Have you guys checked the http://github.com/chirino/resty-gwt project?
It has a generator
that does pretty much all the "awful" things Roger talks about.

Hi Roger,
Then the only option left is xml, of course if we are not going
GWT-RPC way.
So what do you think will be better JSON or XML ?
I have created a GWT application, the communication with server part
is pending, the server side is java but its an already existing
application, so I need to hook something in between the service side
application & GWT to communicate, so I am looking out if it should be
json or xml.

And to add one thing.
Using JSON w/ GWT is well.. "awful".
The main reason for this, is that you get JSON back to the client,
and either use Overlay Types (can't use instanceof with there, and
about 500 other issues).. or you hve to take a "simple"
OverlayType and then re-instantiate all of your objects (i.e. you
do eval() once on the JSON, then for-loop etc to re-instantiate
objects from that JSONObject).
And then, the joy doesn't stop. When you want to say, post JSON
back to the server, you have to redo this process, converting all
the "java objects" (which are of course actually javascript) into
JSON.
All in all, using JSON w/ GWT is a very (very) painful experience.
THe humor of course, is that you have to convert objects "to and
from Java" so that you can then use all the "java" API's etc that
GWT (just converts into Javascript).
Heh

The problem is the GWT RPC's serialization, which can't work with
objects created by hibernate. You can use the DTO Grails plugin
(http://www.grails.org/plugin/dto) or you can use JSON / REST for
communication.
In the case of a Grails app, which comes with great support for
REST / JSON, I would prefer the second way.

GWT is the obvious choice for UI. But if you want to use
Grails/Groovy
for server side, you have to either code messy DTOs or client
side
POJOs. It would be nice if GWT would support using the
Grails/Groovy
domain objects directly on the client. Any chance of that
happening?
