Semantic Web Drools Module, Request for Feedbak
by Xavier Breton
Hi,
I'm looking for feedback, I'll develop a Semantic Web Drools Module that
will be the subject of my Master Degree Tesis.
The idea is to use Eclipse Modelling Framework (EMF) for prototyping and
follow a Model Driven Architecture (MDA) where the source language is
Semantic of Business Vocabularies and Business Rules (SBVR) and the target
language is Drools DRL.
The mapping could be (PIM level):
- Semantic Web Rule Language (SWRL)
- Ontology Web Language (OWL)
- RuleML
- Rule Interchange …
[View More]Format (RIF)
- REWERSE Rule Markup Language (R2ML)
It could be added to the module at the source UML or Entity Relationship
like models to transform the models into SBVR.
Regards
Xavier Breton

Attach custom editor on guided decision table cell
by c3310082
Hi,
We would like to render a custom editor when a user double-clicks on a cell
that is present in web guided decision table in Guvnor 5.1 (or later). The
custom editor needs to be invoked for cells that represent a particular fact
model attribute only.
This is somewhat similar to WS custom forms functionality available for
guided business rules.
So far we have seen the
org.drools.guvnor.client.decisiontable.GuidedDecisionTableWidget class that
contains implementation for:
public void …
[View More]onCellDblClick(GridPanel grid,
int rowIndex,
int colIndex,
EventObject e)
in the GridCellListenerAdapter class that opens up text editor or drop down
editor.
We're new to GWT and Guvnor so would appreciate it if anyone can provide the
high level steps.
Thanks

Guided Editor in BRMS / Guvnor Version 5 (Snapshot of 26 June)
by Paul Browne
Folks,
For various reasons I'm trying out the Guided Editor for Business Rules in
the Guvnor Version 5 (Snapshot of 26 June from Hudson, deployed on JBoss App
Server 4.2.2GA).
I've created the Package / Category and uploaded a simple fact model (as
works in BRMS version 4). I create a new business rule using the guided
editor and the screen shows successfully with both 'When' and 'Then'
parts.Assume the next question is due to me missing something, but wanted to
double check:
When I press …
[View More]the green '+' to the right of the screen I am shown the message
/ dialog layer saying '
*Add a condition to the rule... *or* Add an action to the rule.
*Problem is that there doesn't appear to be a way of adding a condition or
action. The only thing I'm seeing in the logs is
* (Contexts.java:flushAndDestroyContexts:335) could not discover
transaction status
*Am I missing something or should I come back to Guvnor later in the
development Cycle?
Thanks
Paul

Drools on android
by Justin King
Hi All,
I'm wondering if anyone has tried to use drools in a google android
application, and if so what problems did you have? I'd also be interested to
know if its even possible!
Thanks!

Guvnor XSRF attack?
by Michael Anstis
Anybody else see these errors in Guvnor (5.2.0.M1)?
ERROR 03-02 16:35:38,914 (LoggingHelper.java:error:70) Blocked request
without GWT permutation header (XSRF attack?)
java.lang.SecurityException: Blocked request without GWT permutation header
(XSRF attack?)
GWT2.1 introduced support for preventing XSRF attacks; see
here<http://groups.google.com/group/google-web-toolkit/web/security-for-gwt-ap...>
.
I get these errors quite regularly (Firefox 3.6.13, Ubuntu 10.10) both in
hosted …
[View More]and web modes (Tomcat 6.0.30). I've looked through the GWT source and
(at least in hosted mode) the additional HTTP header to prevent these errors
are added as part of GWT's client-side serialisation before POSTing to our
RepositoryServiceServlet. I can't therefore explain why I therefore get
these errors. In my experience; once the error has occured and dismissed the
page\function\operation can be repeated without the error re-occuring (i.e.
view "Business rule assets" in the Tree Browser and it may fail the first
time; however works the next and the next... until the server is restarted,
when the cycle continues). The errors can be completely removed by
overriding GWT's
com.google.gwt.user.server.rpc.RemoteServiceServlet.checkPermutationStrongName
to not check the HTTP header and simply return; however this effectively
removes XSRF protection (although not implemented pre-GWT2.1 and hence not
in Guvnor <=5.1).
I put the email out so people are aware (we switched to GWT2.1 for 5.2.0.M1)
so our users may start to report the same error; in which case we should
perhaps be prepared for the quick fix...
With kind regards,
Mike

Branch date for 5.2.0.M2 is Sunday 20-MAR-2011
by Geoffrey De Smet
Hi guys,
It's time to temporarily switch your mind from progressive mode to
conservative mode,
as the 5.2.0 release is coming closer:
We're estimating *the next branch date (for M2) on Sunday 20-MAR-2011.*
On that date the M2 release branch will copied from master and any new
commits won't make the M2 release,
unless they are manually merged to the release branch.
The release itself will follow a few days (or more) after that M2
release branch is thoroughly tested.
So try to get all your …
[View More]bugfixes in master before that date.
And try to get your current experimental and unstable features stable by
then.
And try to wait with adding new experimental and unstable
improvements/feature until after that date
(unless you still have the time to get them stable).

Guvnor 5.2.0.M1.x : Maven config fix
by Sayhi Aymen
Hi everybody,
I checked Drools 5.2.0.M1.x sources yesterday in order to look with more
insight to *Guvnor *internals.
I built the whole project with *Maven* and that was ok.
But when I tried to run *Guvnor *with *Maven *(mvn gwt:run) I was surprised
to see that the *Maven *config do not allow that, I get a lot of errors !
Thankfully I fixed that (after a hard night) and I want to contribute with
that *Maven *config fix.
Are you interested ?
By the way, I've already been *Maven *maintainer …
[View More]of an open source project
on sourceforge, *Gilead<http://noon.gilead.free.fr/gilead/index.php?page=thanks>
*. And I can help you in the future for anything related to *Maven*.

Best Regards

Large Decision Table Example Wanted
by Mark Proctor
We are looking for real world example decision tables that are 2K or
even 5K rows big or even 10K :)
This will allow us to demonstrate what really large decision tables look
like as well as allowing us to stress test our web based system and show
that it can handle problems of that size.
Anyone able to donate such an example, or can point to an existing one?
It is important that such a decision table comes with enough unit tests
to show that it contains a valid data set.
