Re: [rules-users] Drools firing wrong rules
It's indeed a bug - a regression from 5.1.1. Depending on the fact classes coming from Java or their being declared in DRL, different error scenarios can be reproduced - see JBRULES-3129 and JBRULES-3130, the latter being the issue reported by pamerida. @pamerida: With 5.2.0, the only workaround that appears to cover all contigencies is to give the mvel-ish expression a wide berth and use eval( ((Three)list.get(0)).getA() == null ) On 12 July 2011 01:37, pamerida elp...@hotmail.com wrote: Hi.. sorry I didnt include all the information... heres the class Im using http://drools.46999.n3.nabble.com/file/n3160827/ruleInvoker.java ruleInvoker.java I use the method invocarReglas...

[rules-users] Drools and serialize
Hi,
I want to serialize a StatefulKnowledgeSession in drools (which have rule
and fact)
Actually i know how to serialize a KnowledgeBase.
Here is my code for serialize a KnowledgeBase:
KnowledgeBuilder kBuilder =
KnowledgeBuilderFactory.newKnowledgeBuilder();
kBuilder.add( ResourceFactory.newFileResource( Sample.drl ),
ResourceType.DRL );
if( kBuilder.hasErrors() ){
for( KnowledgeBuilderError err: kBuilder.getErrors() ){
System.err.println( err.toString() );
}
throw new IllegalStateException( DRL errors );
}
KnowledgeBase kBase = KnowledgeBaseFactory.newKnowledgeBase();
kBase.addKnowledgePackages( kBuilder.getKnowledgePackages() );
OutputStream os = new FileOutputStream( droolsCompiledFile );
ObjectOutputStream oos = new ObjectOutputStream( os );
oos.writeObject( kBase );
oos.close();
This work fine, no problem here.
Here is my code for serialize a StatefulKnowledgeSession:
KnowledgeBuilder kBuilder = KnowledgeBuilderFactory.newKnowledgeBuilder();
kBuilder.add( ResourceFactory.newFileResource( Sample.drl ),
ResourceType.DRL );
if( kBuilder.hasErrors() ){
for( KnowledgeBuilderError err: kBuilder.getErrors() ){
System.err.println( err.toString() );
}
throw new IllegalStateException( DRL errors );
}
KnowledgeBase kBase = KnowledgeBaseFactory.newKnowledgeBase();
kBase.addKnowledgePackages( kBuilder.getKnowledgePackages() );
try {
KnowledgeBase kbase = readKnowledgeBase();
StatefulKnowledgeSession ksession =
kbase.newStatefulKnowledgeSession();
Message message = new Message();
message.setMessage(Hello World);
message.setStatus(Message.HELLO);
ksession.insert(message);
Marshaller marshaller = MarshallerFactory.newMarshaller(
ksession.getKnowledgeBase(), new ObjectMarshallingStrategy[]{
MarshallerFactory.newSerializeMarshallingStrategy() } );
ByteArrayOutputStream baos = new
ByteArrayOutputStream();
ObjectMarshallingStrategy oms =
MarshallerFactory.newIdentityMarshallingStrategy();
marshaller.marshall( baos, ksession );
ObjectOutputStream out = new ObjectOutputStream( baos );
out.writeObject( marshaller );
out.close();
baos.close();
ksession.fireAllRules();
} catch (Throwable t) {
t.printStackTrace();
}
}
But this didn't work.
I get always the same error:
java.io.NotSerializableException
I have try to not implement the marshall but this didn't work.
I don't know what I must do. Can someone help me?
Thank.

Clement Pernot

Re: [rules-users] Starting Guvnor in Eclipse
Thank you, I had to remove completely the test directories from the project because once in the project I couldn't unselect them anymore from the launch configuration. Now the errors are gone, cool :) I just hope I won't need test back. With the abysmal startup speed I guess I have to learn to live - I had FastCompiledGuvnor also before. It's almost as slow as JBoss 6...

What you need to do is manually delete all references to test resources in the launch configuration classpath. The apparant lock-up is GWT compliling JScript from the Java code. It can be made quicker by:- * Ensuring no test resources are on the lanch configuration (which will also remove the errors) * Using the FastCompiledGuvnor module (which only compiles for en_US and Firefox - gecko1_8). ___ rules-users mailing list rules-users@lists.jboss.org https://lists.jboss.org/mailman/listinfo/rules-users

Haven't used this before, but looks like DefaultMarshaller is not serializable.

Re: [rules-users] Drools and serialize
You call
ObjectOutputStream out = new ObjectOutputStream( baos );
out.writeObject( marshaller );
which would (if it succeeded) just serialize the MarshallerImpl, which is
useless as it is nothing but the ballpen with which you write. You need to
serialize the text via a call to
marshaller.marshall(...)
as you do. But, to really get it on paper, you must write to a file. Using
FileOutputStream might be an option.

Re: [rules-users] Drools and serialize
This looks wrong to me
ByteArrayOutputStream baos = new ByteArrayOutputStream();
Marshaller marshaller = MarshallerFactory.newMarshaller(
ksession.getKnowledgeBase(), new ObjectMarshallingStrategy[]{ oms } );
marshaller.marshall( baos, ksession );
ObjectOutputStream out = new ObjectOutputStream( baos );
out.writeObject( marshaller );
out.close();
Presumably the marshaller is writing out the knowledge session to the output
stream, then you are trying to use an object output stream to output the
marshaller you just used.
I think in this case you need to use one or the other - either just write out
the knowledgebase through the objectOutputStream, or write out the knowledge
base with a custom marshaling strategy with the Marshaller, not both!

Hi,
Below are 2 rules, rule1 has higher precedence than rule2. Rule2 should not
execute if Rule 1 executes.
1) One way to get this working is to check the null value.
2) If the update is not called, the Rule2 gets executed using the previous
null value of potentialTheftRating.
Is there any other way to implement this requirement.
rule Rule 1 PotentialTheft0 ruleflow-group TheftRating0

Re: [rules-users] Drools and serialize
You don't need the object output stream below - and it's very bad code to give
access to the same output stream to two parents (the marshaller and the OOS in
this case) as you can end up just writing garbage if they interleave their
writes - you don't know the buffering policy that each parent is using.

Re: [rules-users] repository in 5.2.M2 crashes in 5.2.Final because of decision table serialization
That explains it. The CEP changes were made between 5.2.M2 and Final. Since 5.2.M2 was a beta Mark Proctor was OK not keeping backwards compatibility between the M2 and Final. I checked before making the changes. Unfortunately the code-base only supports automatic conversion between 5.1.Final and 5.2.Final. Any guided decision tables made on 5.2.M1, 5.2.M2 and 5.2.CR1 are incompatible with 5.2.Final.

Is this XLS decision tables or in Guvnor? In Guvnor, if a condition uses either the == or != operator you can use the otherwise special value that achieves what you're looking for. It isn't possible with XLS at present, although there is a JIRA for the change.

[rules-users] how to eval with property inside a nested object
Hi everyone. I have a BaseProduct with paymentMode as a property BaseProduct is assigned to a Customer Customer creates a uProduct. uProduct is a customized product created by the customer. It contains multiple BaseProducts. for eg Music is a Baseproduct with Wire paymentMode Picture is a product with CreditCard paymentMode Movie is a product with DebitCard paymentMode iPod is a uProduct which contains Music and Pictures implies that it supports Wire and CreditCard iPad is a uProduct with contains Music, Movies and Pictures implies that it supports all paymentModes rule Non Mandatory // calculates all non mandatory fields for display when $transaction : Transaction($paymentModes :uProduct.baseProduct) // select all the paymentModes supported by the uProduct $displayMode : Property(payMode in $paymentModes) // select a property which has a valid paymentMode ... someOther conditions then ... in the above rule $paymentModes returns arrayList of baseProducts. But I want to access the list of paymentModes. ie, when Transaction has iPod $paymentMode should return [wire,CreditCard], when Transaction has iPad it should return [wire,CreditCard,DebitCard] Question : How do I access array of a selected property which are again part of Array of an object ? Any suggestion ?

Objects produced by a from clause that haven't been inserted into Working Memory previously are not facts, let alone events.

Frist, with from it isn't inserted at all, and second, if it were inserted, what timestamp would it receive - the time it was taken from session.getUserByIndex(0)?

Re: [rules-users] Temporal reasoning with external persistence not working
First of all, don't use automated time stamping of events; add a field carrying the (original) event time. I think you could also run the session in CLOUD mode. Also, it may not be advisable to pull in facts and reason over them in the same rule. Perhaps retrieval and proper insertion of facts should even be coded in Java, kept separate from the rule logic. Much depends on the required use cases for running those multiple sessions, and how canned events relate to other data. -W On 13 July 2011 02:13, rp2 amant...@gmail.com wrote: Wolfgang Laun-2 wrote: The example does not use events, as in @role(event).
