title: Java ScriptEngine supported languages
body: <p>Java has a <a href="http://docs.oracle.com/javase/7/docs/api/javax/script/ScriptEngine.html">ScriptEngine</a> system that allows you to run/evaluate statements in a different language.<br>
  I know for a fact that JavaScript is supported, but I couldn't find any other languages to work with it.<br>
  Is, for example, Ruby implemented?</p>
