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 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.

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 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

Potential Job Opening for Core Drools Developer around Guvnor
by Mark Proctor
We are just finalising the details, but it looks like we may have a job
opening for a mid to senior java developer, to work with the Drools team
around Guvnor. I'm particulary interested in a London based developer,
who can work directly with me.
I'll post more details and a reference to the online details once they
become available. In the mean time, if you think you have what it takes,
send me an email.

Request help for source code of accessing excel file using Drools 5.0
by Sanjib Karmakar
Hi
I am new in drools and in my project I would like to access rules in excel
file using drools 5.0
Please provide me the source code for how to access the rules in excel file.
I have done the following code
KnowledgeBuilder kBuilder = KnowledgeBuilderFactory.newKnowledgeBuilder();
DecisionTableConfiguration dtconf =
KnowledgeBuilderFactory.newDecisionTableConfiguration();
dtconf.setInputType( DecisionTableInputType.XLS );
dtconf.setWorksheetName("Tables");
kBuilder.add(ResourceFactory.newFileResource("TeamAllocationExample.xls"),
ResourceType.DTABLE, dtconf);
KnowledgeBuilderErrors errors = kBuilder.getErrors();
if (errors.size() > 0)
{
for (KnowledgeBuilderError error: errors) {
System.out.println(error);
}
throw new IllegalArgumentException("Could not parse knowledge.");
}
KnowledgeBase kbase = KnowledgeBaseFactory.newKnowledgeBase();
kbase.addKnowledgePackages(kBuilder.getKnowledgePackages());
return kbase;
How could I use the POJO for accessing the rule?
Please help me.
Thanks in advance
Sanjib

Re: [rules-dev] Unable to load session snapshot
by Sameeh Harfoush
I solved the problem of JPA, after narrowing it down... i am using snapshot
build number 33671
I was using a single static global variables of KnowledgeBuilder and
KnowledgeBase and using them throughout the StatefulKnowledgeSession
session, this was causing a problem when loading the session snapshot from
DB (http://pastebin.com/EVktxtL7)
What i did to fix the problem that
1- i used the KnowledgeBase by calling ksession.getKnowledgeBase() , after
setting kbase in the session of course
2- and always created a new KnowledgeBuilder to add resources by
KnowledgeBuilderFactory.newKnowledgeBuilder()
