Tango Overview - Now Translated in Chinese

"Project Tango: Adding Quality of Service and .NET Interoperability to the Metro Web Services Stack" - The original article, introduced here, provides an introduction to how different Quality-of-Service, such as Security, Reliability and Transactions are enabled in Metro. One of the core benefits of Metro is interoperability with .NET 3.0 and the article describes how that is baked in the Web services stack.

The same article is now available in Chinese at Sun Developer Network China. Thanks to the Globalization Team in China for completing this effort, and Zhen Tao in particular who did the translation!

Metro runtime is available as part of GlassFish v2 UR1 and tooling is available in NetBeans 6.

Let us know if you'll be interested in creating a localized version of this article.

JavaOne 2006 Keynote WSIT Demo

A new sample is added to WSIT samples that shows an enterprise Web service enabling integration both within and across boundaries. This sample demonstrates a price quotation service that provides list price to clients based on the product identifiers. The client makes a request to a Retail Quote Service (RQS)  which then communicates with multiple Wholesale Quote Service (WQS) to get the best price and returns that to the client. In the first version of this sample, the client and all the service endpoints (RQS + 2 WQS) are built and deployed using WSIT. A later version of the sample will replace one of the WQS to be built and deployed using Windows Communication Foundation (WCF) and also have a WCF client, in addition to WSIT client, invoking the RQS.

The sample demonstrates secure reliable communication between RQS and two WQS. It also demonstrates secure MTOM between the client and RQS. A picture is worth a thousand pictures and so this graphical representation should help visualize.

This sample was demonstrated in JavaOne 2006 keynote and used as the basis of my JavaOne 2006 technical session (TS-5540). In case, you need more technical details, the StarOffice version of slide has speaker notes and animation.

Instructions to check out the sample

This sample can be checked out using the instructions given here. These instructions will retrieve WSIT sources along with the sample sources as both are required to build, run and deploy the sample. The sample exists in wsit/wsit/samples/pricequote directory. Once checked out, follow the instructions in readme.html in the pricequote directory to build and deploy the sample on GlassFish.

Tango at Microsoft JavaOne party

I attended Microsoft JavaOne party Wednesday night. It was great to meet their developer evangelists (Jas, Nima and Woody to name a few). I specifically spent some time with Mohammed Akif who is a member of Microsoft Architecture Editorial Board. He is an ex-Sun employee and used to be a Senior Java architect and co-authored several Java books before joining Microsoft. I recommend reading his extensive coverage of JavaOne so far.

BTW, check me and Kirill doing Tango at the party here. I'm now relaxed after literally living at work for the past few weeks to pull the keynote demo.

JavaOne 2006 - Project Tango Keynote Demo

We, at Sun Microsystems, have been working with Microsoft for past several months on achieving interoperability between Java EE and .NET technologies. Web Services Interoperability Technology (WSIT, a.k.a Project Tango) is Sun's Web services interoperability portal and provides all information on that effort. Earlier yesterday, we gave a demonstration of our work so far in JavaOne 2006 keynote. The main points from the talk is that Project GlassFish community and Windows Communication Foundation make Interoperability a Reality TODAY.

A video clip of the keynote demo is available here. This clip starts with our keynote presentation where Nick Kassem explains the business scenario which shows how Web services technologies enables integration within and across business boundaries. Watch me explaining the development environment to Jeff Jackson from 3:46 to 4:48. All the tools and technologies used in the demo are available today. And then Kirill Gavrylyuk shows an interoperability demo between Infocard and Sun's Secure Token Service. A picture is worth thousand words, here is a graphical representation of the scenario.

On the right, a Retail Quote Service (RQS), running in Sun-managed environment, uses Wholesale Quote Service (WQS) to serve car quotes to Java and WCF consumers shown on the bottom left. RQS also gets competitive bids from a WQS running in a Microsoft managed environment. The clients talk to the RQS secure MTOM, RQS talks to WQS using a Secure and Reliable Connection. Each managed environment has it's own identity provider, also known as Secure Token Service or STS in short. A trust relationship between the two environments is enabled by a trust relationship between a priori trust relationship between STS.

We also plan to share the demo code in the near future and I'll post another blog when it's available.

A specific Call To Action for you is to:

Introducing wsit.dev.java.net

• 637 new Java source files
• Approx 111K lines of new code
• How To Documentation and Samples
• Integrated NetBeans 5.5 tooling
• Implementations of WS-Policy, WS-Security Policy, WS-Metadata Exchange, WS-Security 1.0 and 1.1, WS-Secure Conversation, WS-Trust and WS-Reliable Messaging.
• Leverage existing JAX-WS programming model
• User list and interoperability forum

These are some of the statistics of Sun's open-source implementation of next generation Web services technologies that deliver interoperability between Sun's Application Server 9.1 PE (part of GlassFish) and Microsoft's Windows Communication Foundation (WCF, aka Indigo). This implementation is known as Web Services Interoperability Technology (WSIT) and is part of Project Tango. Sun delivers on the initial promise of facilitating interoperability with .NET platform by embracing and open sourcing implementations of key WS-* specifications. Read more about the various technologies involved here.

We, engineers in Sun, have been working directly with Microsoft engineers ensuring out-of-the-box interoperability for WSIT artifacts with WCF. Read about Sun's participation in previous plugfests (Nov 2005 and Mar 2006).

NetBeans 5.5 IDE and documentation is released along with the source. This facilitate users to download the WSIT bundle and try the pre-existing samples or create new ones from scratch without remembering the exact syntax of config files or any other option that might be required to configure the sample.

Everything mentioned above can be downloaded at wsit.dev.java.net.

Download it, try it and pretty soon you'll find yourself completely immersed. And we do appreciate your feedback.

Microsoft joins JCP

On the second anniversary of Microsoft and Sun entering into a broad technology collaboration, Microsoft exceeded expectations on this relationship when they decided to join the Java Community Process (JCP). JCP is an open and participative process to develop and revise the Java technology specifications, reference implementations and test suites. The exact details of their participation are still being worked out but they've already signed the Java Specification Participation Agreement (JSPA) and are now a member of the JCP.

Microsoft and Sun engineers have been working very closely in the recent months to ensure interoperability of enterprise features. This will ensure that Sun's Project Tango, that will be released on java.net and installable on Glassfish, will interoperate with Microsoft's Windows Communication Foundation (aka Indigo) out-of-the-box. After achieving great interoperability results between the two companies in the recent plugfest (Nov '05, Mar '06) meets conducted at Microsoft campus, Microsoft expressed interest in participating in the JSRs relevant to their enterprise feature.

This is an extremely pleasant surprise to the entire developer community since Microsoft's participation in the JCP will ensure that Microsoft can interoperate, not only with Sun, with the entire Java platform.

Interoperability between Microsoft and Sun products, as mentioned above, is a reality but every thing else said above is only wishful thinking since this blog is written to celebrate a special day of the year.

Happy April Fool's Day!
