Re: Simple way to run Tuscany from source distribution?
Probably, a possible way to accomplish this would be to make the ant scripts more flexible, and lookup the distribution based on a user defined configuration. This way, you could get a distribution and define where it is in your build properties and that would be used by the ant scripts and allow you to build and run from source distro or trunk.

Re: Tuscany plug-in and Eclipse 3.4
Hi Leucir We have been using the Tuscany plugin in both Eclipse Europa and with some recent changes in Eclipse 3.2 as well. I'm assuming that by Eclipse 3.4, you mean Eclipse Ganymede, and if so, I'd recommend that you use a GA version such as Europa. I gave Ganymede a quick try and was having some issues even with basic functionality in the java perspective. Please let me know if it does not work for you in Eclipse Europa.

Re: Web Service References
Hey Jean-Jacques Dubray Let me try to respond your questions : The helloworld.composite defined in the itest/bpel/helloworld-reference defines a GreetingsServiceComponent that is implemented by a simple pojo and has its interface contract defined by a wsdl, in this case greetings.wsdl. This component does not use the binding.ws, thus is not exposed as web services. The helloworld-ws-reference does use the binding.ws to wire to the service exposed by the helloworld-ws-service sample.

Re: Web Service References
Quoting the spec : A component element has zero or one implementation element as its child, which points to the implementation used by the component. A component with no implementation element is not runnable, but components of this kind may be useful during a top-down development process as a means of defining the characteristics required of the implementation before the implementation is written. So, in order to be able to deploy and run, your component MUST define it's implementation.

[ANNOUNCE] Apache Tuscany SCA Java 1.2 released
The Apache Tuscany team are delighted to announce the 1.2 release of the Java SCA project. Apache Tuscany provides a runtime environment based on the Service Component Architecture (SCA). SCA is a set of specifications aimed at simplifying SOA application development. These specifications are being standardized by OASIS as part of the Open Composite Services Architecture (Open CSA). The Tuscany SCA Java 1.2 release adds a number of features including: * An improved SCA distributed domain support with an SCA Domain Manager application * Support for running Tuscany in a OSGI runtime using Apache Felix * Support for JAXWS annotations * improved and simplified JMS binding * Improved support for SCA Policies and a new Policy provider SPI * Support for 'native' Groovy component implementation classes * Atom binding now using Apache Abdera * A new Eclipse plugin providing a Tuscany runtime Library and Tuscany launcher in Eclipse environment. For full details about the release and to download the distributions please go to: http://incubator.apache.org/tuscany/sca-java-releases.html To find out more about OASIS Open CSA go to: http://www.oasis-opencsa.org Apache Tuscany welcomes your help. Any contribution, including code, testing, contributions to the documentation, or bug reporting is always appreciated. For more information on how to get involved in Apache Tuscany visit the website at: http://incubator.apache.org/tuscany Thank you for your interest in Apache Tuscany! The Apache Tuscany Team. --- Tuscany is an effort undergoing incubation at the Apache Software Foundation (ASF), sponsored by the Apache 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.
What's next for SCA BPEL Integration
Now that we are making more progress with the SCA BPEL integration and have figured out how to make References to work, let's discuss what could be the next steps on this area. Below are couple examples of what we could do next - WS-BPEL Process Introspection : Currently we are requiring SCA componentType files, we could introspect the BPEL process file to generate the component type information from it. - Integrate BEPL with the store scenario tutorial : We could add a OrderProcessing step to the store checkout, and illustrate a more real integration scenario. Other then these, we could review the SCA_ClientAndImplementationModelFor BPEL and identify other areas that we might need enhancements. Scenarios / Samples / Demos are always welcome too. Or if you have other suggestions, feel free to jump to the discussion.

[GSoC] Accepted Student Proposals for 2008 Announced
It's now official, Google has announced the accepted student proposals for 2008 [1] and the ASF accepted proposals is also available [2].It's very good to see that all the effort done by the Tuscany Community has now materialized as 6 excellent proposals accepted. I'd also want to take this opportunity to welcome the new students to the community, and of course, thanks for all the Tuscany Community that steeped up as mentors and are going to be helping these students trough out the summer and hopefully for a much bigger period of time.

that from the 1.1 distribution and see if everything works for you ?
If yes, then there might be some issues with the project you are

This experimentation especially involves already existing and deployed business web services. I have read various documents on SCA and in particular the very nice article Introducing SCA by David Chappell Associates. Reading this paper - in particular, the section putting together: illustrating an SCA application and the corresponding figure - I was convinced that it was possible to use binding.ws to connect from a SCA domain to a non-SCA web service as well as from a SCA domain to a web service in another SCA domain - say invoke an external non-SCA web service or an extra-SCAdomain web service. However, after installing and experiencing with tuscany-sca-1.1-incubating I did not succeeded once on invoking an external SOAP (asmx) web service, whatever I use binding.ws uri= ... or binding.ws wsdlElement etc.. Depending on the description of binding.ws in the composite file, I get a different execution exception (service not found in WSDL, reflect.UndeclaredThrowableException, ClassCast Exception ...) Moreover, I do not see any corresponding examples in Tuscany Java. So my question is : does this work in Tuscany SCA Java 1.1 ? If the answer is yes, would you please provide me with an corresponding working example (because in that case, I obvioulsy have made a mistake somewhere in the code or composite description )?

As I said in my original proposal, I was expecting community members to have interest in keep maintaining and adding small enhancements to the 1.x branch, we have many users consuming releases from that branch, that might need bug fixes, etc. ant also makes an interesting point about timing. Without clear goals and objectives for Version 2.x, perhaps we should hold off on branching. We have spent a good amount of time to make sure the 1.2 branch is very clean, and working perfectly for the release. With this said, I think it should be considered to be the source for 1.x branch, and we should consider cutting the branch at the moment we have 1.2 out of the door.

Re: Running Tuscany/SCA in Google Android mobile platform
I'd probably categorize the experiment we are doing now, as a learning experience to familiarize with the Mobile environment available in Google Android. For this, we have choosen to try running one of the simplest samples we had (calculator) in the Android JVM environment In the long run, the idea is to have a more light-weight sca mobile core/runtime available, similar to what we did for Web 2.0 (implementation-widget) and described by Mike below. But it's indeed good to discuss these items with the community, would be also good to have the community contributing requirements/scenarios for a Tuscany mobile story. And we are all open and welcoming any help.

But you think that SCA is too heavyweight? Is that simply a question of the size of the code involved (I note that the core of Tuscany is quite small) or is the SCA approach too heavyweight in some other sense? I wonder if you've taken a look a the implementation.widget exemplified in the Tutorial demo code? This applies SCA principles to AJAX widgets running in the browser - simplifying the connectivity a great deal (in my opinion) and yet adding little overhead. In the longer run, we may want to look to do something similar for the Android platforms, perhaps with Java rather than the more limited JavaScript components. Starting with the current SCA package seems reasonable to me - once we have experience with how that works, we will have a better idea what needs to be changed and tailored for the Android platform.

So, when I said branch, I probably should have said a sandbox. I think
we could start with a host-android module where I'd like to experiment
with changing the way we dynamically find extensions and see how
further we can go on executing calculator in the Android environment.
Thoughts ?

What we should copy to this branch? SCA modules and calculator sample? I
think it's enough to start experiment SCA on Android
I sent a msg to Android Developers list, lets wait for the response : )

Good summary Adriano, I haven't had success yet trying to run
Calculator sample application on the Android environment. Below are
some issues I noted
- Looks like our calculator sample dependency has grown out of
control, and is now requiring node, databinding, axiom, etc
- The service locator pattern we use for our extension mechanism is
not working correct in Android environment causing various NPE
- etc
What do you think if create a branch to experiment and try to work on
these issues together ?

Hi,
Luciano and me have been trying to run the SCA calculator sample on the
Google Android platform, that is a platform for mobile devices. As the
Android platform apps are written in Java language, we tried to run the
Java
SCA calculator sample on it.
Although the apps for Android are coded in Java, it's only coded in
Java
language. When it's compiled, it generates not .class files, but a file
called .dex, that is equivalent to .jar files. The .dex files are not
compound of Java standard bytecode, but a special bytecode that is
intended
to run only on Android VM: Dalvik.
So, in our first try to compile the calculator sample, only importing
the
needed SCA jars were not successful, because the SCA jars are compiled
using
JDK compiler and do not have the Android special bytecode format.
Fortunately, when you import the SCA jars into an eclipse Android
project,
it automatically tries to convert the JDK bytecode to Android bytecode
before execute it. But something was not going correctly yet, cause
when it
tries to execute the service I get this exception:
Application Error: com.android.hello An error in com.android.hello.
Unnable
to start activity
ComponentInfo{com.android.hello/com.android.hello.HelloAndroid]:
org.osoa.sca.ServiceRuntimeException: java.lang.NullPointerException.
I wasn't sure about what was happening, and then I tried another
approach:
not import the SCA jars, but place the SCA source code needed by the
calculator sample into the Android app src folder. This way the SCA
would be
compiled directly to Android bytecode.
Unfortunately, the Android is not Java and does not have the entire set
of
classes that J2SE provides. It provides only some java classes as
java.langand
java.util classes which Android developers kept with the same
package/class
names and method signature for easy portability of Java app codes. So,
the
common Java classes used on Java SCA were compatible. But, the Java SCA
uses
a lot the javax.xml package and Android implements only part of this
package
on its platform, so I was getting a lot of errors because the missing
classes that should be contained in this package. I solved it
downloading
the StAX source code and JDK javax.xml API source code, and placing it
directly on my Android app project. Finally I got it compiled.
Then, I got another error. I found out that the Android compiler fist
compile the Java code to .class files and then compile the .class files
to a
.dex file. The first process everything goes fine, meaning the package
dependencies and code syntax are OK. But on the second process, when it
tries convert the .class files to .dex, I get 4 warnings and 1 error
that
are lightly described:

[1] http://code.google.com/soc/2008/ [2] http://wiki.apache.org/general/SummerOfCode2008 Here are a few ideas: A) Simplify the development of Map/Reduce applications and their integration with various sources of information. Integrate Apache Tuscany and Apache Hadoop to allow developers to develop Mappers/Reducers/Combiners as SCA (Service Component Architecture) components, and make it really easy to assemble them together using SCA compositions and integrate external sources of info using the SCA bindings supported by Tuscany (e.g. Web services, JMS and JEE apps, Atom feeds). B) Integrate Google services in SCA compositions. Add a GData binding to Apache Tuscany (could be an extension of the current Tuscany ATOM binding) to allow people to integrate SCA compositions with Google services and GData clients. C) Use Tuscany and Apache Shindig to mash-up Google gadgets and backend SCA service components (Web Services, existing JEE services etc). That GSoC project could explore a few interesting options, including: - Use SCA to model references from Javascript gadgets to server-side services, and provide transparent access to these services (by injecting Javascript proxies into the gadgets, similar to what Tuscany currently does with its SCA Widget component support). - Use SCA composites to configure and assemble the gadgets together as well, allowing the application developer to use a consistent SCA-based assembly model for client-side mashups, server-side compositions and mixes of the two. I may propose one or two more ideas in a day or two, after I think about them a bit more over the weekend :) -- Jean-Sebastien - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED] -- Luciano Resende Apache Tuscany Committer http://people.apache.org/~lresende http://lresende.blogspot.com/ - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]

Re: [Cross Subproject Discussion] options for SDO Java in Apache
Our current DAS implementation only has support for SDO types, and most of our users, if not all, are SDO users that need support for Relation Database stores. Based on this, I think this discussion should also consider having DAS together with SDO, either in Tuscany or in a different SDO TLP Incubator project. On Fri, Feb 15, 2008 at 2:39 AM, Mike Edwards [EMAIL PROTECTED] wrote: Folks, A few observations inline. Ron Gavlin wrote: I think consolidating the two SDO implementations under a single implementation would be good for the entire Apache SDO community. My concern would be that no Tuscany SDO features be lost in the transition. The new implementation should provide most of what I can currently achieve using both EMF and Tuscany SDO. For example, EMF features like integrated validation should be available in the new implementation before the old implementation is dumped. It might be a good idea to poll the Tuscany SDO community to identify the EMF features currently being used by Tuscany SDO community. It might also be interesting to poll the Eclipse EMF SDO 1.0 community and ask the same question. Maybe many of the existing Tuscany SDO test cases could be re-written for either 1). the new implementation or 2). the CTS, to minimize the loss of functionality during the transition. There is a fundamental tension here which I think it is important to recognise. On the one hand, we want to ensure a lively and progressive Apache SDO community that continually extends the capabilities of SDO to better suit the needs of users. Innovation is a bit part of this story. On the other hand, we're trying to promote an open (and open source) approach to the standardization of the SDO interfaces, to help ensure consistent implementation of SDO across products both commercial and open source. There is a JSR and a set of activities taking place in OASIS for this. Part of that work is to produce an RI and a TCK, open to all. However, an RI must be just that - an exemplary implementation of the specification, the whole specification and nothing but the specification. Similarly, the TCK must be testing compliance of implementations with the specification, the whole specification and nothing beyond the specification. This demands limitations on innovation. So, there is some careful work required in building both forward-looking innovative capabilities and at the same time creating somewhat rigid RIs and TCKs, which are inevitably tied to specific versions of a specification. I think that the proposal to have a second SDO project in Apache is regarded as one way to approach these conflicting requirements. It may not be the only way, but at least it would provide clear dividing lines that both contributors and users can understand easily. It will take some careful thought to combine these aspects within one project in a way that works for all contributors and for all users. One of the reasons that Tuscany is NOT an RI and does NOT contain a TCK for SCA is because it fosters freedom in the implementation of new capabilities that go well beyond the current SCA specifications. Some of these will feed into future standard specifications, I'm sure. From my perspective, the priorities for Apache SDO moving forward should be: 1. Align Apache SDO with the JAXB specification. The static SDO implementation should be JAXB-compliant. 2. Align Apache SDO with the JPA specification. It should be simple to use a OpenJPA to persist SDO graphs. 3. Provide data binding support for popular Java open source WS stacks, especially Axis2 and CXF. Yes, all good innovative stuff. I could toss in a few more, such as having an SDO implementation for JavaScript to address AJAX applications. But how to square this with the RI and TCK with fixed functions matching the SDO 2.1 specification? - Ron Yours, Mike. - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED] -- Luciano Resende Apache Tuscany Committer http://people.apache.org/~lresende http://lresende.blogspot.com/ - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]

This is something I have started and I'm planning to finalize in the near future. Any help is appreciated, either on the implementation or with some sample scenarios.

At least, I did not find examples or documentation about this and in ODEMessageExchangeContext.java there is no code yet to invoke other components as partners, and this is the place where I would have expected something like this. Are there plans to add this in the near future? What will be possible then? Or did I just miss something (maybe even an examples?).

Re: SDO and Spring
Tim, as Kelvin mentioned, DAS would be the component handling heterogeneous data sources, it would be the interface between the Data (SDO Graphs) and the Data repository. From your e-mail, it looks like you want to persist the SDO utilizing Hibernate or Spring DAO. I could see two ways here : Having a new DAS implementation that would utilize this technology to persist the data (but note that Apache have license issues with Hibernate) or refactory DAS to allow plugability of the persistent layer (today RDB DAS uses JDBC under the covers to persist the data to RDB). Could you also elaborate little more on your cache question ? On Dec 13, 2007 1:39 AM, kelvin goodson [EMAIL PROTECTED] wrote: Hi Tim, welcome to Tuscany. What I'm not completely clear on from your question is what you mean by publish and central graph. There's a related discussion on this list going on (see [1]), and its clear that Jason too had initial difficulty seeing the picture here until he found the DAS material. I think perhaps we need to do some work on the SDO part of the Tuscany website to make this better understood. Bert Robben has taken part in that discussion, and his scenario involves SDO as the primary data API, with conversion to other data formats via an abstract black box snapshot format being done when necessary, such as Hibernate being used for some of the back end persistence activity. So the notion behind the SDO API design is that in order to access heterogeneous data sources, Data Access Services will be created to build SDO data graphs. The RDB DAS is one such example, and you can view the XMLHelper as providing the services of another. If you are using an RDB as your central store and want SDO access to the data then the natural solution is to use the RDB DAS. Tuscany has no concept of providing a façade over other data handling implementations, and I think the disparity in the features of the data representations you mention would mean that providing an SDO façade would not be the natural way of solving interoperability. I'd be keen to get a better idea of your scenario in order to be able to understand in more detail how SDO can help you. Regards, Kelvin.

SCA in Web 2.0 applications...
I have created a new implementation type (implementation.widget) that starts to extend the SCA programming model to web 2.0 client applications. This is similar to what was proposed on this thread [1], we can now turn a html into a SCA component, declare references using JavaScript, and get them wired using SCA. Considering the store composite [1], component name=store tuscany:implementation.widget location=content/store.html/ service name=Widget tuscany:binding.http/ /service reference name=Catalog target=Catalog tuscany:binding.jsonrpc/ /reference reference name=ShoppingCart target=ShoppingCart tuscany:binding.atom uri=/ShoppingCart/ /reference /component component name=Catalog implementation.java class=store.CatalogImpl/ service name=Catalog tuscany:binding.jsonrpc uri=/Catalog/ /service /component component name=ShoppingCart implementation.java class=store.ShoppingCartImpl/ service name=Collection tuscany:binding.atom/ /service /component Declaring SCA references using JavaScript can be done with the syntax below. This references will get properly introspected by the implementation.widget and wired. //@Reference var catalog = new Reference(Catalog); //@Reference var shoppingCart = new Reference(ShoppingCart); The client application would need to include a generated js, that has the same name as the component being used. !-- one js include per sca component -- script type=text/javascript src=store.js/script Right now there is support for JSONRPC and Atom, and you can see all of this in in action in sca/samples/store. Please, provide your feedback, and let me know if you have more scenarios that would enhance and simplify the programming model in a web 2.0 application scenario.

Re: [DISCUSS] Tuscany SCA Roadmap and next releases
From what you mentioned, I'm very interested in the web 2.0 integration, and the ability to mashup SCA components/services using simple SCA References concept on a web 2.0 client application. I think that we should also add Data Integration to our Roadmap, as I see SCA of great help to simplify exposing data as services to a client application in a simple and flexible way. As for Core capabilities, I think we should improve the error reporting/handling for our data binding framework.

So it's probably the right time now to ask what people want to do next and try to build a roadmap for the next few releases. Here are a few random thoughts to initiate the discussion. I've just listed the things that came to my mind this morning, but I'm sure that there's much much more to add :) - Support for transaction and reliability policies Several users have asked for it, and there's now a public draft of the transaction policy spec - Webapp and EJB module integration I'd like to track the OASIS work on this and implement it in parallel in Tuscany. Many users have existing J2EE EJB and EAR modules that they'll need to integrate in bigger SCA compositions. Also Webapp developers will need a non-intrusive way to wire a Webapp with other SCA components in an SCA domain. - Conversational and non blocking + callback programming model over Web2.0 bindings Seems like a good fit with JSON for example... in particular Ajax interactions fit really well with the SCA non blocking + callback programming model. - Ability to model client side JavaScript components Looking at the Store sample for example, I'd like to be able to model the client Javascript as a component with SCA references to the ShoppingCart and Catalog services, instead of manually creating JSON and Atom client proxies in the client Javascript code. - Support for Atom using Apache Abdera Abdera just released their 0.3.0, I've started to look at it and it looks pretty good. I think we should try to port our Atom/RSS binding to it and see how it compares with the Rome library which we are currently using. - More modular distributions, in addition to our current all-in-one distribution, distribute smaller packages that people can choose to install or not? - Some clean up of the core runtime invocation and injection mechanism, we can probably simplify and actually remove code in a number of places :) Could people please jump in and say what they want to see in the next few releases?

[ANNOUNCE] Apache Tuscany Java DAS 1.0-incubating-beta2 released
October 06st 2007 - Apache Tuscany is pleased to announce the 1.0-incubating-beta2 release of the Java DAS project. Data Access Services (DAS) works together with Service Data Objects (SDO) simplifying handling of data when interacting with the back-end data source and frees application developers from dealing with tedious and error-prone transformation between end source types and SDO Data Object Types/properties. The main purpose of the DAS beta2 release is to fix incompatibilities that were found with SDO 1.0 release. For a complete list of changes on this release, please view the release notes. https://svn.apache.org/repos/asf/incubator/tuscany/tags/java/das/1.0-incubating-beta2/distribution/binary/RELEASE_NOTES To download Java DAS please follow the link to http://incubator.apache.org/tuscany/das-java-releases.html Apache Tuscany welcomes your help. Any contribution, including code, testing, improving the documentation, or bug reporting is always appreciated. For more information on how to get involved in Apache Tuscany visit the website at: http://incubator.apache.org/tuscany. Thank you for your interest in Apache Tuscany! The Apache Tuscany Team. --- Tuscany is an effort undergoing incubation at the Apache Software Foundation (ASF), sponsored by the Apache 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. -- Luciano Resende Apache Tuscany Committer http://people.apache.org/~lresende http://lresende.blogspot.com/ - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]

Re: [DAS] Transaction support - a bigger picture question
Hey, very good, some comments inline One question that I have is regarding the Transaction Manager, who is responsible for creating the transaction manager ? The SCA runtime, or implementations ? In the case of SCA runtime, we need to investigate that part, but I guess we can start by having it under the implementation as a proof of concept for now.

I'll leave comments on the policy side to Venkat or Sebastien or others that have been playing on this area... And logic to support this method 2) ConnectionInfo new attribute managedtx with setter/getter Ok B tuscany-implementation-das 1) DASImplementation implements PolicyAttachPoint 2) DASImplementationProcessor read(reader) - will read policies and intents on DASImplementation from .composite Who should read here, implementation.das or we should delegate to the policy artifact processors ? 3) DASImplementationProvider createInvoker() will call getDAS(passing config, connectioninfo, intents, policies) same will be for createCallbackInvoker() What other information you will need from intents and policies when creating DAS ? you already passed the managed transaction flag inside the connectionInfo, right ? Note that there is still support for a das config file, how are you going to manage that ? We probably need to throw an exception if DAS config file sets does NOT set the managed transaction flag, but transaction policy is set. With these above changes and with setup similar to JIRA-1665 sample, I could see that the external connection is being used by DAS (naming service is resolving datasource properly). The point I am stuck at is, in RDB-DAS, when we use external DS, we do not pass userName, password. But MYSQL (which with InnoDB supports Txn and works well with JOTM) does need id, pwd in ds.getConnection(). This can be case with other DBs as well. So, it looks like DAS config.xsd needs to allow passing userName, password in ConnectionInfo too ( and not just for ConnectionProperties). Thus below will be the changed DAS config portion:- xsd:complexType name=ConnectionInfo xsd:sequence xsd:element maxOccurs=1 minOccurs=0 name=ConnectionProperties type=config:ConnectionProperties/ /xsd:sequence xsd:attribute name=dataSource type=xsd:string/ xsd:attribute name=managedtx type=xsd:boolean default=true/ xsd:attribute name=userName type=xsd:string default=/ xsd:attribute name=password type=xsd:string default=/ /xsd:complexType xsd:complexType name=ConnectionProperties xsd:attribute name=driverClass type=xsd:string/ xsd:attribute name=databaseURL type=xsd:string/ xsd:attribute name=loginTimeout type=xsd:int default=0/ /xsd:complexType Create a DAS jira for this, and we can investigate further... Suggestion? If this looks OK, I would like to make the above changes and create a sample in tuscany-implementation-das demoing use of intent and ext TM. I have a demo in progress, probably is good to have a test case for now, and we could incorporate transaction support on the demo. Will give a try with geronimo as well.

Re: Help with Tuscany Customer's Demo using MySQL
Hey Eric
I had it working in my environment yesterday, and I thought you had
it too after the changes on the connection info. In my case, I have a
dastest user in mySQL, I created the empty database in mySQL and
granted all the permissions to the dastest user. After that the
customer sample worked fine. Maybe you could check if the mySQL table
was created properly, and I can check further in my env. BTW the only
issue you are having now is the
exception below ?

Subject: RE: Help with Tuscany Customer's Demo using MySQL
I've had little luck with my remaining problem, however, any idea what
java.lang.IllegalArgumentException: Class 'CUSTOMER' does not have a
feature named 'ID' means I've done?
It's creating the database, but perhaps never correctly constructing
the
data graph?
If you notice, the program output is supposed to display the four
lines
of db entries after each operation (as it does using derby), but with
mysql, none. :(
I was reading about oracle and das this morning:
https://issues.apache.org/jira/browse/TUSCANY-1355
Is this problem applicable? I may tinker with those ideas in the
meantime. Plz help, seems like it would be a common issue when
dealing
with mysql. Especially since it's the most basic of the demos!

Good, looks like we have most (if not all) the updates necessary to support SDO 2.1 specification and to be compatible with SDO 1.0 release.

As for our history with SCA integration, we have started efforts around Data Services/Declarative DAS (implementation.das) and Data Feeds (implementation.data), and this is probably another area we would like to continue to work going forward. I also think we should continue to improve our user documentation and distribution infrastructure to make our release cut easier. Below is a summary list of items and JIRAs that are related to these possible items : - TUSCANY-986 - DAS integration with SDO 2.1 APIs - TUSCANY-961 - DAS: Using deprected SDO method causes Type lookup failure - Refactoring DAS to allow multiple implementatons As for timeframe, maybe it would be good to have a release in the next couple weeks, to support SDO 1.0 and be available to the SCA release, so we can have the integration story with SCA available. This is just of brain dump of where my thinking is at the moment, I'm sure everyone has their own thoughts about things we should tackle.

[ANNOUNCE] Apache Tuscany Java DAS 1.0-incubating-beta1 released
August 21st 2007 - Apache Tuscany is pleased to announce the 1.0-incubating-beta1 release of the Java DAS project. Data Access Services (DAS) works together with Service Data Objects (SDO) simplifying handling of data when interacting with the back-end data source and frees application developers from dealing with tedious and error-prone transformation between end source types and SDO Data Object Types/properties. Key features of 1.0-incubating-beta1 release are : - Support for J2SE connections in DAS config using Driver Manager. - Added support for multiple database schemas in queries - Enhanced Optimistic Concurrency Control with overqualified updates - Multiple enhancements around ApplyChanges API - Enhanced Documentation : User, Developer and Architect guides as well as javadocs - Enhanced and new sample applications For a complete list of changes on this release, please view the release notes. https://svn.apache.org/repos/asf/incubator/tuscany/tags/java/das/1.0-incubating-beta1/distribution/binary/RELEASE_NOTES To download Java DAS please follow the link to http://incubator.apache.org/tuscany/das-downloads.html Apache Tuscany welcomes your help. Any contribution, including code, testing, improving the documentation, or bug reporting is always appreciated. For more information on how to get involved in Apache Tuscany visit the website at: http://incubator.apache.org/tuscany. Thank you for your interest in Apache Tuscany! The Apache Tuscany Team. --- Tuscany is an effort undergoing incubation at the Apache Software Foundation (ASF), sponsored by the Apache 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. -- Luciano Resende Apache Tuscany Committer http://people.apache.org/~lresende http://lresende.blogspot.com/ - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
[DAS] What's next for Tuscany DAS ?
With the DAS beta1 release out, I'd like to look forward to things that we want to do next for DAS. I think that there are still couple things that we can improve our core DAS features, the main one would be adding support for multiple DAS implementations, and review our SDO 2.1 APIs usage. As for our history with SCA integration, we have started efforts around Data Services/Declarative DAS (implementation.das) and Data Feeds (implementation.data), and this is probably another area we would like to continue to work going forward. I also think we should continue to improve our user documentation and distribution infrastructure to make our release cut easier. Below is a summary list of items and JIRAs that are related to these possible items : - TUSCANY-986 - DAS integration with SDO 2.1 APIs - TUSCANY-961 - DAS: Using deprected SDO method causes Type lookup failure - Refactoring DAS to allow multiple implementatons As for timeframe, maybe it would be good to have a release in the next couple weeks, to support SDO 1.0 and be available to the SCA release, so we can have the integration story with SCA available. This is just of brain dump of where my thinking is at the moment, I'm sure everyone has their own thoughts about things we should tackle. It would be good to get to them all on the table :-) Thoughts ? -- Luciano Resende Apache Tuscany Committer http://people.apache.org/~lresende http://lresende.blogspot.com/ - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]

This way, the responsibility of transaction management can be taken by user for 4)(as it is today) and 2)(as now user will get handle) For 1) and 3) - TRANSACTION_DEMARCATION_PER_COMMAND=true is already working in RDB DAS today. For handling TRANSACTION_DEMARCATION_PER_COMMAND=false, new APIs can be given to user like DAS.getTransaction().commit() /rollback() , so in a controlled way, user will be able to bunch group of Commands based on business logic and issue commits/rollbacks.

When false, external caller is responsible for managing transaction. There is no way to bunch a set of Commands in one transaction under control of DAS, it is at the mercy of external caller (when managedtx is false).

b what is the reason behind providing case 1)? when client/container
provides connection, it can be controlled by client/container. and even if
DAS tries to controll it, as user has handle to connection,
commits/rollbacks can be issued by client async with what DAS is trying to
control. So there will be no meaning in DAS controlling the connection
supplied by client. And so there is no meaning to managedtx either.
c case 2), as of today there is no way to expose connection to client when
it is created by DAS. so neither DAS nor client manages transaction. For
this case exposing connection thru getConnection() will be useful (for other
cases, it can be banned)
In the case where client code requires access to the connection, is
there any issue with supplying it to DAS ?
d as DAS is heterogeneous API, is the DAS config going to be
heterogeneous too? If yes, then it will be advantageousto support the
transactional nature of RDB using such semantics. If the backend (non RDB)
does not support transaction, this semantics will be of no use, but
in this case the DAS config can be different (more tuned to that particular
backend)
So, it all depends on whether we are following the path to support DAS with
heterogeneous APIs or not. Will you please elaborate meaning of
heterogeneous API in context of different flavors of DAS?
Yes, the idea is that each impl would define it's own model,
inheriting from a common root class (xsd element)
e {If you already defined the transaction demarcation flags...}Where are we
doing that at present? What is there is only issue commit/rollback at the
end of each DAS Command. Am I missing some other transaction demarcation
mechanism already available in DAS?

Also, couple questions :
