Re: j2s-development] about javascript native

[Zhou R. <zho...@gm...>]

boolean b = false;
/**
 * @j2sNative b = true;
 */ {}
if (b) {
    A();
} else {
    B();
}

Auto refactoring will fail when refactoring codes inside @j2s* annotations.
We always recommend Java codes instead of JavaScript, unless it is a
JavaScript-must task.

About Java2Script HTML/CSS toolkit using XHTMLRender, I would like to know
something more. I am not quite sure about compatibility between XHTMLRender
and modern browsers. Could you please tell us more about your experience of
integrating XHTMLRender inside Java application?

I had some project experiment on using Java2Script with native HTML/CSS. No
Java debug environment. Everything was tested inside browsers. But it was
still acceptable as I were using debug mode, which Java2Script's "Hotspot"
classloader is enabled inside.

For your plugin, if there is no copyright problem and you would like to
share it with us, you can send us a copy. There should be some ideas that
Java2Script can learn from.
