ksession persistence (from docs) - not getting it to work
by amarok
I try to persist a knowledge session using the example code from Drools
5.5.0-Final Documentation. And I am stuck with following exception:
javax.persistence.PersistenceException: [PersistenceUnit:
org.drools.persistence.jpa] Unable to build EntityManagerFactory

Probably I did some configuration mistake. This is my setup:
1) I added following dependencies (via maven)
drools-persistence-jpa, btm (bitronix), h2 (database),
hibernate-entitymanager
2) I created a hibernate.cfg.xml, persistence.xml and jndi.properties file
(I put the jndi.properties file in resources/META-INF ( is this correct/
related to the error ?))
3) I made all my fact classes serializable
4) I added this code:
PoolingDataSource ds = new PoolingDataSource();
ds.setUniqueName( "jdbc/BitronixJTADataSource" );
ds.setClassName( "org.h2.jdbcx.JdbcDataSource" );
ds.setMaxPoolSize( 3 );
ds.setAllowLocalTransactions( true );
ds.getDriverProperties().put( "user", "sa" );
ds.getDriverProperties().put( "password", "sasa" );
ds.getDriverProperties().put( "URL", "jdbc:h2:mem:mydb" );
ds.init();
org.drools.runtime.Environment env =
KnowledgeBaseFactory.newEnvironment();
EntityManagerFactory emf =
Persistence.createEntityManagerFactory("org.drools.persistence.jpa");
env.set(EnvironmentName.ENTITY_MANAGER_FACTORY, emf);
env.set(EnvironmentName.TRANSACTION_MANAGER,
TransactionManagerServices.getTransactionManager());
env.set(EnvironmentName.GLOBALS, new MapGlobalResolver());
StatefulKnowledgeSession ksession =
JPAKnowledgeService.newStatefulKnowledgeSession(kbase, null, env);
This is my Hibernate config:
<!DOCTYPE hibernate-configuration PUBLIC "-//Hibernate/Hibernate

"http://hibernate.sourceforge.net/hibernate-configuration-3.0.dtd">

Not able to fetch values from a list in Guvnor web based decision table
by ashish6276
Hi All,
I have a request with /market/ which is a list of /market info/ something
like this :
*<complexType name="RuleRequest">
<sequence>
<element name="Market" type="tns:MarketInfo" maxOccurs="unbounded" />
</sequence>
</complexType>
<complexType name="MarketInfo">
<sequence>
<element name="region" type="String">
</element>
<element name="country" type="String">
</element>
</sequence>
</complexType>*
While writing DRL like this I am able to fire the rules:
*when
hotelReq : HotelRequest ($market : market != null )
MarketInfo( region == "NA") from $market
then
System.out.println("Done");
end*
But am not able to achieve the same thing in web guided editor in
Guvnor(Decision table).
I came close enough to write the below in web based editor but could not
succeed in firing the rules.
*when
hotelRequest : HotelRequest( $market : market != null )
marketInfo : MarketInfo( region == "NA" ) from entry-point
"$market"
then*
Any help will be appreciated.
Thanks in advance.

Fusion 5.5 - Deterministically identifying event insert order?
by dunnlow
I am testing with fusion (5.5) and running into an /intermittent /issue. I
am trying to track transitions between two big events (BEvent) using a
smaller event (SEvents) with the properties I care about. The idea is that
I will maintain many SEvents in memory for the different kinds of BEvents.
My basic steps (partly driven by salience) are:
1) rule a: (salience=100): when a new BEvent is inserted, insert a new
related SEvent
2) rule b: (salience=50): If there are two SEvents for this type of BEvent,
compare them (old vs new) and act accordingly
3) rule c: (salience=0) remove the *old* SEvent (keeping the latest one)
4) rule d: (salience=-50) retract the BEvent
My rule c (above) is:
when $se1 : SEvent(name matches "auto")
$se2 : SEvent(this after $se1, style matches ($se1.style))
then
retract($se1);
end;
I am of course running in stream mode and this USUALLY works, but sometimes
rule c does not get activated - based on the audit log. Also, I have a
DebugWorkingMemoryEventListener configured and I can see that two SEvents DO
exist in working memory which should activate it.
In my test, I have a loop in which I am inserting events. When I add a
brief delay, I have not seen a failure. My guess is that the timestamps on
the two events are the same, thus the "after" is causing the issue.
However, I am unable to test this as the timestamp on the event is not
accessible (from what I have found on this forum).
I saw a suggestion here about using a variable on my SEvent to tell the
difference between a new and old version. I also considered using some sort
of counter bean to order the SEvents (although I believe it would need to be
serialized).
My questions:
1) Do you agree with my assessment? Is it possible in stream mode to have
two events with the same timestamp?
2) what is the BEST way to identify which event was inserted first?
Thanks for any insight!

Reg : Drools 5.5 Templates : CompoundValueRestrictions
by Barada (Native5)
Hi,
Am trying to model some rules using drools templates.
Currently the data inputs to rule templates are only strings, I need to be able to define a compound value restriction set for the rule i.e if fact attribute is present in a list. (see sample below).
e.g.
template header
dealers
template "my-template"
rule "my-rule"
when
$order : Order(dealer in (@{dealers}))
then
System.out.println("Order is present in dealer"
end
end template
I am trying to compile this template by passing it an Object which has a dealers attribute which is essentially a List<String>. Short of creating a function which sends back a comma separated representation of the list, does the drools compiler provide any option to send a list.

NullPointer while deleting a rule since 6.0.0 upgrade

Does Guvnor limits the number of unsuccessful Login Attempts ?
by Zahid Ahmed
Hi,
I want to know that is there any configuration in Guvnor to limit the number of unsuccessful login attempts. This is required as I want to prevent Brute Force attack on my production Guvnor server.
Environment:
1. Drools-Guvnor 5.5.0-Final
2. Jboss EAP 6.1.0
Thanks and Best Regards,
Zahid Ahmed
