Re: JsInterop hello world

That didn't seem to make much of a difference, the generated javascript still have the wrong identifiers, and the error message is the same :(

I wonder if there is something wrong with my build, it looks to me as if the annotations are ignored.
I know that I run gwt 2.8, as I did a lambda to verify that, and I can see that the code server is started with '-XjsInteropMode, JS'.

Could I simplify it further, by removing the namespace or something?

Thanks ...

So I am doing my first baby-steps in JsInterop, exposing a Java class to javascript, and I can't seem to figure out what I am doing wrong.

My java class looks like this:
public class JsHello  {
public String sayHello(String name) {
return "Hello " + name;

And the javascript in my host page like this:
var obj = new poc.Hello();

My browser complains about 'poc' being undefined:
Uncaught ReferenceError: poc is not defined

Which is understandable, when looking at the implementation generated:
_.sayHello_0_g$ = function Cyb_g$(name_0_g$){
return 'Hello ' + name_0_g$;
var Ldk_bitwerk_client_JsHello_2_classLit_0_g$ = cDb_g$('dk.bitwerk.client', 'JsHello', 428, Ljava_lang_Object_2_classLit_0_g$);

I have tried all sorts of things, such using the real package/class name inside @JsExport, omiting the package/class name inside @JsExport and adding @JsType to the class declaration.
I have also tried annotating a constructor instead of the class.

I am running gwt-2.8.0-snapshot with jsInteropMode=JS, and I have committed the code here: https://github.com/bitwerk/jspoc

Any help will be much appreciated ...
