Connection with Active Directory multiple organizational units
by G3
I am able to authenticate with Active Directory but with only a single
organizational unit but not with users of multiple organizational units
This is my organizational structure
+cn=test,cn=con
--+ou=Sample1
-----uid:user1,uid:user2
--+ou=Sample2
-----uid:user3,uid:user4
--+roles
-----admin:uid:user1,user3
-----user:uid:user2,user4
I have set the admin rights accordingly in Guvnor.
I am using Jboss Guvnor standalone 4.2.3 and I am trying to connect
multiple organizational units using JAAS
my login-config.xml

Drools 5 PseudoClock with StatelessKnowledgeSession
by Ben Scott
_______________________________________________________________________________________
Note: This e-mail is subject to the disclaimer contained at the bottom of this message.
_______________________________________________________________________________________
I'm wanting to use the date-effective and date-expiry rule metadata to add date specific rule variants within my app. To test these I was planning on using the pseudo clock and setting the expected date prior to executing the rules within a StatelessKnowledgeSession. I can set the clock easily enough, but can't understand why the getSessionClock() method is missing? It's on the StatefulKnowledgeSession, but not on the Stateless.
I'm initialising the session like this:
SessionConfiguration sessionConfiguration = new SessionConfiguration();
sessionConfiguration.setClockType( ClockType.PSEUDO_CLOCK );
StatelessKnowledgeSession session = _testKnowledgeBase.newStatelessKnowledgeSession(sessionConfiguration);
The only thing I could think of to set the pseudo clock was to write a command something like:
private static class SetPseudoClockCommand implements org.drools.process.command.Command<Boolean> {
public Boolean execute(ReteooWorkingMemory session) {
// Set the clock to the current date
pseudoSessionClock.advanceTime(new DateTime().getMillis(), TimeUnit.MILLISECONDS);
// Add a couple of days
pseudoSessionClock.advanceTime(2, TimeUnit.DAYS);
return true;
}
}
But this doesn't appear to take any effect whilst rules are running.
Is there another way to get programmatic access to the session clock, or some better way of changing the underlying date prior to rule execution?
Ben.

Date validation in Guvnor
by mick00
Hi,
I want to validate the date format in my rule. I just want to check whether
my date is in the given format(yyyy-mm-dd) in my rule in Guvnor. Is it
possible to do such validation in Guvnor? I tried the same but got an
exception stating that the date is not in the given format(dd-MMM-yyyy). Can
someone suggest a solution as to how to validate the date in Guvnor?
Thanks,
mick

Fusion and open-ended intervals?
by Barry Kaplan
A fusion design question:
I have events that represent intervals. Initially the intervals are
open-ended (kind a like the current state of an entity). Other events are
matched "during" the interval and correlated. At some point the interval
will be closed (eg, a specific downtime interval is closed because the
device is no online again).
All the events in this system are immutable -- so if some property of an
event changes, it is cloned and modified in working-memory. For the case of
the interval events, initially the interval is inserted open-ended, and at
some point later closed and then modified.
This does not work with fusion however, since an event's duration is
maintained by the fact-handle not the event itself. Hence a modify with a
now closed interval (ie, a finite @duration) has no effect. I'm guessing the
temporal values are maintained the handle to ensure stable values for the
behaviors that trigger based on temporal values, which is reasonable.
So I'm looking for alternative designs. Some are:
1) Modeled the intervals as begin/end events, but that gets messy real
fast (have to correlate
the begin/end events somehow, can't use evaluators like 'includes' or
'during', etc).
2) Retract the interval event when it is closed (this way closed intervals
no longer correlate
with other incoming events). But then we really have a manually
maintained state machine
using only facts, and there can be no reasoning over a series these
interval events.
(eg, 3 downtimes longer than 2 minutes in the last hour).
Opinions?

Persistence of events
by Maciej Prochniak
Hello,
Is it possible to persist events (from drools fusion) with default jpa
mechanism? When I try to do this 'just like that' I get exception
like
org.drools.common.DefaultFactHandle incompatible with
org.drools.common.EventFactHandle
It seems that session marshaller is not really aware of certain objects
being events, not facts.
The code I try is more or less like:
UserTransaction ut = ...
StatefulKnowledgeSession session = JPAKnowledgeService
.newStatefulKnowledgeSession(kbase, null, env);
ut.begin()
session.insert(e1);
ut.commit();
StatefulKnowledgeSession sessionPersisted =
JPAKnowledgeService.loadStatefulKnowledgeSession( session.getId(),
kbase, null, env );
ut.begin()
sessionPersisted.insert(e2); (*) <- fails
ut.commit();
When I use session instead of sessionPersisted - it works fine, when
e2 is a fact, not an event - it also works
I know that it may be awkward to persist events which have time
limitations, but I want to use time limits in rules which are like few
days - so I want to have some persistence in case of server shutdown.
I would be grateful for any comment,
br,

Drools-Fusion : Inserting an Event in to an "entry-point" stream in the RHS of a rule?? Pls help
by Chetan Mahadev
Hi
Can we insert an Event in the RHS part of a rule to an entry-point?
basically i am trying to do this. Pls let me know if this is possible? if
not any alternative approaches? Any example would be useful pls
declare TransactionEvent
@role( event )
end
$tmp : TestClass()
$tmp.message == "TRUE"
then
TransactionEvent ev1 = new TransactionEvent (); // This should be
inserted in to an entry-pont "Temporal Reasoning" stream
ev1.setMessage("Temporal Reasoning")
insert (ev1) to entry-point "Temporal Reasoning"
end
rule "Temporal Reasoning"
$tmp : TransactionEvent ( message== "Temporal Reasoning") from entry-point
"Temporal Reasoning"
then
System.out.println("Rule fired due to entry point ");
end

unable to determine operator for symbol [before]
by vladimiro
Hi all,
I'm building a KnowledgeBase with KnowledgeAgent and a precompiled
rule package. When the package contains a rule using temporal operators
such "after" or "before" I get the exception listed at the end of this
message.
I'm using the latest version of drools 5 and my runtime configuration
includes the following libraries:
* drools-core - the rule engine itself.
* drools-api
* mvel2-2.0.10
* joda-time-1.6
the rule causing such a behaviour is:
rule 'Test2'
dialect 'mvel'
when
u1:UserType( firstName=="UserA" )
lie:UserEventType( event=="Login", user.id==u1.id)
loe:UserEventType(event=="Logout", user.id==u1.id, this before lie)
then
Message msg = new Message();msg.setText("Test2
fired");driver.getMessages().add(msg);
end
