WS-Policy and more

WS-Policy Implementation Goes Open Source

We have been working on an implementation of WS-Policy and WS-PolicyAttachment as part of WSIT in project Tango for a while now and I am very pleased to see the first results of that work out in the open now. Project Tango is a Sun initiative focused on delivering interoperable Web services technologies. Web Services Interoperability Technology (WSIT) is an open-source implementation of next generation Web services technologies that deliver interoperability between Java EE and .Net to help you build, deploy, and maintain Composite Applications for your Service Oriented Architecture. It is focused on four main categories: Messaging, Metadata, Security, and Quality-of-Service (QoS).

I believe WS-Policy will become a major building block for web services. From a developer's point of view, WS-Policy is a major step towards relieving you from the infrastructure related coding and is allowing you to focus on the business problems that you really want to solve. And it does that in a completely interoperable fashion across system and programming language boundaries. You can express how to secure your service, whether you need to use reliable messaging or transactions, etc. and your services and clients will pick up your settings automatically without a single line of code being written. We felt WS-Policy was significant enough that we co-submitted it to W3C.

While there is still more we want to implement, the current implementation is sufficiently complete and stable to have cleared all the interop scenarios at the WS-Policy workshop in April. We spent much thought on making the implementation as seamless as possible to developers. In fact, you will not find any policy API. Policies are configured through NetBeans, which includes them in WSDL or in a separate configuration file, and deploys them with the application. That's it. Both Web services and clients configure themselves when they start without any intervention from the outside.
