Re: ** IMPLEMENTATION.BPEL USERS ** - updated implementation-bpel code in trunk - affects your BPEL applications
I am cc'ing tunscay-users since this seems to be interesting to users and they may not be on the dev list. Thanks Mike. On 5/17/08, Mike Edwards [EMAIL PROTECTED] wrote: Folks, I've just committed some changes to the implementation-bpel and implementatio-bpel-ode code in trunk which fix some issues relating to exposing BPEL processes using Web services (and other remote protocols). These changes have an impact on the content of the deploy.xml file that is associated with your BPEL applications. In order to work correctly, you will need to ensure that your deploy.xml file corresponds to the following pattern: deploy xmlns=http://www.apache.org/ode/schemas/dd/2007/03; xmlns:tns=http://helloworld; xmlns:helloworld=http://helloworld; xmlns:greetings=http://greetings; xmlns:tus=http://tuscany.apache.org; process name=tns:HelloWorld activetrue/active provide partnerLink=helloPartnerLink service name=tus:helloPartnerLink port=HelloWorld/ /provide invoke partnerLink=greetingsPartnerLink service name=tus:greetingsPartnerLink port=Greetings/ /invoke /process /deploy You must ensure: a) Each partner link in your BPEL process is declared using either a provide.../ (for a service) or using a invoke.../ for a reference. b) Each provide/ and invoke/ must use the partnerLink name, as declared in your BPEL process. c) The provide/ and invoke/ elements each have a single child service/ element. The service/ elements have name and port attributes. The NAME attribute MUST be set to the same name as the partnerLink and MUST be prefixed by a prefix which references the namespace http://tuscany.apache.org; (tus in the example above). The port attribute can be set to any name (it must be present but it is not actually used for anything significant). Sorry for forcing this change on you all, but the previous version of the code had a mixup over the name of the services and references as used by the ODE BPEL engine - this change fixes that problem. In the next week, we shall aim to remove the need for the deploy.xml file entirely. All the information in the file is already known to the Tuscany code - either we shall generate the file dynamically, or - ODE willing - we shall pass the information to ODE in-memory, avoiding the need for a file at all. You will find that the BPEL Sample applications and the BPEL iTests have been adjusted to use this new format for the deploy.xml file. Yours, Mike.

These services are built on top of the Tuscany runtime and allow Amdocs customers to integrate their existing systems with Cramer6 OSS Suite services using whatever technology is appropriate.

Re: STP SCA Component - STP SCA Tools sub project
Hi Stephan, This looks good since it looks like tools for SCA will get more focus :) I have a question. You mention the goals of the new sub-project are to develop a set of tools for SCA developers and SCA users. What is the difference between SCA developer and SCA user in this context? Haleh On 4/2/08, Stéphane Drapeau [EMAIL PROTECTED] wrote: Hi Jean-Sebastien, Haleh, all, The proposal is a 3 pages document describing the scope/intent of the proposed project. The outline is: 1. Introduction: the proposition of the transformation of the STP/SCA component into a sub-project named SCA Tools under the top level project STP. 2. Background: presentation of STP + presentation of the existing STP/SCA component. 3. Description: the goals of the new sub-project are to develop a set of tools for SCA developers and SCA users. Another goal is also to link this sub-project with other components of STP (Service Creation, Policy Editor) 4. Proposed components: SCA Domain Model (SCA meta model), SCA Composite Designer, SCA Composite Editors (tree, xml and form), SCA Integration (integration with other STP components) 5. Relationship with Other Eclipse Projects: STP, EMF, GMF, M2M, ... 6. Organization: this sub-project will take place under the top level project STP. 7. A list of proposed initial committers. 8. Code Contribution: the Eclipse STP/SCA component will be the initial code. 9. Interested parties: this section lists companies and communities that support the creation of the project. They don't take other engagements. 10. Tentative Plan for 2008 and 2009. Our goal is to identify formally the scope of the tools that we develop around SCA. The new status will provide some advantages. - I think that the SCA tools will be more visible in the Eclipse community if we are identified as a sub-project. - From the users point of view, it will not change anything. - Concerning us, we should be more formal: clear roadmap, new features described/discussed first in bugzilla, ... - It will also present some advantages for Obeo by becoming a sub-project leader. In the near future all STP components will become STP sub-projects. To summarize, all of this is purely administrative. I will send you the proposal document ASAP. If you have any questions, don't hesitate. Haleh, yesterday I sent you more information about the SCA Composite Designer on the thread named [Website] - Tooling for Java SCA. You can add it on the web page. Tell me if you need more/different information. My post describes what version of Tuscany can be used. I also introduce a tutorial that I made.

Getting a high-level understanding of what kinds and solutions are trying to be solved with Tuscany would be great also. Providing this kind of information IMHO would really help to give a sense of how people are envisioning the use of Tuscany and how/when people are considering Tuscany to be used as a product that is ready for prime time use, like spring, and other ubiquitous open-source products. As an example of the kind of information that I think would be beneficial to many on the list I will go first. Currently working for a consulting firm with a major financial services Institute in Canada to implement a mix of retail and commercial banking services. We plan to go into production by the end of this quarter, we have finished the majority of implementation, conducted functional and performance testing (with very good results) and plan to do a limited deployment with a small subset of users within a couple of months. We are currently deploying Tuscany on websphere 6.1, Solaris 10, and taking advantage of a combination of Web services bindings/SDO as well as local/spring bindings. An interesting wrinkle is that we are also basing all of our service interfaces on the IFX banking standard, which breaks SDO in a couple of places.

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.

Hi, We already have a news section on the home page which repeats most of what is on the event page. The information on the event page seems to be old and not being updated. How about a) remove the events link from the community box b) add a new link to the community box called 'projects using tuscany' . This can be updated by users who would like to share information.

Re: Client requested features Was: Policy samples? (showcasing the killer feature of separation of concerns)
Jeff, Thank you for your valuable feedback. With the work going on for release .99 and release 1.0 this email might not have been noticed. I have created JIRAs 1666 through 1669 for your requested features. I will also add the JIRAs to release discussion page for 1.0 [1], although some of these seem to be longer term enhancements. Any contribution is welcomed. on BPEL integration with Tuscany: Apache Ode team started BPEL integration with Tuscany and an initial version was checked into svn[2]. More needs to be done though.

An FYI to everyone on the list... I'm currently working with a major Canadian FSI client to develop a SOA platform based largely on Tuscany 9.1. Services are currently being developed and tested for the platform, with plans to go into production by the end of this year. I've just finished holding a architecture workshop where we discussed the benefits of our platform (largely based on Tuscany) to various technical stakeholders across the greater organization. Representative stakeholders were given the chance to prioritize what they consider to be the most important features that they would want to see in the platform. I have decided to share this with this list, as I believe that the majority of most of these requirements could be handled through a future version of Tuscany. Currently the biggest feature requested is a service lifecycle mechanism that is capable of supporting both POJO/local method invocation as well as remote WSI basic interoperable mechanisms. Key to this feature would be the ability to transparently switch from a local/POJO to a remote/WSI interoperable model without impacting business service code. Specifically we are looking for Tuscany to allow us to support the following 1) security-would like to be able to specify participation in existing security context much like the mechanisms provided by WS security, WS-secconv, and related specifications. However, current implementations of Web services stacks makes it difficult to evolve a local component to a true web service and back again without having to follow a completely different security model. We believe Tuscany to be a excellent location to access a policy driven framework that allow us to specify security requirements of the service either using annotations, SCDL configuration, or some other method. Soap headers, or local security context could interact with the security policy dependent on each of the SCA binding used to wire together the various services. Some examples could be the use of a @Fedactive annotation to declare that a services capable of issuing messages containing security tokens such as those described by WS-security and WS-trust. Within a local binding, the annotation could still declare a need for the service to issue explicit security tokens, although the token may be passed using a different mechanism. It would be ideal to have this model follow a more framework approach, with the explicitly defined plug-in architecture allowing third-party vendors to integrate Tuscany to their own vendor suite. 2) transaction/compensation-I realize that the SCA specification is little more vague/not finalized concerning this, however this is one of the most important features requested from our client. Again I envision using the policy framework to define a transaction setting such as @NotRequired,@Supported etc. For local bindings this would simply allow the typical distributed transaction mechanisms to reverse any resources held within a transaction lock. For a more traditional remote Web services environment where resource control is the exception rather than the rule, an additional annotation of @compensator would allow service developer to declare the compensation transaction required whenever the appropriate binding container declares that a part of the transaction has failed. Again I believe the mechanisms of the model would vary depending on the binding mechanism used. For remote , WSI-Basic interoperable services can use WS -- atomic. For local, services would have the option of leveraging the the compensation model or integrate into the existing container distributed transaction manager. I realize that people In Tuscany are hesitant to start working on this kind of work until the spec has more details around transactions. However I believe the majority of this implementation could go forward
Re: Is there value in keeping download links for old releases?
I'd like to bring this message back to life. A few users posted to the ML recently and asked about M2. Immediate response has been to use the latest since M2 is very old (IMHO makes sense). This email thread was suggesting to remove the download link of very old releases to avoid confusion. We can leave the release history in place to show that there was a release, but remove the link for download to avoid confusion. If everyone agrees, when does a link get removed, in other words, how old the release should be? For starter, M2 is based on an older version of the spec. Should we remove the download link?

Does it make sense to have the latest release and the previous release as an option for download and leave everything else under history or remove them? Haleh I think yes we should keep them. One of the first things I look at when coming across an open source project is the release history as it gives you a good indication of how much life there is in the project. Maybe from that we don't need actual links to the download artifacts, but something clearly showing we do regular releases and have been doing so for years is a Good Thing IMHO. Another reason is if someone is debugging some old system with a back level release they may need access to the source distro to debug the code. ...ant
sample news page....
Hi, Here is a sample of SCA news page that I had proposed last week[1]. This news page includes information about both Java SCA and Native SCA. It is a live page that reflects what's going on in the project (no old news). This page is created on TuscanyWiki so that everyone can add information to it. It currently has two main sections. Project news and user news. Please feel free to add more if you can think of other news categories to add. Please help keep this page interesting! Share what you think is useful. If your news script consists of long text, please provide a link to a page to keep this page easy to read. I'll go ahead and link it to the website for now at [2]. Let's give this a few weeks to see how it evolves. Do you think we should have one Tuscany news page or separate ones for SCA, SDO and DAS?

Re: SDO Java 1.0-incubating release candidate 1
Hi Kelvin, 1. As Ant pointed out, Release note needs to be updated to capture the very important announcement that was made for SDO Tuscany and that is completion of SDO spec 2.1. 2. Tuscany 1143 was identified as an unresolved defect for Beta. Should this be addressed in 1.0 or can it be moved to post 1.0? 3. some of the links on this page do not work: C:\sdoRel1\tuscany- sdo-1.0-incubating\docs\javadoc\sdo-samples\index.html 4. Is commentary_for_x the level of trace? If yes, would it make sense to change the name to trace_detailed, trace_medium, trace_low? 5. C:\sdoRel1\tuscany- sdo-1.0-incubating\docs\javadoc\sdo-samples\index.html.. javadoc for Class SampleBase. Are these SPIs that one would use to develop samples? If yes, the text reads as if this and the sampleInfra are not interesting to users. 6. Samples Overview: a) In the overview parag you have a link to Tuscany main site for the section you say contribute pack to the project. It would be better if this linked to getInvolved page. b) You could remove the first sentence since it does not really make sense. How about .. Apache Tuscany SDO Samples are provided here to help users learn SDO.'index by SDO subproject ' lists the different samples available to you. These samples provide a starting point for learning SDO and can be extended and enhanced to experiment with other available SDO features. Please help us enhance these samples by sending your feedback to Tuscany mailing list or join us and contribute to this project get involved link. 7. Running samples: can you modify the test to make it clear that BINARY-BASE is a variable that needs to be set in the script? For example... In order to run the samples, locate runSamples script file for the environment you work on under samples directory. Modify the file to point BINARY-BASE to the directory on your file system where lib and samples reside. You are then ready to run the samples. btw. I did this and I get an error.

Then the 'getting started with DAS' guide can be focused on explaining what are the key setup pieces in the sample and what the purpose for each step is? Just a thought..

Re: [DAS] Release distributions - PLEASE PROVIDE FEEDBACK
Most users who download binary would want samples. Therefore, they will end up with the same size of package at the end of the road anyway.

Re: Website - Feedback please
Kelvin, Thanks for your review. You mentioned that scopes should be the same when on a given page. I agree. I fixed it. We now have a sdo cpp FAQ and a sdo Java FAQ. I also moved text from some of the mentioned threads to the FAQ. The ones I did not is because I did not know how to net it down to a question and an answer. You mentioned General heading can be called Tuscany or SDO General heading. The General heading is more a collection of things that I couldn't find a good title for on that page :) It is not intended to be general for Tuscany. Some suggestion for the SDO Java page: 1) Using SDO Java could move to 'user guide' on this page. 2) Code structure can move to get involved or even to the architecture doc If there is agreement, I go ahead and make the changes. Haleh On 4/12/07, kelvin goodson [EMAIL PROTECTED] wrote: Haleh, thanks for addressing these issues. One concern I have after a quick look is that on arriving at a pages such as http://cwiki.apache.org/TUSCANY/sdo-java.html some of the links on the left under a given heading go off to a scope that is not intuitive from the page that you were on. E.g. under the General sidebar heading, the FAQ link for Java SDO goes to a page that I think is intended to contain generic cross language SDO questions, i.e. up one level of abstraction from the page heading. It's been that way since version 3 of the file, and I can't work out whether it's intended that way, or just a result of copying the content from an existing C++ page. The next sidebar heading below FAQ --- Downloads --- relates to downloading SDO Java (i.e. at the same level of abstraction of the current page). I think it would be good if the sidebar headings grouped links at the same level of abstraction and made this clear from the heading name - e.g. Tuscany General, or SDO General BTW, FWIW, this prompted me to just catalogue the set of tuscany-dev notes that I have put an FAQ label against when reading the list.

As the first step to improving the website, I created a consistent look across all pages and hopefully an easier navigation of content. I have also moved some of the content from one page to another to better organize it (for example, DAS page). I'd like your feedback please. I have encountered a problem that I can't figure out.

Re: Developing an SCA Application: Best Practices
Hi Andy, Very good 'SCA best practices' write-up. I'll add this to the list of user documents on cwiki and like you I am interested to to see if Tuscany users have other 'best practices' hints that they might want to add to this. Thanks. Haleh On 2/13/07, Andrew Borley [EMAIL PROTECTED] wrote: Hi All, After writing the Alert Aggregator sample for the Tuscany Native runtime I thought it would be worthwhile documenting my experiences. I've titled this Best Practices but perhaps Hints Tips or Andy's Observations would be more appropriate! Anyway, below is a suggested list of things to do/think about when writing your own SCA based applications. A few of the points below are from general software development, but they apply equally to SCA development. Start by drawing your SCA diagram (e.g. [1]) - this helps with the componentization of your app. SCA diagrams aren't code path diagrams (such as a BPEL visualization): they simply show what blocks of function you have and which blocks are used by other blocks. Separating components into composites also helps you think about componentization and deployment, as (currently) the smallest deployable block is a composite. Similarly, an SCA diagram is not a class diagram - the smallest SCA unit is the component which could consist of multiple classes or scripts or similar. You may have a requirement for a Utilities class providing some basic function that is used by lots of other classes - SCA wires involve a certain amount of overhead, so it may not be worth creating a Utilities component that all other components reference. Instead, it can be valid to have multiple instances of the same class embedded as part of multiple components. Think about the services and references that your components and composites provide/require, so you can draw the wiring on the diagram and work out which components and composites you need, but don't worry too much about bindings (REST, WS, etc) - SCA/Tuscany makes it so easy to switch bindings that this can be decided at a later time. I didn't worry too much about interfaces at this point - I planned to do most of my components in scripting languages (which don't need defined interfaces in Tuscany Native). In other languages (Java, C++) it may be worth defining the public interfaces that your component implements, so you can see how and where functions are implemented within your composites. When coding the component implementations, it's easiest to start with the 'least-dependent' components - those that don't need lots of other infrastructure or other components or composites in place. For the Alert Aggregator sample (see [1]), my order of component development was as follows: RSSChecker AlertConfig AlertChecker HTMLFormatter POPChecker Of course, as in normal software development, this was an iterative process where each component got revisited as necessary. Component implementations were developed in a standard test-driven manner, but deploying within an SCA runtime adds extra layers of required testing (think unit vs. system tests). I began by testing my component implementations in a standalone, unit-testing-style fashion, then tested under Tuscany via local clients, then via remote clients using whichever service bindings I had chosen and finally via full system tests (in the Alert Aggregator case, through clicking on a web page). The power of SCA meant that I could use the same client code for both local and remote testing , just by adding in a local SCA reference that called the remote service (see the PythonCalculator sample for an example of this - the sample.calculator.client/client.py code is almost exactly the same as the sample.calculator.wsclient/client.py code). I found I needed to programme somewhat defensively - Tuscany SCA Native (or at least the extensions I used) is not yet particularly good at handling exceptions or errors that get thrown, but not caught, in component code. Instead, I tried to check for bad data and catch exception cases within the component implementation. The handling of errors is something that definately needs more work in Tuscany SCA Native - should errors get propagated back to the original client, or should they be caught and logged? A problem that exacerbates this issue is that some of our logging messages don't provide much (or any!) useful information! The XML story with Tuscany SCA Native is pretty good - I found using SDO/XML/Python ElementTree objects easy and very useful. I would probably go as far as suggesting that developers use XML complex types and SDO rather than trying to flow multiple method parameters, as this can mean less changes required in code and interfaces throughout the development cycle. That's about all the issues and observations that are at the top of my head right now - I've put also this up on the wiki at [2] and hope it can become a more rounded and useful document for users of Tuscany to consider. Let me know what you think, I'd be

Global Alerter A feed-reader style webapp that aggregates various sources of changing data into a series of alerts that are displayed in, and automatically updated via AJAX calls from, a web page. Alert sources include RSS/Atom news feeds, POP3/IMAP email, NNTP newsgroups, SOAP services (such as stockquotes). See the attached png for the initial SCA diagram (I've also put it up at [1] if the mail-list doesn't let png's through) for a bit more detail. This shows some of the power that SCA and Tuscany provides: - the 2 composites could run in separate containers or even different SCA runtimes (say HTTPD/PHP with SCA_SDO for the Display Composite and HTTPD/Tuscany C++ for the Alerter Composite) - we could show extensibility by adding extra Checker components for other data sources (such as a component that checks for changes in a specific web page) - we could show re-use of components by using the Web Service Checker to call a stockquote service and a weather forecast service. - we can use different languages to implement the components It would be nice if the web front end could also show what is happening under the covers - perhaps by displaying the SCA diagram and highlighting which pieces are being called when the user chooses to update the alerts from a particular data source.

To: tuscany-dev@ws.apache.org, tuscany-user@ws.apache.org *Apache **Tuscany**: Not the Same Old Architecture* Do you think of the popular term SOA as the Same Old Architecture concept? The Apache Tuscany Project moves SOA (Service Oriented Architecture) beyond buzzwords and vague arm-waving into reality. The project aims to create a next-generation services infrastructure in open source based on the principles behind the Service Component Architecture (SCA). With Apache Tuscany, application developers will be able to create, assemble, and deploy service networks in ways that are not easily done or possible with existing middleware. This webinar will provide an overview of how Apache Tuscany simplifies the task of creating and assembling service-based applications using SCA. It will also cover where the Tuscany project is headed and how it will help developers build tomorrow's applications today. Speakers: Jeremy Boynes and Jim Marino *Jeremy Boynes, Gluecode CTO, IBM Corporation** * Jeremy works at IBM on emerging technologies for Service Oriented Architecture and is an active contributor to Apache Tuscany and other open source projects. Prior to acquisition by IBM, Jeremy was CTO for Gluecode Software and one of the founders of the Apache Geronimo J2EE project. *Jim Marino, Senior Principal Technologist, Office of the CTO, BEA System** * Jim Marino works at BEA Systems in the office of the CTO on emerging technologies. He is currently involved in the development of the SCA specifications and the Apache Tuscany Project.

If you would like to get closer involvement with the evolution of the specifications, you can now apply to join the OSOA Supporters group. The OSOA Supporters have a special controlled-access area on the www.osoa.org Wiki site, which gives access to the minutes of the regular specification conference calls and which provides a discussion Forum which allows for discussion of any topics relating to the specifications and to the issues that are currently under discussion within the collaboration. To become at OSOA Supporter, please go to the following page on the OSOA site: http://www.osoa.org/display/Main/OSOA+Supporters+Home You will be asked to sign a simple Feedback license - this is similar in nature to the ICLA agreement that you must sign in order to contribute code to Apache. The OSOA collaboration specifications are published under generous Royalty-Free terms and the collaboration needs to ensure that any detailed feedback that you give on the specifications is donated in a way that meets those terms. Individuals may join the OSOA Supporters group as well as companies.
