Hello, forget date-expires. Just make your WHEN condition to match
date you specify somewhere in your object as date for which to
calculate. Then you will have two rules and each will match different
date.

In default setup of many servers (which I know) and java has no
prohibited reading of files outside ear. You can read changeset and
rule files from specific directory e.g. (/etc/rules/...). Or you can
use user.home property. We are using it without problems.
However you can use other mechanisms whi
You can do it with singleton pattern. File should be read with something like:
ResourceFactory.newClassPathResource("/MyChangeSet.xml")
RuleAgent monitor all resources which are described in change-set.
Changes of change-set file aren't reflected.

Don't know details of your problem but it's typical situation where
you can use StatelessSession, insert one fact at time and use
activation-group.

You described it well. Did you tried it? It should work. Doesn't
matter where are you connected (local JVM or remote JVM). Debugging
should work same way.

Just look to Properties documentation. You can set property from java
too. Something like:
Properties properties = new Properties();
properties.load(new FileInputStream(module2PropertiesFilePath));
properties.setProperty("url", "http://MyURL...";)
RuleAgent agent = RuleAgent.newRuleAgent(properties
But you don't need autorization details.

I will do following:
- Create package for each user (with same name as user) - and restrict
access only for specific user

But for this you don't need drools flow. Normal rule-set is enough.

Another "simple" way will be to declare global variable like:
global List EBandRating;
and in then clause you can do:
EBandRating.add(r);
You don't have to make queries, no-loops, lock-on-active or other tricky stuff.

Aha, misunderstanding. Yes you can't use activation group if you want
execute more children rules. However you can use fact (Status) to
avoid evaluating parent rule. My suggestion:
Rule DEFAULT
salience -100
if A and ! Status(done) then DEFAULT end
Rule A
if A and B then SOMETHINGB; update(Status
Sorry don't watch thread in detail but something like this should be
achieved by defining "salience" on rule. Usually you define same
condition withing same activation group with e.g. salience -100 which
will fire as "default" when nothing match.
But maybe I'm totally out of scope

It's like synchronous vs. asynchronous communication. In reality it's
always asynchronous but from top view it appear synchronous.
Similar to stateless vs. statefull. Statefull is just series of
stateless session where you transfer state from one session to
another. Look for Drools statefull persis
How was suggested before (in other thread) you can:
1) use getTime() method of Date class which return "long" and compare
2) use some good library for example Joda time with eval()

At first start with tuning JVM. Xms, Xmx parameters. How much physical

I just read you condition. You are building $endDate to
Segment.endDate and than comparing Segment.startDate with $endDate
what is same as comparing Segment.startDate with Segment.endDate ->
transition principle.

What about:

Segment ($endDate : endDate, startDate < $regDate || startDate > endDate )
Logically startDate > endDate doesn't make sense but it should work ;-)

Try to do this in bank application. People come 1 hour after they date
expired and try to charge them for sooner withdrawal because you
calculate with 365.25 not 365 days. You will be kicked, believe me.

I will show you our approach. We have rules in rule base like:
rule "start calculate"
when
RULE TO START CALCULATION
than
insert(new CalculateFee("firstFee,secondFee".split(",")))
end
rule "END calculate"
salience -100
when
RULE TO START CALCULATION
$fee:CalculateFee()
than
CALCU
Maybe here is some complex support for this but if you use ruleflows
than it's complicated however what about (noob idea):
rule "first - only once"
when
not RuleXor( name == "first")
...
than
insert (new RuleXor("first"));
end

Hello,
I would like to calculate AGE of object based on Date inside object, I
can use eval but I hope it's so basic functionality that Drools should
have it. It's also performance problem if I need to use EVAL in many
rules (let's say 100 in XLS). I'm playing with some FUSION features
like:
$n
39 matches
