There has been quite a bit of activity over the last
month-and-a-half enhancing the Kernel. Based on this work, I'd like
to cut a release of Kernel, the Standalone Runtime, the Webap
Runtime, and the Maven iTest Plugin as a stepping stone to having a
1. release. I was thinking we would call this release "1.0 alpha".
I see this "alpha" as evolving into a series of iterative releases
over the next month where we introduce some of the more "compelling"
features we have been discussing related to service networks,
federation, and deployment. The primary goals of the first alpha
release would be centered on enhancements to the programming model
that have been introduced with the recent Kernel changes.
Specifically, the alpha would provide an enhanced version of Kernel
that our users can experiment with, extend and provide us feedback
on. This will assist us in validating he programming model supported
by Kernel.
The key features of the alpha release would be:
1. SCA 1.0 APIs
-Support for many of the new SCA 1.0 Java APIs
(ComponentContext, Conversational annotations)
2. An enhanced standalone runtime with JMX support
3. An enhanced and SCA 1.0-based model for integration testing
(elimination of SCATestCase, which is not spec-compliant
4. Simplified wiring
5. Simplified extension model
6. Architecture for support of federated deployment
7. Support for web applications using SCA 1.0 concepts
I'd like to follow the alpha with additional releases that introduce
additional support for federation, deployment, and the SCA 1.0 APIs.
To stage this, perhpaps we the following in the next release after
the alpha:
- Contribution service
- Refactor of Databinding (mentioned in a separate thread)
- Introduction of master/slave nodes and federated wiring
- More complete support for conversational APIs, including
ServiceReference
In terms of work items, I think we need the following (besides a
stable kernel :-) ):
1. Standalone runtime operational and able to deploy application and
extension SCDLS
2. At least two samples. I propose the Calculator Sample (Standalone
and Web app) and the Loan Application Sample
Feel free to suggest additional features. As a general principle,
I'd like to get a release out sooner rather than later with "big"
features introduced in the consecutive releases mentioned
previously. One thing I'd like to see if we can fit in but may have
to cut is the new PhysicalComponent builders. That may be something
we stage later.
Hopefully, we can cut the release this week.
Thoughts?
Jim

I think it will be good to have a stable kernel. Which level of SCDL
and which features from the SCA assembly model are you proposing to
support in that kernel level?
As it says, SCA 1.0 level - not all of it for sure but a baseline for
itest, standalone and webapp environments.

A baseline? Do you have an idea of which features from the SCA assembly
model? includes? nested composition? wiring across composites? promotion
of services? complex properties or not? which databindings? any support
for WSDL? any support for configured implementations?
