OpenJDK 6 b18 Implements New Component Delivery Model
Joe Darcy has announced OpenJDK 6: b18 Source Bundle Published. This is the first release that implements the new delivery model for JAXP and JAX-WS, which Joe wrote about a couple weeks ago and last August.
In his August entry, Joe explained the problem that was driving the switch to a new component delivery model:
The JDK includes many logically distinct sets of APIs. Some of the APIs naturally live in the JDK and evolve at the pace of the JDK; other APIs are effectively maintained externally, but are also shipped as part of the public API provided by the JDK. Two APIs in the latter camp are
jax-ws, both of which natively live in the GlassFish project.
Currently, those components are maintained under separate version control as part of OpenJDK in the
jax-wsrepositories, respectively. Code in these components is periodically synced with changes from the upstream masters, with some
title="OpenJDK 6: Logistics of Partial Merge with 6u10">nontrivial overhead.
With the new delivery model, implemented starting with OpenJDK 6 b18:
the JDK build no longer tracks a copy of the
jax-wssources under version control. Instead source bundles from the upstream teams are used. The
jaxp.propertiesfile in the
jaxprepository contains the default URL from which the source bundle is downloaded as well as the expected checksum for that file. The analogous setup is used for
jax-wsin its repository.
This doesn't mean that you cannot use alternate JAXP or JAX-WS bundles in your own OpenJDK builds. In JDK 7: New Componenet Delivery Model Delivered Joe shows how to set variables in an Ant build to download and include an alternative JAXP bundle.
With this new delivery model, I look forward to low-overhead and coordinated updates to
jax-wsin OpenJDK 6 and JDK 7.
OpenJDK 6 b18 also includes many security updates and a backport of Nimbus look and feel from JDK 7. See the OpenJDK 6 b 18 changes summary page for the full set of changes, including links to the bug database items.

Joerg Plewe talks about how sometimes Simple things just work .... Ant 1.8:
I recently got pointed to that link: http://java.dzone.com/news/ant-18-scanning-leaves-171. I read the news with some pleasure reminding me that I still like Ant based builds very much over Maven in many cases. Of course there are a lot of well maintained projects on the web that work very well with Maven. You never know how many enthusiasts-hours have been spent to make that happen. However, in smaller business projects I experienced the situation to be slightly different. Not a single one I came across ran out-of-the-box. Some actions had to be taken upfront...
Markus Karg discusses What HATEOAS actually means:
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 understand what his dissertation tells us; no need to guess), the longer I follow those (in part ridiculously wrong) assumptions and myths, the more myself feels urged to stop those and shout: "Guys, before discussing your ideas, first learn what Mr Fielding's idea was!" ...
