Welcome

Welcome to our blog about all kind of topics that are related to software development. We blog about:

SOA, BPM, EDA, ECM and all the other buzz words. Beware some post might not be so common as you think. We are not scared to go against main stream thoughts.

Technologies like java, maven, springframework, OSGi and front end technologies and frameworks like jQuery, DWR, Flex.

Finally to make this happen we need tools and of course a Mac (well some of us do). So we blog about that as well.

Public Transportation pass woes….

The Netherlands is currently in the middle of a large project to change the way we pay for public transportation. We are moving from paying with a cardboard strip (called the "Nationale Strippenkaart", which must be stamped by the driver of the public transportation vehicle you get on) to a new system (the OV-chipkaart) involving an RFID chip on which you can preload money or one or more subscriptions. The idea is not new (the Greater London Oyster Card is a well-know example) but this is the first time I know of that it has been done on a nationwide scale.

Needless to say there have been problems along the way. Michel van Eeten, professor of Governance of Infrastructures at the Delft University of Technology, recently gave an interview to the Dutch engineering magazine De Ingenieur in which he explained how the project is suffering from an implicit choice of offloading all of the project risks (security, privacy, and so on) onto the customer. A few days ago I had a similar experience with problem offloading onto the public by this project…

Yes! REST really is not the same as HTTP!!

By now I’m sure everybody has at least heard of REpresentational State Transfer (REST). REST is an architectural style that was first properly described by Roy Fielding in his doctoral thesis. Since Fielding published his thesis in 2000 the term REST has become very popular among web developers. Mostly for the wrong reasons of course — REST and the derived term RESTful have morphed into marketing jargon for people who really mean "building a web site" when they say "implementing a RESTful architecture".

One of the things that has gone wrong in the area of REST-the-popular-interpretation is that people think that "doing REST" is the same thing as "using HTTP" (another thing is that they think that REST is something you can do). The reason of course is simple: most people use the term REST to mean building a web site. And you use HTTP for that. And in fact I thought it was not a wholly unreasonable position because one of the constraints of the REST architectural style is such that you really would not want to use anything but HTTP as a rule.

However, today, all of a sudden, I stumbled on ultimate proof that REST really is as independent from HTTP as Fielding claims: a piece of software that uses the REST architectural style but not HTTP.

Axon Framework 0.6 released

Today, I released version 0.6 of the Axon Framework. 0.6 has many new features and is another step towards full production readiness. There is still some work to do, but first, let’s take a look at what has changed…
