Hi,
Should a Rails developer consider using GWT as a core component, or is
the
concept that rails uses prototype so rails developers should focus on
use of
prototype?
Tks

Its actually quite alien really - you design your layouts in Swing and
then
cross-port them to HTML+AJAX. Its obviously a successful model for
google and something that really appeals to a large chunk of the java
community who aren’t in the Web development camp.
It just seems to me (even as a Java developer) about as good a fit for
web developement as learning classic french literature through
japanese.
It would be even less relevant to a Rails developer. The primary purpose
of GWT is to bootstrap you into web 2.0 technologies by leveraging
Java skills.

That may be so, but as a rails developer I feel a little envious of some
of the features in GWT, such as their browser history management:
http://code.google.com/webtoolkit/documentation/com.google.gwt.user.client.History.html
of course it may be that I can easily achieve the same effects with
rails, but just haven’t worked out how.
Another thing is that I’m quite envious of the google homepage, which I
assume is built using GWT, with it’s collapsible windows. I have
implemented collapsible windows in our rails app, but it feels a bit
messy.
I guess I have to come out of the closet 
and admit that I did my
first graphics programming in swing/AWT and the idea of having a widget
into to which I can drop my content into is appealing. Of course it may
just be that I haven’t found quite the right way of creating a single
template that I can use generically across all the collapsible windows
in our current rails app.
Just thinking out loud …

In reality, it’s not as though Rails depends heavily on Javascript at
all. Prototype is not a necessity… it’s reasonably easy to drop GWT
code into Rails (just put the files into /javascripts and link them
like normal). You miss out on Rails helpers and RJS, but you also miss
out on browser quirks and a totally non-widget-oriented framework.
I’d say, if you feel significantly more comfortable with Java than with
JS, or if you really dig the widgetty nature of the GWT, go for it.
