So I was preparing the data for this website locally on my machine. My staging environment was pretty much the same (same Java VM, JBoss AS, MySQL version, etc.) The only difference is the operating system, it's OS X and the live site is running on CentOS. I created a package to deploy and everything looked fine. Until I edited documents on the live site. MySQL started to throw constraint violation errors it didn't show in the staging environment.
Three months to the day after the release of Seam 1.2.1, Seam2 has entered its beta phase. The Seam 2.0 codebase is more robust, better organized, better documented and is designed to take Seam beyond the world of JSF. Seam 2.0 introduces the following changes and new features:
As predictable as fog in San Francisco, every couple of months we are unsurprised to see yet another announcement by some company or open source group who has solved the complexity of Object Relational Mapping (ORM) by eliminating the relational database. Great leaps in developer productivity are promised, together with astonishing performance increments, usually in the realm of two or three orders of magnitude compared to existing technology. What is most amazing about this is that so many different groups seem to have achieved such breathtaking advances entirely independently of each other and yet, paradoxically, enterprise adoption of these technologies remains approximately zero. What's going on here? Is the all-powerful Oracle Corporation secretly blackmailing all CIOs in America? Well, let's try to understand this paradox better by taking a closer look at the claimed benefits of these systems.
Tomorrow (Wednesday) morning at 9:30, Bob Lee and
I will talk about the work in progress on JSR-299.
Over the last couple of months, we've been working
with the rest of the Web Beans expert group to create
a component model that combines the best of Seam,
Juice, JSF and EJB 3.0. The end goal is the
definitive programming model for business logic
components in Java, combining Seam's state management
with Guice's typesafety.
With the new Groovy 1.1 beta out and its support for Java 5 annotations, wouldn't it be great to be able to write Seam applications in Groovy?
Indeed it is great and you can do that with JBoss Seam (in CVS HEAD at the time of writing).
