Spring + Hibernate + GWT is a sound choice and should support most all
of what you need to do. I would look at JBoss SEAM, but then I like
JBoss. All three are tried and tested in the field, so that should
tell you scalability is not an issue. With GWT clients, the key thing
is being able to move
Thank you gregor, I think your advices could be very useful to me.
My biggest concern, anyway, is not to run on multiple clients. Even if
I can't discard this possibility by now, it has not yet been
identified as a requirements of the application.
The biggest concern is to expose a set of

I read a lot of stuff about SOA, MVC, message-based MVC, SOUI ecc...

Hi!
I completely agree with your comparison between GWT-RPC and SOAP XML,
but it is just too convenient for me to reply to your post with the
non-conflicting argument for JSON web services as a viable middle
ground:

Hi Gabor,
Personally, I never use the term web services anymore. It can mean
anything to anybody. I prefer to be specific, so I speak of SOAP,
REST, JSON, XmlHttprequest, GWT RPC etc. as appropriate.
I'm a GWT RPC person myself, but if I needed to expose services to

Some questions:
1)Using GWT RPC, can the servlets be distributed? e.g., the various
servlets that perform business logic can be distributed like web
services can?

with your point of view.
Cause I'm a newby in SOA solutions, I'm reading and reading things and

1) ESB's are good at, and designed for, orchestrating business

not talk to each other easily, whilst providing clients with a single

Interesting..that's what I was also talking about.
The possibility to invoke web services directly from a GWT interface
to develop self contained UI gadget in some ways like portlets.. Is
this a completely wrong idea or can be useful?

Yes, you can theoretically invoke web services exposed on your server
directly from GWT client using the GWT HttpRequestBuilder.
In practice this is almost certainly an unfavourable option because
SOAP is a bloated over complicated XML based data exchange mechanism

Thank you for the tip.. I've looked around the Web for days and I'm
gaining a clearer view about technologies and possible
architectural solution for my requirements.
I'm especially doubtful about the possible integration of techonlogies
like GWT on the GUI and an ESB like servicemix.

Your authentication would be better handled outside of GWT (i.e; SSO
or form-based login). But for the application itself, that approach
sounds reasonable. By putting the SOAP client in a servlet, you have
access to a wide range of libraries that you can use to interact with
the SOAP services,
Great! Thank you.

Hello. My project is about designing an online social network
application. I'm in a first stage of evaluating different
architectures and design alternatives. The user interface should be
made using GWT and the architecture should be a SOA and/or EDA.
Now, I'm new to all these
Service Oriented Architectures are about connecting different systems
within an organisation together using, typically, SOAP. An SOA usually
uses a message hub, often called an Enterprise Service Bus, of some
kind to manage the connections and SOAP calls between systems. Axis is

future.
