Spring 2.5 has some great improvements that make configuration much simpler. One that I very much like is the auto detection of components in the classpath. The Spring 2.5 documentation on this subject is worth reading. It also gives a nice and simple example.

I’ve created a 2.0 branch in the polarrose-wsf project where I want to try out some new ideas.
Some things on the list:

Merge the wsf and wsf-examples into one maven project as modules (already done)
Merge the projects on Google code
Add the wsf-client module to the project
Depend on Spring 2.5 for auto detection of action handlers. Just […]

Now that SimpleDB is out of it’s secret stealth beta I thought it was a good idea to make my Amazon Python modules available on Google Code.
I’ve written these for Polar Rose but as usual they are happy to release things like this under an open source license.
What the package contains is two things:

There is an excellent article on the Mathematic blog by Stephen Wolfram, who is still, after 21 years, the main architect of the Mathematica core.

If one does a good job at finding the primitives, then one can build a very broad system that gives one not just the functionality one was first thinking about, but […]

Looking back at a year of too much code and traveling, here are some things worth mentioning about Polar Rose.

We won the award for Best Technical Innovation at SIME’07.

How do you recognize a familiar face in a crowd? What is intuitive for the human eye has not been easy for the computer. The winner combines state of the art technology in computer vision with the finishing touch of human feedback.

Proud colleagues, Mikkel BizDev, Jan […]

I just added basic support for multi-value parameters to the Polar Rose Web Service Foundation project. This was mostly done using some Java reflection and generics magic.
An example will explain it all. Here is a simple web service action implementation that takes a list of integers as a parameter.
