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 […]

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 […]

I did not have a change to attend the WWDC this year so I was excited when I read that Apple was organizing ‘Leopard Tech Days’ around the world. Including in my home town, Amsterdam!
It was organized at the Hilton and they took good care of us. Nice breakfast buffet, nice lunch. Hilton Amsterdam style: […]

Some people don’t understand why I still write most of my (non-Java) code in GNU Emacs. Here are seven good reasons:

Emacs editing environment, Part 1: Learn the basics of Emacs
Master the Emacs editor and delve into the depths of its most advanced editing commands that have made it famous. The open source Emacs editor (one […]

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.

We’re doing a event photo gallery […]

I’ve been reading a lot about Android now that they have opened up for developers. The videos are specially nice to see.
Android is really awesome. If Android can gain market share, and I think it certainly can, then it can break open the WindowsMobile/Symbian/J2ME mess that we are currently in. All those platforms are terrible […]

Being in the office (thanks Aldert/Milton) with nothing but a big screen and no crying cat climbing up my legs certainly helps
I just committed a bunch of good improvements to the WSF framework. I ‘generified’ some of the WSF classes and also introduced a WebServiceActionContext.
The WebServiceActionHandler now looks like this:

public interface WebServiceActionHandler<Account extends […]

I’m making a serious effort to bring my C++ skills up to date. It’s not that I don’t like Java anymore, I think it is great, and I am certain I will be doing Java related projects for a long time. It’s just that I want to broaden my scope so that I can acquire […]
