Jav8

An implementation of the Java Scripting API (JSR223) base on the Google V8 Javascript engine.

Java Specification Request (JSR) 223 helps developers integrate Java technology and scripting languages by defining a standard framework and application programming interface (API) to do the following:

• Access and control Java technology-based objects from a scripting environment
• Create web content with scripting languages
• Embed scripting environments within Java technology-based applications

For more detail, please read the article Scripting for the Java Platform

To use the Jav8 Scripting Engine, place the file jav8-jsr223-xxx.jar to your classpath. Then you could get an instance of the engine this way:

ScriptEngineManager factory = new ScriptEngineManager();
ScriptEngine engine = factory.getEngineByName("jav8");

And you execute the script with the ScriptEngine?.eval method

  try {
    engine.eval("print('Hello, world!')");
  } catch (ScriptException ex) {
      ex.printStackTrace();
  }    

Please check the unit tests for more detail
