j2s-development] about javascript native

[Sebastian G. <sg...@mo...>]

Hi all. Well, this is my first post to this forum. I'm starting to play
with java2script and I think it is a very promising piece of software.
(excuse me for my bad english)

SWT port to js is great but (imho) is not oriented to the web (big,
don't take advatage of css styles, ...). So I decided to start
developing a small toolkit, with a simple visual paradigm that supports
css styles, basic events and layouting and use a 100% java, free xhtml
renderer (https://xhtmlrenderer.dev.java.net/ ) so applications can be
tested in java and the translated to js. 

The thing is that i'm using @j2s* java annotations for expressing native
javascript code. My problem is that from a javascript native code I want
to call a java method, and this will create problems when auto
refactoring the code with eclipse. So my question is if there is a java
annotation for execute a code block A in javascript environment and B in
a java environment. Something that translate the following code

P1
if(false) 
/** @j2sSOMETHING */
{
	A
}
else {
	B
}
P2

to the next javascript code:

P1
A
P2

(in java the block A will be never executed). 

Well, if there isn't something like that, it would be nice because it is
nice to test web applications first in a jvm, but to use the ide
refactoring tools too!!)

I hope you can understand my point. Congratulations again for this
project and for make it opensource. 

p/d
I had investigating about making a java to javascript translator using
eclipse ' jdt, but, although jdt's ast parser is makes very easy to
analize a java compile unit, it is hard to create the equivalent
javascript code. So, when I saw java2script and check that the
translator works well, i surrender... and now i move on using java2js.
If you want, only for curiosity, i could send my eclipse plugin with
this unfinnished translator (i use java annotations for javascript
native code too!!)
