Das Dokument bietet eine Einführung in JRuby, einen Ruby-Interpreter, der vollständig auf der JVM läuft und Java-Threads verwendet. Es beschreibt, wie man Java in JRuby integriert, einschließlich der Einbindung von JAR-Dateien und der Verwendung von Java-Klassennamen. Außerdem wird der Deployment-Prozess einer Ruby-Anwendung über Warbler in einen Servlet-Container erläutert.
