i've been look around for anything that was happening with these 2
great components. sadly the g4jsf is a dead end :(.
i've got a JSF website that is now hitting the boundaries of what is
possible in a static html refresh browser and needs GWT badly.
does anyone have any good examples of integrating GWT components to
pull information from the page its placed on and rpc the rest of the
content it needs?
i can place a GWT compenent on the page with div's which is good, but
i'm having trouble getting information from the page (eg ID that link
to a database). what is the command to do that?

Hi will,
I work on a project where we use GWT, seam and facelet. The server is a glassfish one.
Seam is a great framework, and I really see it as a great enhancement to JSF.
It provides many components, including "Seam Remoting".
Seam Remoting allows a remote access to seam components,using Ajax.
And you can replace GWT Services by Remoting calls...
This allows you to easily share data between JSF/Facelet pages and GWT modules via
Seam contexts.
see : http://docs.jboss.com/seam/2.1.1.CR2/reference/en-US/html_single/#gwt
Of course, this may mean deep modifications in your project.
If you wan to integrate a simple GWT module in a page and read hidden input values
from the page I see 2 solutions :
JSNI : Allows you to call JScript in the page.
GWT DOM object : Allows you to manipulate DOM objects.
I'll find a sample and post it there :-)

The jboss doc link gives heaps of food for thought.
Just wondering, am i correct to say that G4JSF became ajax4jsf which
then became richfaces ?
This kinda makes it quite confusing when i have jsf and gwt and no
idea what i can use to glue it together :P
An example would be very helpful :) on the seam application, and maybe
on the other ways of pulling information. :)
I have used spring in the past, tho not starting out and it already
had a very structured hierarchy and as i'm a fresh out of uni, and
this is mostly a green feilds type project, there is way to many
technologies to look at and yet not enough time in the day. :/
The jsf website that i'm now working on had a pre existing database
backend in oracle. The developer before me used netbeans out of the
box features to generate a brand new interface to the oracle database.
(can't remember the backend infrastructure, will find out in the
morning when i'm at work)
The simple stuff is done and now its to the hard stuff.
i have thought of doing through GWT DOM objects, but i would like a
cleaner way of keeping state, the application will be doing big edits
to the database backend if they apply the changes they make and i
would like to allow any not pre-commited changes to either linger till
out of session of save for next session which means that GWT DOM
object pulling for the id/keys won't do.
Google group discussions seems to be quite nice, tho i do miss the
spell check feature that is in gmail. :)

I'm quite overloaded this week, so I won't have too much time to make a detailed answer :-(
From my understanding G4JSF is dead and replaced by ajax4jsf, which is quite different.
It makes no use of GWT.
If you want a clean and powerful way of keeping state in a GWT/Jsf mixed appication ,
seam is really a nice answer.
I do agree that it's not easy to see the light in all these frameworks...
but here is the solution I use.... I' don't know if it's the best, but well it works for me.
We use EJB3 & Glassfish.

You can really use seam as a "glue" between facelets pages and GWT modules.
Basicaly, seam provides "components" (beans in fact) , which can be used from GWT modules and from JSF pages.
From a facelet view, it's really easy to get values and call methods with EL.
From GWT, seam remoting enables the use of seam components instead of OOTB GWT services.
I hope to get some tme to make a little example. It's not easy to extract a sample from my current project...

thankyou for the reply.
what i'm working on is made from woodstock widgets from netbeans with jsf, we have ejb3 persistent objects so we could go via the ejb3 route, we just need some items to talk to the the database entities to change them, the jsf/woodstock components are written with alot of boolean switches to turn on and off parts of the really large pages. i'm talking about 3-4 large tables of information.
there is a menu system made with woodstock plugins. tho due to the complexity of the pages, they are quite hard to get in the correct position in all browsers.
i wonder how difficult getting seam into the mix or ejb3 is going to be?

It's easy to mix both.
you just need an interceptor... and a few tricks :-)
Take a look at this excellent post : http://weblogs.java.net/blog/caroljmcdonald/archive/2008/01/sample_applicat_4.html
( and http://weblogs.java.net/blog/caroljmcdonald/archive/2007/07/sample_applicat_1.html
the first link is an update to the latest versions of Seam & glassfish )
Once you've discovered the power of seam, you can't live without it :-)

hows your work/life load atm?
an example on jsf/gwt with seam in the background would be nice.
I'm still getting my head around what the last developer left (only
doing this project with under 1/2 day a week), it looks like its in a
MVC pattern, but its merged in some parts, which makes it difficult to
see where the the JSF parts should be, the clean model and the
controller which should pass between the 2.
I've found entity managers in the controllers and Javefaces as well.
so hmm. before i can start plugging seam/gwt into this project, i need
a good grasp of what i can plug my gwt into without the jsf items.

hi olivier,willi
nice discussion .. I'm also exploring seam and gwt .. I do have enough
exp
in both the areas , but integration is little bit tricky it seems, In
seam examples
remoting/gwt a simple example to demonstrate seam + jsf .
Im my point of view ..
1) Seam components can be well integrated to gwt remote services.
2)JSF/GWT - gwt is going load any component in division specified
3)On top of it we can use JSNI
How about your ATM application .. are you able to complete it
thanks
