Fernando Meyer or Michael Neale..any comments or thoughts?
I guess I am of the belief that
drools-repository/src/main/resources/log4j.xml should NOT
be bundled into drools-repository.jar because it causes
exactly the problems described by Geoffrey De Smet below.

Hi All. Just a quick few tips on if you are editing a large documentation
XML (like the examples section).
* Don't ever update from SVN if you have some edits in progress. Editors
like XMLMind and such can tidy up the XML such that the merge will be bad
(even if it detects no conflicts, it can still wipe stuff out)
* If you are doing small edits all over a document, check in frequently (and
*then* update to the latest)
* When you are finished, try to commit - if the versions are out of date,
don't update. Take a copy of your local one, and then revert it and update
(so you have the latest).
* You will then need to copy in the section you were working on.
This is not ideal, as it basically is manual merging relying on the fact
that the <section> you were editing was not also edited by someone else, but
other approaches seem worse.
If anyone has other tricks for XML merging, let me know (there are probably
some tools out there to do a better job).
As no one from the community was willing to do it :( we've been building
out the examples documentation, although it's slow going. Anyway I've
put up a latest export of just the examples docs, please read and get
Still plenty more to do there, but enough to be useful now :)
I find that one of my applications (a webapp running on jboss-4.2.1ga )
stops logging when I added drools.
Actually it does not entirely stop logging, but it just becomes very
very quiet (ERROR only).
After some digging I discovered that drools-repository.jar contains
log4j.xml and when I deleted that file from the jar,
my webapp logging returned to normal levels.
Is this expected behavior?
Finally got the documentation building and editor up and running. Was
looking at filling some gaps in it - I'm thinking of some of the
remaining samples or around the BRMS.
Is anyone using StatelessSession.getQueryResults(). Realised that it was
a mistake adding that. the idea of StatelessSessionResult is you have
something that is potentially serialisable. To execute that method then
you have to have a refernce to the entire WorkingMemory and that must
reference the RuleBase, so it suddenly makes that a little heavy. I'm
thinking of removing that method and also combining it with the ability
to specify only which inserted objects and set globals are exported as
part of a StatelessSessionResult, if not specified all inserted objects
will be made available and no globals.
I'm not sure that querries make any sense on a stateless session anyway,
This is an API change (removing getQueryResult), and if people are using
it I will leave as is, but I'm not sure if anyone will be using that
anyway. What do people think?
I downloaded 4.0.1 source and when I try to build it using maven, I get
the following error. Note that I can build 4.0.0 from the source with
this same command. Obviously I am missing something but I'm a maven
newbie and I really just want to fix a stream leak in drools and not
really learn maven at this point. Any help will be greatly appreciated.

CALL FOR PARTICIPATION
The International RuleML Symposium
on Rule Interchange and Applications (RuleML-2007)
October 25-26, 2007, Orlando, Florida
*** NOTE: The early registration deadline is on 15 September 2007 ***
The 10th International Business Rules Forum
In Co-operation with:
ECCAI, AAAI, ACM, ACM SIGAPP, ACM SIGMIS, ACM SIGART, ACM SIGMOD, IEEE,
IEEE Computer TCAAS, IEEE SMCS, BPM-Forum, W3C, OMG, and OASIS
We invite you to attend the International RuleML Symposium on Rule
Interchange and Applications (RuleML-2007) to be held during October
25-26, 2007 in Orlando, Florida. As this is a 'first-of-its-kind' event,
participants can make a difference about shaping the future direction
and structure of the field, including about rule standards supporting
their own approaches and about their own possible involvement in the
organization of future events.
Co-located with the 10th International Business Rules Forum, the
International Symposium on Rule Interchange and Applications
(RuleML-2007) is the first event devoted to work on practical
distributed rule technologies and rule-based applications. These need
language standards for rules operating in the context of, e.g., the
Semantic Web, Intelligent Multi-Agent Systems, Event-Driven
Architectures and Service-Oriented Computing Applications. After a
series of successful RuleML workshops and then conferences (e.g.
http://2006.ruleml.org), this is a new kind of event where the Web Logic
community joins the established, practically oriented Forum of the
Business Rules community (http://www.businessrulesforum.com) to help
cross-fertilizing between Web and Business Logic technology.
The goal of RuleML-2007 is to bring together rule system providers,
representatives of, and participants in, rule standardization efforts
(e.g., RuleML, RIF, PRR, CL, SBVR) and open source rules communities
(e.g., jBoss Rules, Jess, Prova, OO jDREW, Mandarax, XSB, XQuery),
practitioners and technical experts, developers, users, and researchers.
It is an excellent opportunity, for experienced rule researchers/
practitioners as well as newcomers, to learn more about this
innovation-driven technology market, characterized by strong growth and
commercial opportunities. They will be offered an exciting venue to
exchange new ideas, practical developments and experiences on issues
related to the engineering, management, integration, interoperation and
interchange of rules in open distributed environments such as the Web.
The scope of RuleML-2007 covers all topics relevant to rule-based
technologies, rule interchange formats and rule-based applications as
well as discussions of lessons learned that have to be taken into
account when employing rule-based technologies in distributed,
(partially) open, heterogeneous environments.
The symposium will feature a strong, single-track technical program
* Keynote speakers:
* Ron Ross, Business Rules Solution LLC, USA:
"Business Requirements for Rule Modeling"
* Jürgen Angele, Ontoprise, Germany:
"How Ontologies and Rules Help to Advance Automobile
* Adrian Bowles, OMG, USA:
"Sharing Policy Rules for IT Governance"
* Harold Boley, National Research Council, Canada:
"Are Your Rules Online? Four Web Rule Essentials"
* 2 Invited papers
* 9 Long research papers
* 9 Short research papers
* Industry and demo presentations
* Challenge with awards
* Panel discussion on Web Business Rules
