Hello
I have built my first few test rules and now I'm working on moving on to
more complex questions. Since I need to monitor data over time I would like
to lern from the example provided here:
http://javabeans.asia/articles/drools_5_case_study_2_complex_event_proces...
Unfortunately I can't get the tutorial to work properly. In eclipse I have
the error marker
----------------------
Description Resource Path Location Type
Error: java.lang.NullPointerException account.drl /SlidingWindowCEP/etc
Unknown Drools Error
----------------------
and upon build and get following error:
----------------------
[81,20]: [ERR 101] Line 81:20 no viable alternative at input '90d' in rule
"NinetyDaysPeriod"
java.lang.IllegalArgumentException: Could not parse knowledge.

at net.javabeansdotasia.casestudy.test.Tester.setUp(Tester.java:54)

at net.javabeansdotasia.casestudy.test.Tester.setUp(Tester.java:56)
at net.javabeansdotasia.casestudy.test.Tester.main(Tester.java:118)
----------------------
Now if I change 90d to 90m the Nullpointer Error goes away but then two new
markers appear at rule "NinetyDaysPeriod" and rule "FiveLastClaims":
----------------------
Description Resource Path Location Type
BuildError: Unable to build expression for 'consequence': [Error: Failed to
compile: 1 compilation error(s):

^
[Line: 1, Column: 0] ' modify($accountInfo) {
setAveOfLastClaims($aveOfLastClaims);
setEligibleForBonusClaims(true);
};
' account.drl /SlidingWindowCEP/etc line 21 Drools Error
----------------------
Description Resource Path Location Type

[Line: 1, Column: 0] ' modify($accountInfo) {
setAveForPeriod($aveForPeriod);
setEligibleForPeriodicBonus(true);
};
' account.drl /SlidingWindowCEP/etc line 65 Drools Error
----------------------
I'm using Drools 5.1 and JDK 1.6 the tutorial is based upon 5.0 and JDK 1.5
could that be the root of my problem? I'm stuck here and still in the
process of learning Java so any hint is appreciated.

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.

rule "my rule"
dialect "mvel"

then
end

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
