Basically, yes. The update statement should be used to indicate that an object has changed. Using it for other purposes is of course possible, but I'd avoid it unless there was good reason.
See the attached sample project. Is this what you're doing? I put in a rule that checks the value of an object that is modified externally:
rule "Conditional Match"
when
c : Cycle()
d : Data( value < 5 )
then
System.out.println( "Conditional Match: " + c + " with " + d );
end
Works fine.

need help on java.lang.NoClassDefFoundError: org/drools/lang/DRLParser
by aMin kAmiL
Hello everyone,
I am new to Drools and has been working and studying on it for the past 3
weeks. I'm currently working on a project using JBoss Seam and WebLogic (I'm
new to these technologies also), and there are quite number of rules that
need to be implemented to the system. Below is the stack trace after I
clicked on an action button from the UI that will trigger the rule action:

I've been trying to solve this issues since a few days back. However I
couldn't find the solution.
It worked fine previously until I updated my project folder from the cvs.
I'm afraid that there could be any missing jars.
Hope anyone could help me.
Thank you very much.

Trying to bring Drools up in Weblogic 9.2
by Mulcahy, Lawrence
Anyone know what's wrong here?
I'm trying to deploy Drools Guvnor 5.0 into Weblogic Server 9.2 MP2.
Java runtime is (64 bit)
java version "1.5.0_14"
Java(TM) 2 Runtime Environment, Standard Edition (build 1.5.0_14-b03)
BEA JRockit(R) (build R27.5.0-110-94909-1.5.0_14-20080204-1536-solaris-sparcv9, compiled mode)
The first time I tried this it deployed successfully but when I tried
to surf to the Guvnor home page I got this error:
java.lang.NoClassDefFoundError: javax/faces/convert/ConverterException

Next I tried following the instructions at
http://firstpartners.net/kb/index.php/Deploying_JBoss_Drools_BRMS_on_Webl...
I extracted these files from myfaces and JBoss AS as described and
installed them in the lib directory of the Weblogic domain:
commons-beanutils-1.7.0.jar
commons-codec-1.3.jar
commons-collections-3.2.jar
commons-digester-1.8.jar
commons-discovery-0.4.jar
commons-logging-1.1.1.jar
jstl.jar
myfaces-api-1.2.7.jar
myfaces-impl-1.2.7.jar
serializer.jar
xalan.jar
xercesImpl.jar
As I tried to deploy drools-guvnor.war, it got a long stack trace starting with
java.lang.RuntimeException: Could not create Component: org.jboss.seam.web.exceptionFilter
Full stack trace follows:

Issue with Drools classloader in IBM Websphere (Drools 5.0)
by Pardha Neelisetty
Hi
I am getting the AccessControlException while deploying the drools in IBM
websphere 6.1. We have very restricted environment, can't provide
permission for *createClassLoader. *
Does Any body faced the similar issue ? and, any solution for this issue.
Thanks in Advance.
Pls. find the error stack trace.

Drools Fusion speedup
by PF
Hi guys,
We made some experiments with Drools Fusion and we wonder if there is any
way to speed it up. In our experiments, we detected complex events in
streams of stock tickers and got times significantly slower with Drools than
with other CEP systems (and also higher memory consumption in the same order
of magnitude):
Number of events Drools 5.0 Fusion Esper 3.1.0 Etalis with SWI Prolog Etalis
with Yap Prolog
10000 1179 453 328 265 (time in miliseconds to process the stream of events)
20000 2359 828 701 531
30000 3538 1141 1023 780
40000 4718 1500 1356 1078
50000 5897 1813 1702 1329
I can provide some of our code if someone needs it (beside what I pasted
below).
Please tell me if you know any obvious optimizations? Or if you think this
is due to Java (vs. C in other implementations), or any other reasons.
Thank you, regards,
Paul Fodor
Our program has 5 rules to detect complex events:
fusion.drl:
rule "experiment A -Rule 0/0"
when
$ae1 :Event(symbol == 1, $Pr1 : price) and
$ce1 :Event(this after $ae1 , symbol == 1, price > ($Pr1/1.2) )
then
//System.out.println("Ce1 fired !");
end
rule "experiment A -Rule 0/1"
when
(
$ae2 :Event(symbol == 2,$Pr2 : price) and

end
We have an Event class for events with its parameters and an EventStream
class to fire the events:
EventStream.java:
...
import org.drools.runtime.StatefulKnowledgeSession;
public class EventStream {
public StatefulKnowledgeSession get_working_session() { return ksession;}
...
void generateEventStream(double duration, double p) {
...
//Drools
Event temp = new Event(symbol,currValue);
ksession.insert(temp);
...
}
}

infinite loops with "no-loop true"
by Nord, James
Hi all,
It seems to me that the no-loop only prevents a rule from triggering
itself - and doesn't make the rule only fire once (which is what I'm
after)
e.g. consider the following two contrived simple rules:
rule "addPriorityPrefix"
dialect "java"
no-loop true
when
$work : Work (priority >= 200)
then
modify($work) {
setTitle("!!! " + getTitle());
};
end
rule "re-assign low priority tasks"
dialect "java"
no-loop true
when
$work : Work (priority < -200)
then
modify($work) {
setOwner("nobody");
};
end
What I end up with is an infinte loop.
Whilst for the simple case I can re-write them like
$work : Work (priority >= 200, !title.startWith("!!!"))
however with the more complex rules this makes the rules get very
complex quickly and less easy to write. Is there a way to prevent these
loops - have I misunderstood or do you really need to check everything
in the rule that you may set?
How would you do the banking interest example?
rule "interest calculation"
no-loop
when
$account : Account( )
then
modify($account) {
setBalance((long)($account.getBalance() * 1.01) )
};
end
if there was another rule that if you where a gold customer and payed in
> $500 the previous month then you get $4 bonus?
rule "gold bonus"
no-loop
when
$account : Account(type="gold", previousMonthDeposit > 500 )
then
modify($account) {
setBalance((long)($account.getBalance() + 4) )
};
end
Regards,
/James

3rd Event-driven Business Process Management Workshop (3rd edBPM '09) at CASCON 2009 - Call for Participation

CALL FOR PARTICIPATION
3rd Event-driven Business Process Management Workshop (3rd edBPM '09)
at CASCON 2009
November 3rd 2009, Toronto, Canada
https://www-927.ibm.com/ibm/cas/cascon/displayWorkshop?PublicView=true&Num=5

"Event-Driven Business Process Management" (EDBPM) refers to an enhancement
of traditional BPM through novel combinations of Service Oriented
Architectures (SOA), Event Driven Architectures (EDA), Software as a Service
(SaaS), Business Activity Monitoring (BAM) and the Processing of Complex
Events (CEP). BPM in turn, refers to a software platform which provides
companies and end-users the ability to model, manage and optimize business
processes.
This workshop introduces the state-of-art concepts underlying EDBPM
solutions, summarize standard best practices in event management, and
discusses the shortcomings, challenges and obstacles. Specifically, there
has been little understanding of service impact beyond event severity and
root-cause of business events. This brought attention to more sophisticated
correlation mechanisms and infrastructure to reason about dependency between
events and their sources. Also, we discuss the various methods of mapping
event incidents to customer SLA and KPI that are crucial for identifying any
escalating problems critical to the business.

loading rules from database
by Abarna Ramachandran
*Hi
Please help me making a decision regarding loading rules from database.
*1. How to* *programatically inject the rules into rule engine using drools
API. ? (i cant find any drools API to load into Knowledgebuilder as
rulesCondition,rulesConsequence etc. Should i create my own API? )
2. Which is better approach ?
The above method (1.) or creating a drl using templates and data from
database and then injecting into Knowledgebuilder.
Please help me with this.
3. How to serialize the rulebase and use it later at runtime?
thanks

I think the better approach if possible is to serialize your rule base and
storing it in the database as such. Storing the DRL and recompiling your
rules at run time will be quite expensive. We have a similar setup and it
has worked out pretty well for us.

Hi,
If the rules,conditions,consequences have to be loaded from the database. I
can think of following two approach. what would be right approach( I will
have upto 1200 rules in the db)
1. Programmatically inject the rules into rule engine using drools API.
2. Read the rules from the database and create drl or dsl file for them and
inject into rule engine.
Thanks
