Thanks Anne, I did some reading up on the
subject myself. But the URL that you had posted is more useful.

SCA =
Service Component Architecture
See http://www-128.ibm.com/developerworks/library/specification/ws-sca/
"Service Component Architecture (SCA) is a set of specifications which
describe a model for building applications and systems using a Service-Oriented
Architecture. SCA extends and complements prior approaches to implementing
services, and SCA builds on open standards such as Web services."
The spec was developed jointly by BEA, IBM, IONA, Oracle, SAP, Siebel, and
Sybase.

If J2EE was still birth, that makes JBoss what?
The best instance of

JP - Java hit alpha2 in november of 1995. I know
because I quit
my "stable" job to do full time Java
consulting that month. Java had
a nice life - and will continue to have a nice
life. As languages
mature so does their ability to innovate due to
legacy customer
constraints. No big deal - just how things go.

SCA cleans up J2EE API mistakes, it binds
components and services,
introduces encapsulation for DSL's and provides a
uniform data
model. Nothing is perfect, but SCA represents the
innovation that
we've seen at the open source level
(Spring/IoC/etc.) taken to the
next level and packaged by major vendors, enabling
Very Large
customers an easy buy/support model.

Like I didnt' hear that about Java in 1996 :-)
You can continue to tell your customers to NOT use
SCA or Ruby and
to find innovation in JBoss and Java 5.0. Your
call.
I will tell my customers to leverage coarse
grained services that
are loosely wired together, leveraging a component
model containing
domain specific languages. And that they should
use the most dynamic
and participative presentation and collaboration
framework available
to them, regardless of the language. IMHO, failure
to acknowledge
the Ruby advantage and associated movement is a
mistake.
Now, many of my customers will not be able to make
the
WOA/SOA/SCA/DSL transition anytime soon. That's
cool.
JBoss/WebSphere/WebLogic and are just fine for
stabilized
environments. More agressive shops will likely
look at
Spring/Hybernate/etc. And even more aggressive
shops will do
WOA/SOA/SCA/DSL. I.T. shops that do not seek
advantage or innovation
will likely not seek change.
I'm glad we agreed on 'peace on earth' and 'good
will to men' ;-)
