be done by dropping "solr.war" into an automatic deployment directory, or placing an XML file (context fragment) telling Tomcat how to find the .war, the context path (usually /solr) and possibly some other settings. https://wiki.apache.org/solr/SolrTomcat#Installing_Solr_instances_under_Tomcat Part of the config that you can give is a directory known as the Solr Home. If you don't specify it, it defaults to "./solr" -- meaning a directory named "solr" in the current working directory of the process that actually starts your container. I highly recommend that you specify the solr home, either with "-Dsolr.solr.home=/path/to/solr" on the java commandline, or with a JNI environment variable named "solr/home" in the context fragment. Once you have your Solr Home figured out, you put your solr.xml file there, and your instanceDir for each of your cores will be relative to that directory as well. Inside the instanceDir you must have a conf directory, which contains solrconfig.xml and schema.xml, plus any other config files referenced by those two files. If you're running SolrCloud, then the config is in zookeeper, not on the disk in the conf directory, but the instanceDir for each core works much the same other than that. I would recommend you have persistent set to true in your solrconfig.xml file. A great number of possible problems with the CoreAdmin API can be avoided that way. Thanks, Shawn
