my questions for used / important / generally functions has as context the
see on the architecture!
i'm excited "fan" of clay and its features given to developer - and shale
other features. so the presentation part of application is clear.
but the business logic is the fact...
i mean especially the gap between ejb 3.0 and shale models
It encompasses the kinds of patterns that I would
recommend for building new apps today.
1. i followed your thinking about the example an the port from struts and
thats right, but lets talk about you last statement. your experience is more
great than my - so maybe underline your statement!
2. as i asked in another mail - all talk about ejb 3.0 and the jpa is built
upon ejb 3.0.
so if already use ejb 3.0 for persistence or jpa - whats your opinion about
mix or share business code in the shale model objects and in
stateful/stateless ejbs.
3. what do you think about the basic approaches of shale and struts - i know
you leaded both - so would you built an framework like struts again, with
the knowledge of what shale can perform.
4. is shale an addon to jsf or the next jsf? ;-) and how will be handled
overlaps between shale and jsf 1.2 (i think for @PostConstruct in comparing
to shale livecycle) - because you told shale is independent for all jsf ri
and you will test with 1.2 which is part of java ee from 11.05.06
thx

To me, trying to pick the most important *methods* is a little bit too
fine
grained to be useful, because different applications have widely varying
needs. Instead, I would tend to focus first on the architectural patterns
that a particular framework enables, and then see if that matches up to
your
application requirements.
In the case of Shale, I would suggest looking at the
"shale-mailreader-jpa"
example application. Functionally, it is the same as the good old Struts
example app that has been around for almost six years now. But, this
implementation uses JavaServer Faces and Shale for the view tier, and Java
Persistence Architecture (JPA) for the model tier (although you could
easily
substitute Hibernate). It encompasses the kinds of patterns that I would
recommend for building new apps today.
