WebDav and rules repository
by Michael Neale
For anyone who knows anything about JCR/JSR-170, there is a "node type"
called nt:file, which represents a file type resource.
We have a "asset" type node at the moment, which is kind of analagous to a
file (and it is stored in folders).
As the repository is kind of like a filesystem (ine one sense, in another
its queryable like a database and presented like one) it is possible, if we
choose, to expose things via WebDAV for applications like Excel to save
into. This opens up a lot of possibilities.
I wanted to get peoples thoughts on making our "asset" node be an "nt:file"
type - from an API point of view most of this can and will be hidden, more
of a small structural change to allow future flexability. At the moment the
asset type just stored content as a string or byte[] as needed - with an
nt:file it would be slightly more formally defined to be closer to a file.
Is it worth the effort? Is this something that excites or interests people:
FYI, if one was to browser the repo as a (virtual) file system, it would
look something like:
/root
/packages
/package name
/assets
/Rule1.drl
/Rule2.drl....
/Something.xls
/another package ....
/categories ...
/statuses
/configuration ...

Build work
by Mark Proctor
We can build with both ant (using embedded maven for dependencies) and
maven itself. However just being able to build software is a far cry
from a build that can do full distribution build releases.
What I'm struggling with at the moment is a way to emulate the ant
process for javadocs - you'll notice that we check for a ydoc directory
and produce ydoc projects if thats present. I was experimental with
profiles to try and get this workign, but ran out of time, part of the
issue also seems to be you have to "install" the ydoc libraries, which
seems a bit OTT.
Then there is the dist-all targets, where we build the various binary
and src jars.
We also use ant for all our documentation building with docbook.
Finally I'm looking to integrate the Eclipse plugin build process, not
yet done, into ANT - that work will also need to be migrated to maven.
While you are at it, it would be good to get things like cobetura and
unit test reports :)
Good Luck.

JBossRules 3.05 & Axis2 1.1.1
by Matthias Benesch
Hello,
I tried to set up my first example, using a rule engine. The example works fine, but when I move the rule engine into a WebService using Axis2, my imports in the rule can no more be found. I already found some posts, dealing with the same Problem, but no solution. I think it should be something wrong with the classpath. But is it Axis? Or JBossRules? Or me? Any hind?
best Regards,
Matthias

checkin and save
by Mark Proctor
Mic,
My current code in the svn to jcr sync is failing because
repository.save() is not setting version numbers. The checkin() method
seems the only way to have something increas the version number, also
does a save and a checkin at the same time, but its at an asset level,
not a repository level:
this.node.setProperty( VERSION_NUMBER_PROPERTY_NAME,
nextVersion );
this.node.getSession().save();
this.node.checkin();
However I need a unit of work to be atomic. So save() is done at the end
of the session, when all actions have been applied, when I call "save" I
want version numbers increased.
