What is it?

This project provides a CDI ("Contexts and Dependency Injection for the Java^TM EE platform", defined by JSR 299) portable extension, which allows to retrieve JSR 223 ("Scripting for the Java^TM Platform") script engines via dependency injection.

Just annotate any injection points of type javax.script.ScriptEngine with one of the qualifier annotations @Language, @Extension or @MimeType. The following shows an example of a JavaScript engine (for example the Rhino engine shipping with Java 6) being injected into some managed bean, where it can be used for arbitrary script evaluations:

@RequestScoped
public class MyBean {

	@Inject 
	@Language("javascript") 
	private ScriptEngine jsEngine;

	// ...

	public void foo() throws ScriptException {

		assert 42.0d == (Double)jsEngine.eval("2 * 21");
		// ...
	}

}
