Two version of hibernate in the same classpath, how to specify thecorrect version to be used in drools ?
by JAMAL Moundir (EXT)
Hello,
I'm working on a new functionality of an existing project, we will use drools flow to manage our workflow and we want to use persistent and BAM capabilities given by drools.
In all the examples I saw on the internet, only hibernate is used as an implementation of JPA, so I made an example who work very well using hibernate.
The problem is that the existing application already use an old version of hibernate. I can't change it ! So I have two versions of the hibernate in the same classpath which's made several problems.
Maybe I can use another implementation of JPA with drools, but It will be difficult to change the persistence and the BAM from hibernate to another framework !
What I want to do, is to keep hibernate and tell drools to use a specific version of hibernate, I don't know how to do this ? maybe with using the manifest but I don't know if It will work !
Any idea
thanks

NPE in Drools JPA Persistence with rules that use Flow
by Shannon Hastings
I am using drools 5.2.0.M2 and I still get this error:
Caused by: java.lang.NullPointerException
at org.drools.marshalling.impl.InputMarshaller.readLeftTuple(InputMarshaller.java:469)
Which was reported on drools 5.1.0 JIRA and claimed to be fixed. I see the error when trying to load a session that was persisted that had objects inserted that are time depended and cause rules to fire that use terms from flow such as "after". I only see this error if create a new session, submit some facts to it, close it, and then try to reload. If i do not submit any facts to it I do not get the error. I.E. If all i do is create the KB with my rules I can reload a session from the DB no problem, but if i submit some facts and persist the session, then i cannot reload it. This seems to be an issue with the JPA loading of the session that has facts in it that use Flow (JBPM). Any help would be greatly appreciated. Below are my simple rules followed by the test code used to submit the facts:
package com.inventrio.rules.readings
import com.inventrio.healthmonitoring.model.*;
declare Reading
@role(event)
@timestamp(readingTime)
end
rule "High Blood Pressure"
when
$eventA : Reading(readingType.name == "BPMETER")
$systolic : Value( this.valueType.name == "SYSTOLIC" ) from $eventA.values
$diastolic : Value( this.valueType.name == "DIASTOLIC" ) from $eventA.values
eval( $systolic.getLongValue() > 180 && $diastolic.getLongValue() > 120 )
then
System.out.println("HIGH BLOOD PRESSURE" );
end
rule "Weight Trending Up"
when
$eventC : Reading(readingType.name == "WEIGHT" )
$eventB : Reading( readingType.name == "WEIGHT" , this after[5s, 1m] $eventC )
$eventA : Reading( readingType.name == "WEIGHT" , this after[5s, 1m] $eventB )
$weight3 : Value( this.valueType.name == "WEIGHT" ) from $eventC.values
$weight2 : Value( this.valueType.name == "WEIGHT" ) from $eventB.values
$weight1 : Value( this.valueType.name == "WEIGHT" ) from $eventA.values
eval( $weight3.getDoubleValue().doubleValue() < $weight2.getDoubleValue().doubleValue() + 1.0 && $weight2.getDoubleValue().doubleValue() < $weight1.getDoubleValue().doubleValue() + 1.0 )
then
System.out.println("WEIGHT IS GOING UP" );
end
rule "Weight Trending Down"
when
$eventC : Reading(readingType.name == "WEIGHT" )
$eventB : Reading( readingType.name == "WEIGHT" , this after[5s, 1m] $eventC )
$eventA : Reading( readingType.name == "WEIGHT" , this after[5s, 1m] $eventB )
$weight3 : Value( this.valueType.name == "WEIGHT" ) from $eventC.values
$weight2 : Value( this.valueType.name == "WEIGHT" ) from $eventB.values
$weight1 : Value( this.valueType.name == "WEIGHT" ) from $eventA.values
eval( $weight3.getDoubleValue().doubleValue() > $weight2.getDoubleValue().doubleValue() + 1.0 && $weight2.getDoubleValue().doubleValue() > $weight1.getDoubleValue().doubleValue() + 1.0 )
then
System.out.println("WEIGHT IS GOING DOWN" );
end
And next is my object i insert before closeing and then trying to reload the session.
public void testWeightRules() {
try {
Reading reading = new Reading();
reading.setReadingTime(new Date(System.currentTimeMillis()));
ReadingType type = new ReadingType();
type.setName("WEIGHT");
type.setDescription("");
reading.setReadingType(type);
Value value = new Value();
value.setDoubleValue(140.0);
ValueType valueType = new ValueType();
valueType.setName("WEIGHT");
valueType.setDataType(ValueDataType.DOUBLE);
value.setValueType(valueType);
reading.getValues().add(value);
reading.setReadingType(type);
engine.process(reading);
Thread.sleep(7000);
reading = new Reading();
reading.setReadingTime(new Date(System.currentTimeMillis()));
type = new ReadingType();
type.setName("WEIGHT");
type.setDescription("");
reading.setReadingType(type);
value = new Value();
value.setDoubleValue(142.0);
valueType = new ValueType();
valueType.setName("WEIGHT");
valueType.setDataType(ValueDataType.DOUBLE);
value.setValueType(valueType);
reading.getValues().add(value);
reading.setReadingType(type);
engine.process(reading);
Thread.sleep(7000);
reading = new Reading();
reading.setReadingTime(new Date(System.currentTimeMillis()));
type = new ReadingType();
type.setName("WEIGHT");
type.setDescription("");
reading.setReadingType(type);
value = new Value();
value.setDoubleValue(144.0);
valueType = new ValueType();
valueType.setName("WEIGHT");
valueType.setDataType(ValueDataType.DOUBLE);
value.setValueType(valueType);
reading.getValues().add(value);
reading.setReadingType(type);
engine.process(reading);
} catch (Throwable t) {
t.printStackTrace();
}
}

Avoiding log or error messages on console
by Manuel Ortiz
Hi everybody:
I'm developing a Drools based application which has to show no messages on
console, but on log files or so. I've diverted these kind of messages to a
log file, but there is one at the beginning of the application, when the
change set is read...
(null: 6, 188): cvc-elt.1: Cannot find the declaration of element
'change-set'.
... which still appears on console.
I've read that this message doesn't affect rule engine behaviour, but I
would like it not to be shown on console.
Does anybody know how can I solve this problem?
Thank you in advance.
Best regards,
Manuel Ortiz.

Concatenating rule conditions
by Hezi Stern
I have a rule that filters an ArrayList based on dynamic filtering
conditions, for example this list can be a set of documents and the filter
can be a user property which is required later for document filling (e.g.
private name).
This is fairly strait forward, where I can perform something of the sort:
Rule "test filter"
When
$cm: ConditionMatrix(),
$document: ArrayList() from collect ( Document
(user.isPrivateName == $cm.isPrivateName) )
Then
//do something
End
Now comes my question: I have a different rule that holds a different set of
filter requirements that works on Document object.
For example
Rule "test filter 2"
When
$cm: ConditionMatrix(),
$document: ArrayList() from collect ( Document
(Payment.isLegal == $cm.isLegal) )
Then
//do something
End
Is there any way to combine them both?
Thanks
