Which version are you using?
The RuleAgent is not part of the public API and has not been developed for
some time..
could you please use the KnowledgeAgent instead (see section 3.2.6 in the
manual),
and let us know if you still have problems?
Thanks

Hi,
I have been trying to write the following code to automatically deploy any
changes made to the rules. However i am getting nullpointerexception errors.
I see many posts regarding this topic and have tried different options but
the error won;t go away.
public static void main(String[] args) {
FWIW, the corrected rule works, irrespective of the position of the "exists" CE.
rule killphone
when
exists Customer()
$unused: Phone( $value: value )
not Customer( phone == $value )
then
retract( $unused );
end

I can't say much about drools server. I went for a Spring web app wrapping a

We are refactoring internal api's, JSR94 will need to move public apis. So we
have to decide if it's worth spending the week refactoring it, or whether we
just remove it. Our resources are finite, so it's always good to review what is
really necessary.
It's about the same amount of time to add

If you consider Drools Expert (the core engine) as a component, then
certainly, yes, it can be integrated into a system that both utilizes
persistence and communicates via web services in various ways respectively.
As for working examples, I'm of the opinion that would be stretching the

Yeah, you are right, i was talking about fact events.

You could try using a combination of BRL Fragments and DSL.
Define your DSL as the expression: [when]My calendar is between {p1} and
{p2)=eval( myCal.isInInterval("{p1}", {p2}") and use the DSL in a BRL
Fragment.
With kind regards,

Drools "rule engine" otherwise known as Drools Expert does not use JCR by
