The Javascript Scripting Library is a Generic mixin class that implements Composite interfaces by delegating to JavaScript functions using Rhino. Each method in an interface is declared as a JS function in a file located in classpath with the name "<interface>.<method>.js", where the interface name includes the package, and has "." replaced with "/".

Example:

org/apache/zest/samples/hello/domain/HelloWorldSpeaker.say.js

That means that the HelloWorldSpeaker.say.js file may be co-located with the class files in the same package. It is currently not supported to place the Javascript implementation of the mixin in a different package than the interface it implements.

To use Javascript to implement the Mixin functionality for a given interface, simply declare the JavaScriptMixin like any other mixin, either in the interface or at assembly time.

@Mixins(JavaScriptMixin.class)
public interface HelloSpeaker
{
    void sayHello();
}
