new-bie problem
by Rajeev Dave
Hello all,
I am working on the excel driven rules application and have a small query. The app is for a mobile service provider. The following are the requirements.
The company has 3 plans(apart from a default plan) which a user can opt from while taking the connection. However if the user does not choose any one, company grants a default plan to the user.
Problem statement: I need to default to a plan using rules and not hardcode in my javacode. The rules should say that the user has not chosen any plan, hence grant him the default plan. I am not able to comeup with an excel sheet containing the rules.
Rgds,
rajeev

CfPart: International RuleML Symposium on Rule Interchange and Applications (RuleML-2007)
by Adrian Paschke
[ our apologies should you receive this message more than one time ]
=====================================================================
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 ***
http://2007.ruleml.org
=====================================================================
Co-located with:
The 10th International Business Rules Forum
http://www.businessrulesforum.com
=====================================================================
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.

4.0.2
by Mark Proctor
We will be releasing 4.0.2 on the week of the 10th, so it's a quick
release. Calling functions and static method calls with MVEL is already
fixed. It looks like the jci/janino recursion on import bug has been
fixed, so we'll update those for 4.0.2. The MVEL code completion and
debug will also be fixed for 4.0.2. We will try and fix
accumulate/collect for querries but if it gets difficult they may have
to wait.

single result
by Tim.Nguyen＠expeditors.com
Is there anyway to only display 1 error message in the RHS instead of
displaying bunch of duplicate error message when I have multiple data
matching the condition in the LHS.
Or, if the first time the data matches the condition in the LHS, then do
the RHS then stop
Is there anyway to do either 1 of those above? Thank you!

check dups
by Tim.Nguyen＠expeditors.com
Hi List,
I'd like to check if any duplicate exists in my collection as below:
rule "check Duplicate"
when
ref1: Reference ($type1: referenceType, $value1:
referenceValue)
ref2: Reference (this != ref1, referenceType == $referenceType,
referenceValue == $value1)
then
errorHandler.record("Duplicate Reference is not allowed.");
end
Both my referenceType and referenceValue are String. I didn't get any error
but it didn't work. Any idea?
I am using 4.01 GA
Thanks,
Tim
