Hibernate Query delivers wrong values
by Thomas Zwifl
Hi there!
I'm working with the latest snapshot-releas of v5.1 (build3098-rev27324-20090630-0403).
My application consists of two independent processes,
both are repeated periodically (timer-node).
the processes both have ruleset-nodes. some rules are
querying a database with hibernate in the rule condition (LHS).
the queried objects are then inserted into workinmemory (insert(object)),
then some computation follows, the objects are modified and written
back to db, and then the objects are retracted (retract(object)).
Now to the problem: when I start the application, everything works
correct, and leads to the right results. But when I change a field of a
db-record manually, the hibernate-query delivers the old values!!
(of course the changes are committed.)
Anyone has an idea whats going wrong here? Is there some kind of
caching mechanism that delivers the old objects instead of querying
the database?
greetz!

How to iterate ArrayList object
by Ashok Deivasigamani
I have a Message Object which has a Attribute Object which has a ArrayList
of AttributeParams Objects. How can I iterate through the ArrayList to get
to a perticular AttributeParans Object in the drl file.
The java representation of these Objects are as Follows
Class Message {
private Attributes attributes;
}
Class Attributes {
private ArrayList<AttributeParams> attributeParams;
}
Class AttributeParsms {
private String name;
}
This is my drl file,
when
m : Message( myAttributes : attributes)
then
System.out.println(myAttributes);
System.out.println(myAttributes.getAttributeParams());
System.out.println( myMessage );
when I fire my rule, this is the output I am getting.
com.sample.Attributes@39c639c6
[com.sample.AttributeParams@39a639a6, com.sample.AttributeParams@39ac39ac]
>From the result we can see that we have two Attribute objects in the
ArrayList.

Detect changes in rules at runtime
by rviswanathan
Hi
I am using Guvnor for editing my business rules. I am able to write a test
program in java that would fire one sample rule that I have created in
guvnor.
public static final void main(String[] args) {
try {
// load up the knowledge base
//KnowledgeBase kbase = readKnowledgeBase();
KnowledgeAgent kagent = KnowledgeAgentFactory.newKnowledgeAgent( "MyAgent"
);
kagent.applyChangeSet(
ResourceFactory.newFileResource("C:/Test/changeset.xml"));
KnowledgeBase kbase1 = kagent.getKnowledgeBase();
StatefulKnowledgeSession ksession =
kbase1.newStatefulKnowledgeSession();
Message message = new Message();
message.setMessage("Hello World");
message.setStatus(Message.HELLO);
ksession.insert(message);
ksession.fireAllRules();
ksession.dispose();
}
catch (Exception ex) {
ex.printStackTrace();
}
}
Now I am trying to see if I would be able to detect changes in the rules
that I edit in Guvnor at runtime. What I am trying to do is to edit one of
the rules and save it, and I need this change to be picked up automatically
by my java application.
Is this possible? How do I do this?
Thanks
Ram

How work the sliding windows?
by linolia83
Hi all, I’m trying to build the example 2.14 in Drools Fusion at follow
link:
http://downloads.jboss.com/drools/docs/5.0.1.26597.FINAL/drools-fusion/ht...
two notes:
• Important: Sliding Windows are only available when running the engine in
STREAM mod (paragraph 2.6 – Sliding window )
• Drools generalized the concept of a stream as an "entry point" into the
engine. An entry point is for drools a gate from which facts come. The facts
may be regular facts or special facts like events. (paragraph 2.3 - Stream
support )
1) Presupposing that the SensorReading object is an event, why in order to
develop the example 2.14 the SensorReading object it didn’t use a
entrypoint? I have developed it in this way:
my regoleStream.drl file rule:
declare SensorReading
@role( event )
@timestamp ( timestamp )
@duration ( timeduration )
end
rule "Alarm"
when
TemperatureThreshold( $max : max )
$lettore: SensorReading( ) from entry-point "entry"
$media: Number( doubleValue >= $max ) from accumulate(
SensorReading( $temp : temperature )
over window:time( 5s ) from entry-point "entry" ,
average( $temp ) )
then
System.err.println("Temp media: " + $media);
end
I have defined my class SensorReading.java and Sensor.java
public class SensorReading {
private double temperature;
private long timestamp;
private long timeduration;
// constructor, getters, setters...
}
public class Sensor {
private Random random = new Random();
public double nextReading() {
return (20.5 + random.nextGaussian());
}
}
my class: DroolsTest is defined in STREAM MODE and PSEUDO CLOCK SESSION
configuration
(see the file DroolsTest.java)
http://www.nabble.com/file/p24406682/exampleSensorReading.zip
exampleSensorReading.zip
I have another question: using the accumulated function in order to
calculate the average, I must use update or an insert for a new reading? in
other words:
entrypoint.update( eventhandle, reading ); or
entrypoint.insert(reading);
Using the statement insert my output it is:

Re: Unable to load dialect 'org.drools.rule.builder.dialect.java.JavaDialectConfiguration: (Pradeep Ruhil)
by Pardeep.Ruhil＠lntinfotech.com
Hi,
Thanks Mark for answering my query.
Now I have set all the jars file in the classpath, but still m getting the
same exception.
The exception is caused by : Null pointer exception.
I am not able to understand why it is giving me this exception, while in
the mailing list I didn't found anybody having this
problem.
This is my code snippet :
KnowledgeBuilderConfiguration config = KnowledgeBuilderFactory.
newKnowledgeBuilderConfiguration();
config.setProperty("drools.dialect.java.compiler", "ECLIPSE");
KnowledgeBuilder kbuilder =KnowledgeBuilderFactory.newKnowledgeBuilder(
config );
//KnowledgeBuilder kbuilder =
KnowledgeBuilderFactory.newKnowledgeBuilder();
kbuilder.add(ResourceFactory.newClassPathResource(
"shopingdiscount.drl"), ResourceType.DRL);
Am I missing anything that is to initialized , so that I can get through
this Null Pointer Exception.
Please help me to through of this situation. I am stuck in this.
Thanks & Regards
Pardeep Ruhil
