I just finished listening to an episode of the Connected Show podcast. Most of the episode is an interview with Ted Neward about the Apache Stonehenge project. Ted brings up some really good points about the project.

1. Everything is in the open on the mailing list. Right now we are trying to decide what all will end up in our 2nd milestone release. If you want to have a say please jump in and give your opinions.

2. The projects is completely open source so you can see what others are doing and decide for yourself if the code follows “best practices” or if you have a better way. I have to admit that personally I sometimes find the idea of having thousands of people (I wish it were that many but some day it may grow to that) doing a code review on my code a little intimidating.

3. Microsoft is committed to interoperability. This is just one of several interoperability projects that I am aware of. While Microsoft is still competing and trying to make better products so we will all buy them they also have gotten the message that they have to play nice and are working hard to make sure that they do.

I really had to laugh when Ted explained that we aren’t espousing “best practices” because historically what is considered best practice when a technology is new is rarely what is best practice many years later. I have talked with some of the others on the project at different meetings we are attending. We are trying to get interoperability first and foremost with thought being put into how to make it easier to test the interoperability and also if we can provide test harnesses to make it easier to test the growing matrix of configuration and interoperability options.

If you want to see how web service implementations from various vendors can all work together check out the project at http://incubator.apache.org/stonehenge/

Today there were many pieces of good news for the Apache Stonehenge project. I have been working on the project for the last few months. There has been a lot of work (mostly by others) to make sure that we have a good quality release. The first is that we have released the M1 milestone that shows interoperability between PHP, Java, and .NET implementations of the application. You can mix and match the different front ends, business processing services, and order processing services as you want. I will paste the announcement below for those who are interested.

The second piece of good news was that the Stonehenge project was a large part of the demo given during the keynote at the Java One conference today. Greg Leake from Microsoft and Harold Carr from Sun demonstrated Stonehenge working with a Java implementation created by Sun.

The third piece of good news was that Sun donated their implementation of the Stocktrader application to the Apache Stonehenge project. Now there are multiple Java implementations.

Since the whole purpose of the Stonehenge project is to show interoperability between different web service stacks I would love to see other vendors such as BEA (Oracle) and IBM also contribute solutions. For many years we have been talking about how standards will help the industry with interoperability. The Apache Stonehenge project is showing concrete proof of how that works and better yet with the code and configuration files available anyone can examine how it was done and duplicate it in their mixed environment.

As promised earlier here is the text from the announcement of the Stonehenge M1 milestone.

We are pleased to announce the release of Apache Stonehenge
(incubator) version M1.

Apache Stonehenge is a set of example applications for Service
Oriented Architecture
that spans languages and platforms and demonstrates best practise and
interoperability.
The aim of the Stonehenge project is to develop a set of sample applications to
demonstrate seamless interoperability across multiple underlying
platform technologies
by using currently defined W3C and OASIS standard protocols. By having
a set of sample
applications, with multiple language and framework implementations
will become a useful
and important part of the SOA landscape. It will:
 
* illustrate and develop best practice for interoperable
applications that communicate
via distributed protocols,
* demonstrate interoperability between platforms,
* provide sample code upon which SOA developers can build,
* help identify interoperability issues and their solutions, and
* build confidence in cross-platform deployment of SOA technologies.
 
Disclaimer: Apache Stonehenge is an effort undergoing incubation at
the Apache Software
Foundation (ASF), sponsored by the Apache Incubator 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.
