I woke up the other day and realized its 2010. When I was a kid, year 2000 was far, far away (well not quite, but hey when you are 7 years old 13 years is a long time). In 2001 we were supposed to be colonyzing the moon.  In 2010, Jupiter would be within our reach.  And there are reliable reports indicating that  9 years from now flying cars and aritificial life forms...

Our lead Java Today story is JAX-RS with Jersey: An Introduction, by Dustin Marx.

Dustin begins his introduction with: The JAX-RS (JSR 311: The Java API for RESTful Web...

For meanwhile more than 25 years I am writing computer programs. More than a decade I spent with programs accessing databases, virtually always relational ones. I soon learned that this is rather hard work. Not only that you need to know about the theory behind RDBMS iself, but also you need to know the technical APIs (like ODBC, ADO, RDO, JDBC, JDO, JPA, CMP, ...), the structure of...

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...

Jersey provides built-in support for JSONP and this blog demonstrates how to benefit from this feature. When JSONP is a good option? The controversial around JSONP is the fact that using JSONP your...

Education

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.

JSR

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...

Web Design

Over the weekend, I was reading Mark Pilgrim's great book on HTML5 - and when I got to the part about the semantic tags, I thought it might be worth a quick mention. In case you've missed out on HTML5 in general (and don't want to take the time to read that book I linked above), the idea behind semantic tags is that many sites use div blocks to mark out the same kinds of content, over and over....
