Hi Mauricio
No I haven't seen that. Thanks for telling me this.

Thanks & Regards

drools-[slidingTimeCount]
by Francesco Chiarelli
Hi!
I'm trying to use a sliding time fro count a facts with a condition.
I'have set a stream mode.
In test, with pseudo clock active, set this to current Time (it's correct?),
declare a fact type in drl with
declare MyFact (i've a javabean)
@role(event)
@timestamp(myTimestamp)
end
attribute type of myTimestamp must be long or Date? I've tried with both but
nothing, engine count all fact
ex: n fact in x days ago from now, the statement over window:time(1s) result
always n fact. why?
in when:
// $o : Order(<condition>)
$nRic : Number(intValue<maxRic) from accumulate($n: Order(this==$o) over
window:time(1s),count($n))
ps. if i set a real clock altough a pseudo, in runTime i've a ClassCastExc.
to JdkTimerService
Thanks in advance.

drools-[SplitConstraint]
by Francesco Chiarelli
Hi!
In a split constraint i've:
$bool:Boolean(booleanValue==true) from hbnSession.createQuery("select active
from Euristic where name=:name").setString("name","C").uniqueResult()
eval($bool)
but the result is:
XOR split could not find at least one valid outgoing connection for split
C_isActive?
hbnSession is an active hibernateSession
In a simple drl rule, this works fine.
unfortunately, the previous post (slidingTime) is yet unresolved. :(
Thanks in advance.

DROOLS 4.0.7 Regular expression
by Romain Van der Keilen
Hi there,
I'm looking how to use regular expression with Drools 4.
I've already found some things but they don't work.
Here is an example I want to do, considering all getters and setters are properly written:
Class House
+ private Window myWindow
+ private Phone myPhone
Class Door
+ private String name
Class Phone
+ private String phoneNumber
Let's say in my country phone numbers are the following type: xx/xxx.xx.xx
If I give my house to the session, how can I check if the phone is correct? I've tryied this but that's not working:
rule "Check phone"
when
h : House ( phone: phone );
eval ( phone != null );
Phone ( phoneNumber matches "^ -regex- $");
then
System.out.println("my phone is correct");
End
Thanks for help,

Using constants in drools flow
by kothvandir kothvandir
Hello,
How can I define a constant in en jboss flow process so I can use it in a
flow-group rules?
I have defined it in the .drl that contains the ruleflow-group but when i
try to set the constant with my service object using:
ksession.setGlobal("myService", serviceObject);
an Exception is thrown
java.lang.RuntimeException: Unexpected global
[myService]
Is there any way to define globals in the .rf file within <head> tag? anyone
knows where can i find the xsd description for .tf files?
Thanks

Re: [rules-users] populating global variable in Condition Section?
by Greg Barton
Of course, I had to test that assertion. :)
$ java -Xmx128M -server -jar target/DroolsExistence-1.0.jar not.drl 50000
25000
2395ms
$ java -Xmx1024M -server -jar target/DroolsExistence-1.0.jar not_exists.drl 50000
25000
121378ms
You ain't kiddin'! 50x slower requiring 9x the memory.

BRMS configuration changes to support Oracle
by David Godfrey
Hi,
Is anyone able to supply an example repository.xml used to configure Drools
BRMS to work with an Oracle database rather than flat-file based repository?
I have tried following examples I found on the internet, including the
Jackrabbit site, but it is very non-obvious and there seems to be no example
showing a full working xml file, just small snippets.
With the configuration I have, I can see that tables are being created in my
database, but I get many different errors, e.g. complaining that the
repository ".lock" file is locked by another process, even though I thought
it shouldn't be using that file any longer in favour of Oracle.
Many thanks,
Dave
