Liliana,
I think you got trunk in the middle of a change. Let me explain:
JBoss Rules 3.0 does not support multiple patterns inside "exists".
You can do exists only for a single pattern.
I'm implementing support for that in JBoss Rules 3.1 (trunk), but it
is not complete yet. This
I have modified the rules in this manner:
function boolean test(double n, double m) {
return (n < m);
}
rule "Regola3"
agenda-group"b2";
salience 3;
no-loop true;
when
f2 : ForAllManager( id == "b2") &&
n1 : NumberWrapper(id=="n1") &&
eval(test(n1.getValue()
its possible there is a NPE occurring in one of your consequences:
Exception in thread "main" org.drools.spi.ConsequenceException:
java.lang.NullPointerException at ...
worth while putting some checks in for nulls, see if that is it.

Hi Liliana,
I don't know if it will fix your problem but you don't need the &&'s in
your rules. Rules are "and"ed by default.

n1 : Numb
Hi Liliana,
I don't know if it will fix your problem but you don't need the &&'s in your
rules. Rules are "and"ed by default.
ie.
when
f2 : ForAllManager( id == "b2") &&
n1 : NumberWrapper(id=="n1") &&
eval(n1.getValue() < 100)
should be:
when
f2 : ForAllManager( id == "b2")
n1 : NumberWrapper
Consider the following files :
1)Dynamo_rules_test.java
2)Manager.java
3) ForAllManager.java
4)BooleanWrapper.java
5)StringWrapper.java
6)NumberWrapper.java
-
and consider two simple rules:
rule "Regola 3"
agenda-group "b2";
salience 3;
no-loop

Here it is. Is it any possibilities the exception is caused by drl file? If
any object used in drl file is null, the exception will be thrown at
workingMemory.assertObject() right?
Sorry, a total newbie here.

import com.SystemConfig
import com.Aut
Can you also post the rule(s) you are trying to run?

Hi, I'm currently working on Eclipse3.1+JbossServer+JbossRules. I use
PackageBuilder to
add the source(from Reader), but somehow it throws a NullPointerException at
builder.addPackageFromDrl(source);.
