How to communicate between javascript and java applet

js-to-java.js

var myApplet = funcToGetApplet();

myApplet.setCallback({

    myMethod: function (args) {
        // do something with args here
    },

    anotherMethod: function (args) {
        // do something with args here
    }

});

// in the applet:

public void setCallback (JSObject cbObj) {

    this.cbObj = cbObj;

}

public void callMyMethod (arg1, arg2, arg3) {

    Object[] args = { arg1, arg2, arg3 };
    this.cbObj.call("myMethod", args);

}
