Great presentation. The way you put things in order really made my work easier.
I have struggling hard for days to understand this whole JSNI thing.

Kudos…..God Bless You

Great, now I can finally make GWT handle the post-auth methods. Sweet. I love it!

Can I retrive variable like this: var arr = [{"id":1,"name":"mac"},{"id":2,"name":"mac2"}]; into GWT? What type must be retrieved by function?

A good article but it should be stressed using jsni is supposed to only be used VERY sparingly. Use RPC calls whereever possible.

Also try not to use static class/method modifiers – use the lazy form.

Reason being:

The GWT compiler optimises best when left alone to prune and work out where static (i.e non polymorphic/reflection using code) so it can optimise fully – JSNI routines are static and outside the scope of the compiler aswell…

Simple and clear article that solved a problem that I was having for days now.

I was trying to get the event from the YouTube player into GWT to discover when the video had ended, and couldn’t find such a simple solution.

Thanks.

Great article!

A couple of points:
1. You must pass a reference to the current class you can NOT do the following:
this.@com.company.client.BlueApp::runApp()();

2. If you want parameters in your function, add them in the “function()” declaration:

$wnd.showBlueApp = function (someInt) {
x.@com.company.client.BlueApp::runApp(I)(someInt);
};
