rhino

Can someone provide me an example on how to extend a java class in java script using Rhino's java adapter ? For anyone else who might come across this, there's a decent example here (the author uses it to extend awt.Canvas ). var smileyCanvas = new JavaAdapter(awt.Canvas, { paint: function (g) { var size = this.getSize(); var d = Math.min(size.width, size.height); var ed = d / 20; var x = (size.width - d) / 2; var y = (size.height - d) / 2; // draw head (color already set to foreground) g.fillOval(x, y, d, d); g.setColor(awt.Color.black); g.drawOval(x, y, d, d); // draw eyes g.fillOval(x+d/3-

I have some properties in an object that I would like to add to the global namespace. In javascript on the browser I could just add it to the window object like so: var myObject = { foo : function() { alert("hi"); } // and many more properties }; for (property in myObject) { window[property] = myObject[property]; } // now I can just call foo() foo(); But since rhino doesn't have the global window object I can't do that.

But the Node.js uses Google's V8 as the default Javascript engine (JSE) and V8 runs exlusively on the x86 and ARM Instruction Set Architectures (ISA). Now I have a PPC processor Mac computer on which I want to run the Node.js . To do that, I'm adviced to use the Rhino + OpenJDK Shark Virtual Machine + Low Level Virtual Machine ( LLVM ) as the JIT compiler. Currently, that looks like the most applicable way of running Node.js on the PPC ISA. Or, is there a better way to do it? Could you tell beforehand if it would be
