MVEL Expression causing NPE in MVEL optimizer
by womuji
Hi,
I kept getting NPE for the following MVEL express in Drools rule:
---------------------------------------
rule "my Rule"
ruleflow-group "myGroup"
no-loop true
when
not Field(id=="meetingNotes")
$student : Student()
$homeAddress : Address() from
addressManager.findFirstAddressByTypeByPerson( new ReferenceCode("xyz"),
$student )
then
eventFields.put("meetingNotes",new
Field("meetingNotes",AbstractFieldConverter.formatFullAddress($homeAddress)));
end
---------------------------------------
the stack trace is:
---------------------------------------
[Error: null pointer: addressManager.findFirstAddressByTypeByPerson( new
ReferenceCode("xyz"), $student )]
[Near : {... addressManager.findFirstAddres ....}]

I'm using Drools5.3.0.Final, which in turn depends on MVEL2.1.0
Anything wrong with my MVEL expression?
Thanks in advance.

This is often caused by having a class defined at multiple
locations within the classloader hierarchy. Other potential causes
include compiling against an older or newer version of the class
that has an incompatible method signature.

Re: [rules-users] Loop Drools on Multi Element
by FrankVhh
Actually, I think that laune's solution is preferable as it should be a bit
more understandable.
Basically the rule states
If
An order is not high priority
And
There is no item with a quantity <= 2 in that order (Meaning, all items in
the order have a quantity > 2)
Then
Set prioiry of order to high
The main difference between his rule and your rule would be that you would
have to access quantity via your nested objects, while laune assumed it to
be accessible directly.
As for the example of forall, I never tried it with a list. Maybe I'll do it
later today. I would suggest you try it the laune-way.
Regards,
Frank

Guvnor pojo & InitialConext
by gombasp
Hello,
i tried to create a pojo and load it to Guvnor which would call an EJB on
the same Jboss AS 7.1.
Below code works in another app without problem.
public class Calculation implements IFCalculation {
IFRemoteCalculation remoteCalculation;
public Calculation() {
final String jndiName =
"java:global/remoteejb/CalculationBean!com.gp.IFRemoteCalculation";
try {
Properties env = new Properties();
env.put(Context.INITIAL_CONTEXT_FACTORY,
"org.jboss.as.naming.InitialContextFactory");
env.put(Context.URL_PKG_PREFIXES,
"org.jboss.naming:org.jnp.interfaces");
env.put(Context.PROVIDER_URL, "jnp://localhost:1099");
Context ic = new InitialContext(env);
System.out.println("about to look up jndi name " + jndiName);
Object obj = ic.lookup(jndiName);
System.out.println("lookup returned " + obj);
remoteCalculation = (IFRemoteCalculation) obj;
} catch (NamingException e) {
System.out.println("Nem talatam meg a calculation beant! " + e);
}
}
public void add(String s, int faktor) {
remoteCalculation.add(s, faktor);
}
public String getItems() {
return remoteCalculation.getItems();
}
public void setItems() {
remoteCalculation.setItems();
}
}
When i load this as a POJO and try to use it in a Guvnor test scenario with
my rules i get following error:
12:47:17,673 ERROR [org.drools.guvnor.server.RepositoryAssetService]
(http--127.0.0.1-8080-5) Unable to run the scenario.: [Error: could not

It seems it is not possible to get InitialContext in a pojo uploaded to
Guvnor - or is there any way?

Not sure that I did it quite right...
by stephen.masters＠me.com
It seems that Guvnor bug 1507 was resolved as not reproducible. I came across it this morning and have attached a repo extract that demonstrates it.
However, I'm not able to re-open it.
Is someone else able to re-open it? Or would you prefer it if I were to do raise a new bug?
Thanks,
Steve

Re: [rules-users] Loop Drools on Multi Element
by FrankVhh
Hi,
See forall element in Drools manual:
5.8.3.6.1. Conditional Element forall
It does exactly what you describe. For the record, you may want to insert
all your line items separately to working memory.
Kind regards,
Frank

Session persistence
by Alberto R. Galdo
Hi,
We are using Drools Expert, Fusion, Flow, etc... to build a complex
event processing system and one of our main constraints is to be fault
tolerant. As such, we are using an StatefulKnowledgeSession and our system
involves processes, sets of rules, events, accumulators, ... . What we need
is to be able to reconstruct a KnowledgeSession in a given state and all
our changes in the knowledgesession need to be persisted at the very moment
a change is detected.
The documentation is sparse in this point (
http://docs.jboss.org/drools/release/5.4.0.Beta2/drools-expert-docs/html/...)
and what we've seen so far is that our rules are persisted but no
traces
of facts or events ... This would be unaceptable for our product. We need
to be able to stop our service at any time and restore the knowledge
session at any time as it was at the moment of the previous stop.
We have previous experience with JBPM 3 using a persistent storage to be
fault tolerant and it works like a charm, we can see our processes,
process instances, timers, etc... .
Can we get a *full* KnowledgeSession persistence service for Drools?
Greets,
