Hi Radim,
It's great to get your feedback on this. Your posts to the user list
(including those with "tough" questions, like Java2WSDL and "on the fly"
WSDL generation :-) have been much appreciated.
I am currently working on asynchronous support for callbacks.
The @OneWay part of async is already working in the current trunk and
we just need a test case for it, which I will add when I have got
callbacks into reasonable shape. At the moment I am working on
TUSCANY-1496 which will greatly simplify the callback implementation
by treating callbacks almost identically to forward calls both within
the core framework and within binding extensions. I am also looking
at TUSCANY-1347 and TUSCANY-1500 which relate to slightly more advanced
use cases for callbacks including some gaps in our support for the
full Java API for callbacks.
Callbacks and conversations are intimately connected and SimonL and I
have had one discussion about this and some of the spec points that are
not 100% clear. I'm expecting to work with SimonL to bring together
his work on conversations with my work on callbacks, and to have full
support in the 1.0 release for both callbacks and conversations (and
the interactions between them). This support would include the core
framework as well as the Web Service binding.
After this is all taken care of, I would be very interested in putting
together a sample of the type that you describe with complex POJO types
(which I would like to represent as SDOs) and Web Services. This would
require getting the SDO tooling story sorted as well. Of course,
someone else might get to this one ahead of me :-) I would be interested
to know whether this would meet your requirement, or whether you are
specifically looking to pass around non-SDO POJOs.

Hi Ant,
the top priority regarding web services would be having "on fly"
generation of WSDL, without the need of having to supply own file.
Axis2 can do it for its services described in services.xml file. It
would also help if there was a working example that would use complex
POJO types as parameters and results of a service call, deployed as a
web service, as I am struggling to make this work. It is not clear to
me if I need to supply services.xml or not for Axis to make complex
types working (register serializers/deserializers).
Also important are following items in your list, however, not as
important as the above issues. The items are ordered by priority.
- WS Security
- Sort out our WSDL tooling story - get SDO integrated into Axis2?
- asynchronous services
- conversational services
Thanks a lot!

Note that its likely we wont have time to get everything listed there done
in 1.0 so please say which things are important to you to help us prioritize
what does get done.

Hi Jean-Sebastien,
where is the SCA Java Releases wiki page which lists some work
items in ws binding space, that you mentioned?
Thanks,

Bringing this thread up again as time is ticking on if we want to get
a
release out this month. How would people feel about taking a branch
for this
release in a bit less than 2 weeks, say aiming for the 14/15th of
August?
That should just about give enough time for clean up and voting to
get a
release out by the end of August.
Another thing I wondered about was the name, we've been talking about
this
being 0.92, how about something higher to show we're getting closer,
maybe
0.95 or 0.98 or even 0.99? (that prompts a what/when is 1.0, I'll
start a
separate thread about that)
...ant
What/when is 1.0? Good question :) There has been a lot of progress in
the recent 0.90 and 0.91 releases and I agree that Tuscany SCA is
getting close to a 1.0 release.
So, let's start discussing "What is Tuscany 1.0". I'm moving this thread
to the tuscany-user list as I'd like to get feedback, requests and ideas
from Tuscany users.
Speaking for myself, here's some thoughts on what I'm interested in
having in a 1.0 release:
* SCA assembly spec 1.0 support
Looks close to complete here, I think it just needs a little more
testing and a simple implementation of a distributed domain. Simon seems
to be making good progress in that area. Also I'd like to have a simple
admin console to add/remove contributions and composites and allocate
components to nodes.
* SCA Policy framework 1.0
Modules policy and policy-xml are taking shape. Having one concrete
policy like Security implemented on top the framework would be good.
Maybe Venkat could give his thoughts on this?
* Extension points for component implementations, bindings, databindings
and policies
SPIs need a little cleanup as they're starting to carry a number of
deprecated interfaces/methods. There's no extensibility mechanism for
policies yet but it shouldn't be too hard to add that with a pattern
similar to the existing extension points.
* SCA Java APIs and Annotations 1.0
Almost complete, just missing a complete implementation of
ServiceReferences and a few conversational annotations. I'd like to
refine the SCADomain.getService() API too. Also, on a separate but
related note, a better Java proxy (better than a JDK proxy) would be
great, I've seen a Cglib proxy contributed recently, how about extending
that idea to all proxies?
* Spring component implementation
This looks in a good shape. Mike, what else are you planning to do
there?
* WS binding
What is left to do? The SCA Java Releases wiki page lists some work
items in this space, which ones do people think should be done for a 1.0
release?
* JMS binding
Seems to partly work but will need a little more to align with the
latest spec. Anybody interested in helping with it?
* Feed and JSON bindings
IMO important to have to integrate with Web 2.0 apps. The Feed binding
is fine as far as I can tell. What do people think remains to be done
for the JSON binding?
* Scripting component implementation
I've been a happy user of < implementation.script> but have not tried
using complex types and much integration with bindings. What's left to
be done here?
* Geronimo integration
I'd like to be able to deploy SCA contributions to Geronimo, looks like
there's good progress on that front. I'd also like to support the
integration of Webapps in SCA compositions as <implementation.web>
components.
* Docs
Our architecture docs could use some improvements and cleanup :). For
user docs, what do people think about developing more tutorials and
variations around the Online Store tutorial?
* Samples
Some of them need minor cleanup. Are we missing samples in any specific
area?
* Other implementation and binding extensions
We have starters or partial support for <implementation.notification>,
<implementation.bpel>, <binding.ejb>, < binding.rmi>,
<implementation.osgi>. Could people help get these extensions in the
release?
Thoughts? Anything people would like to discuss and get included in
Tuscany SCA 1.0, please bring it up...
