Web Services and XML
It actually happened a few weeks ago already, but I simply didn't find the time to spread the word earlier -- just too much other stuff to do (see end of posting), so I tell you now: WebDAV Support for JAX-RS 1.2 is out!
What has happened since 1.1?
First of all, 1.2 is a complete internal overhaul, which not only finally is covered with unit tests rather completely (which revealed several...

You want JAXB to unmarshal singletons? You already spent lots of time coding rather complex workarounds applying XmlAdapters and afterUnmarshal callbacks? The solution is astonishingly simple. Possibly so simple that nobody in the JAXB team ever thought it would be necessary to put the word "singleton" somewhere next to the JavaDocs for this... Anyways, here is the solution:

JAX-RS 2.0: A first interim report
It's been a few months already that the expert group of JSR 339 started discussion about the details of JAX-RS 2.0. The target defined by spec lead Oracle are clear: Java EE 7 shall have a RESTful API that augments current JAX-RS 1.1 API by (among others) a Client API, HATEOAS support and asynchronous invocations. So what's the status with state?
As three corner...

There are times when things hurt so much that you feel urged to blog about them once solved. This is one of them.
Our company is using XSL heavily for reporting (generating vector charts in PDFs on the fly from data analyzed by GlassFish), so it is not very amazing that we found some bugs in the XSL transformer (a.k.a "JAXP Implementation") contained in GlassFish. As we're not so fast...

What it means to speak German fluently and to be able of C++
Several years ago one of our key coders moved from the south of Germany (where our HQ is located at the Black Forest) to the cold and rainy north, so we had to to find a suitable substitute. After screening lots of applications, we picked few to invite for an interview. It declared the candidate's ability to speak German and C++. So she...

RESTless about RESTful
These days there is much discussion about REST and HATEOAS, and many people feel urged to reinterpret what HATEOAS means or what Roy Fielding's often-cited dissertation allegedly would say in their understanding, and what HATEOAS should be implemented like therefore. While I first felt amused about this "dispute about nothing" (just ask Mr Fielding if you don't...

For many years I am using XSLT now for a lot of tasks in both, development and runtime environments: Source generation, creating HTML from XML data, or even rendering SVG vector graphics from XML finance data. But what really bothered me was that the XSLT transformer contained in Java (even in Java 6's latest release) was just able to do XSLT 1.0 but not XSLT 2.0. XSLT (and XPath) 2.0 comes with...

Over the past decade, OpenSource became a big hype. At the peak of the hype, big stakeholders like IBM, Oracle and Sun (and even Microsoft and SAP) turned a lot of their previously proprietary code into OpenSource. While they tell us that they do it because they are so noble and like to exploit the community's knowledge, typically the open sourced software is only for free in part or is still...
