Re: [rules-users] Getting a Drools Fusion - CEP Example to work
Thank you for your reply.
Yes sure I have that. I took the rules directly from
http://javabeans.asia/articles/drools_5_case_study_2_complex_event_proces...
and they include this setting.
As posted in my fist mail I needed to change 90d in following code to
90m to get the tutorial to work.
from accumulate(
ClaimApprovedEvent(
accountNumber == $account.number,
$amount : amount
)
over window:time( 90d ) from
entry-point ClaimStream,
average($amount)
)
I can use 's', 'm' or 'h' only with 'd' I get an error
marker in eclipse:
Description Resource Path Location Type
Error: java.lang.NullPointerException account.drl
/SlidingWindowCEP/etc Unknown Drools Error
btw.: The tutorial seems to use some discouraged Classes so I have quite
a few warnings
about PackageBuilderConfiguration, MVELDialectConfiguration and
SessionPseudoClock
however I have the same issues with this as written here:
http://drools.46999.n3.nabble.com/Fixing-the-quot-Discouraged-access-quot...
("Accessible" setting in eclipse makes all org.drools imports unresolved)
References for ppl interested in the discouraged warning:
http://drools.46999.n3.nabble.com/quot-Discouraged-access-quot-warnings-w...
http://drools.46999.n3.nabble.com/Problem-with-CommandFactory-newStartPro...
It seems to me I must have some basic setting wrong but I have yet to
figure out what it is,
so hints are still very much appreciated.
Best regards,
Sebastian

did you try setting the mvel dialect inside the rules?
rule "my rule"
dialect "mvel"
when
then
end
??

Now I realy feel a bit silly. I banged my head on this for hours
and then
just after I write you I get a step further. I changed mvl mode
and replaced
line 78 in Tester.java with:
PackageBuilderConfiguration conf = new PackageBuilderConfiguration();
((MVELDialectConfiguration)
conf.getDialectConfiguration("mvel")).setStrict(false);
((MVELDialectConfiguration)
conf.getDialectConfiguration("mvel")).setLangLevel(5);
KnowledgeBuilder builder =
KnowledgeBuilderFactory
.newKnowledgeBuilder(conf);
Now the markers are still being displayed but the code compiles
and runs. If
someone would take the time to explain this to me I'd be very
thankful.
