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.

JavaOne 2008: SOA and Performance

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.

JavaOne 2008: A Day One Report From the Sessions
