Hi,Thanks for your reply. It looks great. However I found out the speed of grid are a bit slow compare to SmartGWT.Can we write client logic in Java and let the compiler translate that to _javascript_ ? some things like GWT.j2s looks good as well. only the UI looks a bit Win9x.ThanksOn Thu, Feb 11, 2010 at 1:34 AM, Rüdiger Herrmann <rherrmann@xxxxxxxxxxxxxxxxx> wrote:

Hi,
Thanks for the reply. sorry about that. Ya, RAP are filling the gape
for this area. Sorry, I forgot about RAP project. This is great....
About RAP, Can I simply use RWT instead of RCP ? Sorry for my stupid
questions...
See here for a more detailed introduction to RAP:
http://eclipse.org/rap/introduction.php
Thanks again! Good to hear that SWT now exist in Web platform as well.
Best is it use back Java language.
Oh ya! can I use Java in RWT client side for logic ?
Thanks and Best Regards,
Ivan

Hi,
as Lars already pointed out, the RAP project already allows you to
single-source your existing code to bring your RCP application to<mailto:yves.yang@xxxxxxxxxxx> <mailto:yves.yang@xxxxxxxxxxx
problems Tom mentioned are real, but only some of them. Eg. the
event-loop is part of RAP for several releases and has proven to
work efficiently in a server-centric environment. Operating system
resources are available too (eg. Fonts, Cursors, etc). The only
missing part is a proper GC implementation which heavily relies on
the capabilities of modern browsers but depending on your task at
hand you could use the RAP theming to customize the look and feel of
the application (eg. roundend corners or gradients).
Hope that helps,
Ben

It is exactly one of benefice of using XWT: physical
separation between
event handling and UI. XWT can manage the both cases
transparently.
We can
define the event handling policy (sync, async and delayed
async) between
declarative UI and event handling based on Java Handling, Bundle
service,
web service etc.
