Even though 'Service' comes first in SCA (Service Component Architecture),
SCA is a distributed component model. It's about designing components (and
composites) rather than designing services. It doesn't feel like it was
designed to build a SOA. It feels like its main goal was to define a
distributed component model. And as we all
know, the distributed component models failed in the past. I think SCA will
too.
For the second day of JavaOne my schedule contained technical sessions and
BoFs about mostly SOA, SCA, REST and Comet.
SCA
I attended two more sessions about SCA:
- Open-Source SOA with SCA and Apache Tuscany
- Open Standards for SOA and Java technology
The second one was a panel session. The host was MC David Chappell of
Chappell and Associates and the panellists were David Chappell of Oracle,
Mike Edwards of IBM, Steve Jones of Capgem... (more)

Java SE 6 and Java SE 7
My first technical session was about Java SE presented by Danny Coward from
Sun. It was about the current situation of Java SE 6 and the roadmap to Java
SE 7. The talk started with a few encouraging stats. For example,
Java’s performance increased 220% between Java SE 5.0_04 and Java SE
6.0_05P. It’s always nice to hear this kind of good news.
One of the great news about Java is that it has a full open-source JDK now.
Some parts of the JDK couldn’t be open-sourced due to licensing
restrictions. And this situat... (more)

As Service-Oriented Architectures gain ground, it becomes obvious that their
performance is the key to their success. I'm going to briefly write about two
sessions that I attended in JavaOne 2008. They outline two totally different
approaches from two very different companies. You're going to see that a well
performing SOA implementation requires considerable work and performance
tuning expertise.
