Announcing JBoss DNA 0.5
by Randall Hauch
Hot off the presses is the latest release for JBoss DNA [1]. Our
Getting Started document [2] and Reference Guide [3] were both
completely rewritten to be more thorough and better reorganized.
Among the features are even better JCR compatibility, a RESTful web
service for accessing and changing repository content (via RESTEasy),
a new configuration system that leverages a configuration repository,
an read-only SVN connector, a faster federation connector with a fork-
join algorithm, an improved connector framework, and updated
connectors and sequencers. That's just some of what's in the release.
To recap, here's a brief summary of the project and what we're building:
JBoss DNA is a JCR implementation that provides access to content
stored in many different kinds of systems. A JBoss DNA repository
isn't yet another silo of isolated information. Rather it's a JCR view
of the information you already have in your environment: files
systems, databases, other repositories, services, applications, etc.
To your applications, JBoss DNA looks and behaves like a regular JCR
repository. Using the standard JCR API, applications can search,
navigate, version, and listen for changes in the content. But under
the covers, JBoss DNA gets its content by federating multiple back-end
systems (like databases, services, other repositories, etc.), allowing
those systems to continue "owning" the information while ensuring the
unified repository stays up-to-date and in sync.
Thanks to the whole JBoss DNA team for their hard work on this
release. The team has grown steadily over the last 6 months - we're
now at 10 contributors that are all stellar. With 0.5 under our belt,
our next release will be focusing on passing the remaining parts of
the JCR TCK (Level 1 and Level 2, plus some optional features). As
always, if you're interested in helping, please join the dna-dev(a)lists.jboss.org
list or pop into our IRC room (irc.freenode.net#jbossdna).
Regards,
Randall

few questions about connectors and JCR
by Feu Teston
Hi Guys!
I'm starting to use JBoss DNA on my project, and I spent the last few
days taking a look on documentation and also on source code and unit
tests.
So, a few things I didn't find or I didn't understand well:
1. Is it possible to configure another JCR implementation for DNA? If
yes, can you guys send me a link or some instructions about how to do
that?
2. Connectors are pretty disconnected to JCR stuff (witch is very
good). But I didn't find yet where the information retrieved by the
connectors go to the federated JCR. Is it done by the
RepositoryListeners? If you guys can, please tell me some unit tests
to take a look or some send me some documentation to take a look.
So far, so good. Thanks a lot for the help!
