org.eclipse.jdt.internal.compiler.CompilationResult.getProblems()[
by bhavindalal
Hello,
I am new to Drools. On starting to execute a simple program, eclipse gives
the following stacktrace as error. I even included the org.eclipse.jdt that
comes with eclipse, but it is still giving me error. Anybody please suggest
the problem. I am using Drools 5.0 and its dependencies and Eclipse Helios
java.lang.NoSuchMethodError:

a newbi question
by wutongjoe
hello all,
I am a newbi on Drools and started my test work with a modified exapmle
included in drools v4.0.7.The compiled drl from a very simple modified xls
file is like the follwing :
----------------------code-----------------------
package org.drools.examples.decisiontable;
#generated from Decision Table
import org.apache.commons.lang.time.DateUtils;
import java.util.Date;
#From row number: 11
rule "Pricing bracket_11"
when
DateUtils.SEMI_MONTH==1001
then
policy.setBasePrice(9999999);
end
-------------------------code---------------------
but I got an exception stack when trying to addPackage after compile :
--------------stack----------------
Exception in thread "Main Thread" org.drools.rule.InvalidRulePackage:

inside a xls file,but it seemed something went wrong.Can someone tell me
what caused the exception? thanks a lot

Based on the stack trace I would guess that the file Sample.pkg contains a
serialized KnowledgeBase and not a serialized KnowledgePackage. Maybe you
could try to do your export like this:
KnowledgeBase kbase = ...;
KnowledgePackage kpackage = kbase.getKnowledgePackages().iterator().next();
FileOutputStream fos = new FileOutputStream(new File("c:/Sample.pkg"));
DroolsStreamUtils.streamOut(fos, kpackage);

when should we the not operator.
by arun1979
Below is the code
declare EventX
@role( event )
@timestamp( eventDate )
@expires( 2m )
end
rule "test rule"
no-loop
when
event : EventX(eventType == 'XYZ', $oId :Id)
not ( EventY(eventType == 'ABC', Id == $oId, this after[0s,8s] event))
then
//fire the rule. code never reaches here if EventY does not occur at all
end
Can someone help me in understanding what i am doing wrong. I tried removing
the not and inserting EventY and it works fine. The eventDate is also
populated for both events.
Thanks
Arun
