Re: SCA Tools
Jim :-))).. Please help me understand the scope of "not required". If something is not required then why have it in the first place? Are these things no longer relevant to the current Tuscany-Java?

Re: Can't do multiple import.sdo's
Hi Elizabeth, do you have a test case for this and I'll take a look. Regards, Kelvin. On 31/07/06, Elizabeth DeLouise <[EMAIL PROTECTED]> wrote: A problem I came across (not sure if it's on my end or Tuscany's), was that I could not have more than one tag in my sca.module file. If is used more than once, only the first wsdl specified is used to register sdo types. The hack I came up with is to copy-paste the type definitions from one wsdl into another, and declare them like this: File1 contains type definitions from both File1 and File2. Both files must still be imported using import.wsdl for this to work, and using import.wsdlmore than once IS successful. Big Bank appears to use 2 import.wsdl tags, as well as I'm not sure if this gets around the problem of registering SDO types or not. Does anyone have any thoughts on why import.sdo can only be used once? -- Best Regards Kelvin Goodson

Re: Axis2 Test generator
Hi David, yes this sounds like something that could be useful. How do you plan on generating the dummy data? There's already some code for this that Venkat has done for creating empty XML instances from a WSDL, see TUSCANY-419, hopefully you'll be able to reuse and enhance that code. ...ant On 7/31/06, David Wheeler <[EMAIL PROTECTED]> wrote: Hi, I've been working, with Raymond's help, on a system to generate a test based around a given wsdl.

Does this sound like a good idea? Thoughts? -David Wheeler.

Tuscany weekly IRC chat log (July-31-2006)
Here's the IRC log from yesterdays scheduled chat.
The main things talked about were what happened with Tuscany at OSCON (the
talk was ok, not so many at the BOF). That Tuscany has a new website was
mentioned (go have a look!). Most of the rest of chat was about modularity
and releases related to this email thread:
http://www.mail-archive.com/tuscany-dev%40ws.apache.org/msg05658.html
I think it sounds like most agree a single monolithic download of everything
and all the dependencies could get real big. I think there was some
agreement that being able to build individual parts or specific
distributions from a src release would be good. Hard to summarize what else
was said on this, probably best to go read the chat and emails.
(other discussions were going on before and after this scheduled chat, i'll
get summaries of those posted in separate emails)
it's 8:30 - how about we pick this up after?
componentType [{http://www.osoa.org/xmlns/sca/1.0}componentType]
* kgoodson_away is now known as kgoodson
sure ok , if there's other things to talk about
just wanted to give others a chance :-)
there's stuff like comments from oscon
there's a couple of mail threads
the website went live
anything else interesting happening?
well no one is speaking up ... getting some
extensions/containers/bindings to go is top of my list right now
it would be great if we could hear little bit from the folks that
went to OSCON
yup
also how about what to do about Tomcat or Jetty as thats come up on a
few threads now
I'd say it was a fairly quiet conference
lots of talk about open source; a lot of the technical stuff was
on stuff like Rub
Ruby
there were about 80-100 people in our session
80-100 is a good size for OSCON size ?
our BOFs were quiet - just a couple of people from outside the
project
the room was about 2/3 full which isn't bad I think
hi, sorry, was on the 'phone, my perspective was that the people
I met were more interested in programming language advancements (ruby,
rails, ...) than broader programming architectures
* Venkat has quit IRC (Read error: 110 (Connection timed out))
yeah
It was also quieter than I have seen in the past
I have to go right on 5:30, if oscon is done could we move on to the
next topic?
yes
great stuff with the new website rick and everyone involved
I have a spec call at 9 so may be a little distracted as well
many contributers
sorry did not get it up for oscon
thanks for doing it
lresende has mentioned it on our blog so some people will notice
which of the open email threads did you want to discuss Jeremy? or can
i start asking more extension questions now?
we need to keep updating the website - keeping the content fresh
what about the modularity thread?
change the background color ? :-)
i plan to expand the SDO java stuff as my next activity, i'm
just trying to complete a paper on SDO as soon as I can, and I expect that
work to produce some useful material for the website
any thoughts on modularity?
ok, with having more separate releases isn't the incubator voting
going to be an issue?
* halehM has joined #tuscany
maybe - I think it will depend on how much and how often
if we get the legal issues sorted out then it really comes down to
our mentors
so, with this modularity, you want to acomplish components
releases ? like SCA releases not together with SDO releases ?
the C++ M1 took ages and only happened when I went bothering people.
If we have even a few more individual releases for Java
modules/distributions I think it will get real hard to get the votes
I'm not sure the two are directly related
C++ and Java that is
ok
yes
btw, did we get the C++ M1 released ? i don't see it mentioned on
the website... (download page)... and if so, i wan to post a note on the
blog as well...
(opps, wrong window sorry)
just done today
i see, thanks...
by more modular are we talking also breaking sca down more ?
webservices ajax bindings tomcat, standalone ?
both - proposal 1 was to allow separate releases of sdo, das, sca,
etc.
proposal 2 was to support breaking down sca
proposal 1 seems ok to me but sca might still have sdo and das in
it ? or you want to keep it totally seperate?
no, I think sca could include those
It would be a good idea to have the 3 separated
or perhaps the sdo databinding part of sca would include sdo
but I don't want sdo have to wait for sca or vice versa
IMO I think proposal 1 sounds good something I thought we'd always
mature to anyway.
* Venkat has joined #tuscany
any other thoughts?
* kg has joined #tuscany
* kgoodson has quit IRC ("Chatzilla 0.9.73 [Firefox 1.5.0.4/2006050817]")
maybe we need to give others (including the SDO +DAS guys) a chance to
reply to the email thread
* kg is now known as kgoodson
Jeremy, your proposals complement one another. These are not
intended to be separate proposals that compete. Right?
right, it's one set of four
ant: yes, not planning on rushing into anything here

Are these things no longer relevant to the current Tuscany-Java? Jim is echoing a goal that SCA should be simple enough to use and configure that additional tooling should not be required. For example, I should be able to look at a SCDL file and understand what it is doing, or I should be able to work with simple Java classes and have the runtime figure out what to do. That's not to say that tooling cannot help - a specialized tool can make that SCDL file easier to view or edit, an IDE can make editing Java easier. But tools should be there to assist rather than be required because the underlying technology is so complex. Take for example, java2wsdl. If I am a simple Java developer, there is a good chance I do not know WSDL and have no interest in being forced to learn it. But the machinery here needs WSDL to interoperate with other systems. We can put WSDL in the user's face by having a tool that generates WSDL that they need to run as part of a build; alternatively, we can have the runtime handle all the WSDL stuff under the covers leaving the user in their Java comfort-zone. I think the latter is better, although we will still need the tool for those users who do want to use WSDL explicitly. -- Jeremy - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]

Re: Composite classpaths, was: How to use extensions with the standalone launcher?
On Jul 31, 2006, at 11:42 PM, Jim Marino wrote:
An end user application developer could write some type of library
that gets reused by different composites. We should have a
mechanism that supports this without resorting to maven. I think we
should have some type of resolver abstraction, one implementation
being a maven downloader.
I agree.
We need an abstraction for "dependent artifact" and a way of locating
and resolving them; using a Maven repository would be one concrete
implementation of that abstraction.
There are a couple of other options we could also provide, based
off of OSGi semantics:
1. Allow a jar to specify its dependencies using "pure" OSGi
manifest entries when the composite is packaged as a bundle and
deployed to an OSGI environment
2. Allow the SCDL to specify dependencies using OSGI semantics.
These would then be "baked" down to whatever packaging the host
environment supported, perhaps through a pre-deploy step
3.As part of #2, have a way to specify a maven bundle and have
the pre-deployer pul it from maven and repackage it.
Generally I don't like pre-packagers but that may be the price
people have to pay for deploying on host environments with
problematic classloading semantics - e.g. J2EE app servers. In an
OSGi or jar launcher environment, things should just work without
a predeploy step.
These seem like alternatives. If the user wants to use OSGi
semantics then this would be a way to support them. However, there
are a lot of things out there that do not have OSGi manifests and
we need to be able to support them two.
That's what #2 would be used for as it is not dependent on OSGi
artifacts such as bundles. A SCDL artifact would specify the
dependencies and they could be resolved to whatever physical
packaging the host platform supports/
This seems like it can be implemented on top of a repository for OSGi
artifacts or a repository of Maven artifacts - this sounds good.
Also, these only work if the composite is packaged as a bundle and
I think that it's important to allow people to deploy composites
that are simple XML SCDL files (no archive involved). That means
we need a way in the SCDL to be able to specify what the
dependencies are.
#2 could also work with a file system through some type of "custom
resolver" mentioned above.
So the key here is the abstraction for artifact resolution. The
interface I had proposed before was:
interface CompositeRepository {
URL locate(String name);
URL locate(String groupId, String artifactId, String version,
String identifier);
}
We probably need to extend this to capture the formal concept of an
Artifact so I would recast this as:
class Artifact {
String group; // a conceptual grouping of artifacts such
as publisher
String name;// the name of the artifact
String version; // the version of the artifact
String classifier; // a classifier such as hardware platform or
language
boolean optional; // whether the artifact is required
}
class ResolvedArtifact extends Artifact {
URL url;// a URL where the artifact can be obtained
(typically a file: URL)
Collection dependencies; // list of
dependencies the artifact has
}
interface ArtifactRepository {
ResolvedArtifact resolve(String name); // lookup based on a
simple string supplied by the user
ResolvedArtifact resolve(Artifact artifact); // lookup based on
explicit information
}
I think this is general enough to cover both Maven and OSGi artifact
naming schemes (and hopefully more).

[ANNOUNCE] Tuscany C++ Milestone 1 Release
The Apache Tuscany community is pleased to announce its first C++ milestone release. You can download binary and source distributions from: http://incubator.apache.org/tuscany/downloads.html For further information, visit our web site at: http://incubator.apache.org/tuscany Introduction Tuscany C++ provides a C++ implementation of the Service Component Architecture (SCA) and Service Data Objects (SDO) specifications. For pointers to the specification documents, visit our documentation page at: http://incubator.apache.org/tuscany/documentation.html Incubation Tuscany is an effort undergoing incubation at the Apache Software Foundation (ASF), sponsored by the Web Services PMC. Incubation is required of all newly accepted projects until a further review indicates that the infrastructure, communications, and decision making process have stabilized in a manner consistent with other successful ASF projects. While incubation status is not necessarily a reflection of the completeness or stability of the code, it does indicate that the project has yet to be fully endorsed by the ASF. Release Summary = Tuscany SCA C++ provides a runtime implementation for the Service Component Architecture 0.9 Assembly Model and C++ Client and Implementation specifications. Key features include: - Module assembly using SCDL - Support for C++ component implementation types - Component interfaces described by C++ classes - Axis2/C Web Service binding for EntryPoint and ExternalService - Sample demonstrating wiring, service location and invocation between C++ components Tuscany SDO C++ is an implementation of the Service Data Objects 2.0specification for C++ developers. Key features include: - Dynamic data object support - Type loading from XSD Schema - XML serialisation/deserialisation - Helper classes (XMLHelper, XSDHelper,DataFactory, etc.) - Simple example programs Please feel free to send any feedback to our mailing lists: tuscany-dev@ws.apache.org tuscany-user@ws.apache.org Any contribution in the form of coding, testing, improving the documentation, and reporting bugs is always welcome. For more information on how to get involved with the development of Tuscany, visit our Get Involved page at: http://incubator.apache.org/tuscany/get-involved.html Thank you for your interest in Apache Tuscany! -- Pete
XPath 2.0 engine?
The recursive changes include support for complex properties accessed via XPath 2.0 expressions and the only XPath 2.0 engine I have found is Saxon (http://saxon.sourceforge.net) - others such as the one in the JRE and Jaxen only seem to support XPath 1.0. I have a couple of concerns over Saxon due to the MPL license and the dual-licensing they use to support a commercial implementation - does anyone know of an alternative? -- Jeremy - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]

Re: Webservice via Axis2 in Tomcat.
I think there's a difference. Web services play a prominent role in the SCA specs and are likely to be used by most people which makes a good case for including them in distributions by default. The JavaScript stuff, although useful, is not something covered by the spec at all and is likely to be used by a different audience. For those, I would suggest that we should create a new distribution, one aimed at people doing REST, JSON, JavaScript stuff; that may or may not include web services depending on what users want. That would give us three distributions: * standalone environment * web-app environment with web services * web-app environment with JS-type stuff -- Jeremy On Aug 1, 2006, at 9:57 AM, ant elder wrote: How about the JavaScript container be included by default as well then?

Introspection of JavaScript components
I've had a go at adding support for introspection of JavaScript components
and wondered if anyone had any comments.
As JavaScript is untyped and doesn't have the concept of annotations its not
possible to have this work as well as with Java components. How I've done it
is to have the script define a object named SCA which defines the component
configuration.
There's a sample introspectable script at:
http://svn.apache.org/repos/asf/incubator/tuscany/java/sca/containers/container.javascript/src/test/resources/org/apache/tuscany/container/javascript/function/IntrospectableHelloWorld.js
There'd be nested objects defining any references and properties, and WSDL
interfaces could be described something like:
SCA = {
'wsdlServiceName' : 'myservice'
'wsdlPortName' : 'myPort'
}
Comments? I think this makes script components simpler than using the
.componentType side file, but what do others think?

Re: Webservice via Axis2 in Tomcat.
I mostly agree, but one of the big benefits for Web services is the JavaScript E4X support. With that and when TUSCANY-419 and the magic databinding stuff is done this is going to make JavaScript components really really useful to use with WS i think. All the old WS debates about databindings and XML to Java mappings disappear as XML becomes really easy. ...ant On 8/1/06, Jeremy Boynes <[EMAIL PROTECTED]> wrote: I think there's a difference.

Re: Webservice via Axis2 in Tomcat.
There is also the bridge scenario where people are using JSON to talk to Ajax clients for the UI but want to access back-end services that are using SOAP/HTTP or SOAP/JMS (or XML over JMS ...). I think this is why we need a spectrum of distros determined by user scenarios. By the time we throw everything in that anyone might want to use then the kitchen sink variety will be huge, giving a false sense of complexity that will put people off and will be a nightmare to release as it will require syncing up all the plugins. The other extreme is a minimalist one with nothing in it but which allows/ requires people to figure out and add in function that they need. I don't think either of these is ideal. What I've been proposing is a set of distros based on common runtime platforms that people will use. The ones so far are a standalone (J2SE) platform and a web-app (J2EE) platform; there's been some discussion of a Tomcat platform (i.e. Tomcat + SCA enhancements) like M1, and another would be a Celtix platform. These are somewhat exclusionary - for example, we will not need to include the Tomcat integration code on non-Tomcat platforms, it's just not relevant. I think users will use these differently, for example, using the standalone one as a client, Tomcat for web-app development or Celtix for integration. The different usage patterns will show us which extensions are relevant for that pattern and we can include those in the distro (reducing the number of things users need to add or remove). -- Jeremy On Aug 1, 2006, at 10:16 AM, ant elder wrote: I mostly agree, but one of the big benefits for Web services is the JavaScript E4X support.

Yea this is definitely simpler than a side file. I came across this
but never tried it out a few years back:

Apparently it provides a way to "introspect" the script to retrieve
Javadoc style annotations but the way you have may be better and
simpler.

Re: Build and distribution modularity
Maybe we should take a conservative approach initially (and this is probably something similar to #3, #4). As long as milestones are not too infrequent then I think we can release the three subprojects on the same schedule. Users should be able to easily pull SCA , SDO and DAS components independently from a distribution. Also, it does not seem too much an inconvenience for those interested in working from the head to pull and build the entire project. --Kevin Rick wrote: In theory I like what you're saying Jeremy, but in reality I'm kinding of siding with Ant concerns. Not sure how it will scale as we add may extensions and all the possible combinations. Also all the distros add administration, documentation, issue tracking etc. I certainly can see a separate SDO and possibly a separate DAS distro as I can see the use case for that and it easily explained to the end user why they are a separate distro for them. With regard to SCA I think a goal of building them separately is good, having some test that just run with each extension is good.

Re: Webservice via Axis2 in Tomcat.
It seems like having the build infrastructure make it really easy to configure what components go into a distro would help us iterate our way to the "right" number and makeup of distros. While the POM and project structure manipulation required right now isn't particularly difficult, it could probably be a lot easier -- I'm thinking of some mechanism where the POM dependency and assembly descriptor XML fragments associated with each extension can be kept with the extension, and the distro description just has to reference extensions by name.

By the time we throw everything in that anyone might want to use then the kitchen sink variety will be huge, giving a false sense of complexity that will put people off and will be a nightmare to release as it will require syncing up all the plugins.

What I've been proposing is a set of distros based on common runtime platforms that people will use. The ones so far are a standalone (J2SE) platform and a web-app (J2EE) platform; there's been some discussion of a Tomcat platform (i.e. Tomcat + SCA enhancements) like M1, and another would be a Celtix platform. These are somewhat exclusionary - for example, we will not need to include the Tomcat integration code on non-Tomcat platforms, it's just not relevant. I think users will use these differently, for example, using the standalone one as a client, Tomcat for web-app development or Celtix for integration. The different usage patterns will show us which extensions are relevant for that pattern and we can include those in the distro (reducing the number of things users need to add or remove). -- Jeremy On Aug 1, 2006, at 10:16 AM, ant elder wrote: > I mostly agree, but one of the big benefits for Web services is the > JavaScript E4X support.

Scope factory initialization: svn commit: r427726 [1/2] ...
Ken,
I think the factories should wait until their init method is called
otherwise they are registering before they have finished being
initialized. This also allows a "this" reference to leak before the
object has finished being constructed (i.e. it could be invoked
before it is fully instantiated). This problem is in all the recent
scope factory changes.
Will this fix the issue Ant mentioned yesterday where leaving off
@Scope("MODULE") gave a NPE?

Just so's I understand what you're saying -- the problems you're

scope factories are trivial in their "construction" (ie, the ctors
don't do anything, nor do the init methods), any races between
ctor/init completion & other code calling into the factory aren't
actually a problem (given the super class's ctor will always be
completed).
That said, agree the code should always do the right thing :) My
understanding of component instantiation is ctor followed by init
method -- so we could store the injected ScopeFactory in the ctor and
do the register call in the init, and then clear the injected
ScopeFactory reference (avoiding circular references). Is that what
you're suggesting by "waiting until their init method is called" ?
Jim & I also discussed a more complex solution involving making the
scope registry "watch" for newly created scope factories and register
them, but given the seriousness of the problem, having some solution
checked in seemed expedient.
BTW, does @Init work with inheritance? Ie, if my super-class has a
method marked @Init, will that method get called before my @Init

Yea I think having the registration done in init() is better due to
an escaping this reference. @Init will be called after the ctor is
and all injection performed so it's safe to do that.

As I understand it, today this is definitely not true -- hosts such as the Launcher and SCATestCase are strongly coupled to implementation classes coming out of the runtime libraries via their system.scdls. It seems like changing this would imply that the the runtime libraries would include a "core" set of system SCDL definitions that would be leveraged by all hosts, and any host that wanted finer-grained control would continue to remain tightly coupled? Also not sure how this would work for extensions -- since so many of the SPI elements are abstract classes and not just interfaces, it seems it would be hard to keep impl changes in such classes from being visible to extensions. Users want distributions to be something that they can download, install and use for some purpose. We will build distributions with such a purpose in mind and include within them everything that a user would need to achieve it. For example, one purpose might be a client- side install so we would include within that the minimal runtime plus commonly used client bindings (e.g. web services); another purpose might be for building web applications so we would produce a distribution aimed to support web server functions (which may or may not include a server platform); another might be as a service intermediary which may have a very rich set of bindings. All distributions will support some form of extension mechanism that allows users to add functionality by installing extension modules. These modules will be released and distributed separately. Some may be included by default in some distributions (e.g. web services). +1 to this philosophy of distros. In particular, I think we want to have a system where getting and installing extensions is super-easy a la maven plugins or ant tasks -- no one really worries about whether extensions to those programs "ship" with the default distro, since it's so easy to add them afterwards. Ant's earlier concern that not being in a distro might make an extension "2nd class" is definitely something we want to avoid, but I think the right way to do that is to make post-facto inclusion really easy rather than including more extensions by default.

I don't think so - once you call register, another thread could call

Agreed. Jim, Sebastien and I had discussed mapped multiplicity
references before as well. The application here would be the registry
having a multiplicity reference of type Map whose members would be
automatically managed by the fabric. As eligible services came online
(based on rules associated with the reference) their key would be
extracted and they would be inserted in the Map.
BTW, does @Init work with inheritance? Ie, if my super-class has a
method marked @Init, will that method get called before my @Init
method?
I believe there can only be one method marked @Init across the
implementation and its superclasses. Normal Java method overriding is
followed (so if you override it your declared method will be called
and it is your responsibility to call the superclass method that you
override).

How about moral support - I'm swamped ;-) Seriously, you may want to sync with Jervis since he mentioned reusing some pieces across Axis2 and Celtix.

I don't think it does it automatically - I always have to set it manually before checking in. I typically do an "svn st" before committing just to make sure that there is nothing missing. It doesn't always work - for example, if you've cleaned there won't be a target directory which is a common indicator that svn:ignore is not set. -- Jeremy - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
Re: How to use extensions with the standalone launcher?
Hi Jeremy,
Why not name them as extension.scdl. Though for most parts they might be
treated as any other scdl some where we treat them a little differently as
in adding them to extensions and so on. Infact a solution developer could
develop some extensions and applications and keep them all bundled
together. When deployed the SCA runtime is able to understand which ones
are application scdls and which ones are extensions scdls and treats them
accordingly. That way the SCA installation directories can be left alone
i.e. the user need not drop the extension jars in a predefined dir. and so
on.
Also am curious about the name 'default.scdl'. Why 'default'? Is it to
imply that these scdls will be automatically picked up and deployed? So can
I give other names to my scdls and if so is there a programming model to
explicitly mention about them or load them?
Thanks

How about until we have a way to do extensions properly to fix the problem
Matthew is seeing the testcase could determine which is the application
default.scdl by seeing if the resource URL starts with the current working
directory which it can get from System.getProperty("user.dir")?
