JRuby is deprecated as a scripting language for mashups. You can, however, deploy JRuby scripts for mashups from previous versions.

The external configuration folder, if any, for the Presto Server. See Setting Up an External Presto Configuration Folder for more information.

Important:

web-apps-home/presto/WEB-INF/classes for uncompressed scripts. This is the default location, but is not recommended as it complicates Presto Server deployments. for uncompressed scripts.

Then, restart the Presto Server.
