Does this work? When trying to display with a URL such as "solr/sandbox/admin/file/?file=/mnt/solr/schema.xml" from the Solr admin console, the following error occurs:
type Status report message Can not find: schema.xml [/mnt/solr/sandbox/conf/mnt/solr/schema.xml] description The request sent by the client was syntactically incorrect (Can not find: schema.xml [/mnt/solr/sandbox/conf/mnt/solr/schema.xml]).
