Problem with date
by Bertrand Grottier
Dear all,
I am a newbie with Drools (Drools 5). I just want to make a date comparison but failed until now. Here is my drl file :
package com.sample
import com.sample.DroolsTest.Produit;
rule "Prix premier semestre"
when
p1 : Produit( dDeb < "01-Jan-2010" )
then
p1.setPrix( 10 );
update( p1 );
end
I get a build error in Eclipse : Unable to create restriction.
This must be an obvious problem but I am struggling for a while now.
Any help would be appreciated.
Benoit

SAP JCO (Drools)
by Young Matthew (4004)
Searched the mail archives....
About using Drools with SAP via JCO (similar to how SAP connects to
RuleBurst) without finding any information. Just wants to pool the
mailing list again to see if there are any active Drools/SAP users and
their experience writing a JCO package for DRools.

How to traverse the Collection by index
by dhari
Hi all,
I want to compare all elements in the collection with other element of the
same collection. In my case I have collection of Segment, a Segment contains
startDate and endDate. The whole collection of Segment should consists on
complete calendar year and every segment in the list must start 1+ from the
endDate of last element. Valid fact should be:
MemberShip
Segment 1: StartDate: 01-01-2010 EndDate: 30-05-2010
Segment 2: StartDate: 31-05-2010 EndDate: 08-08-2010
Segment 3: StartDate 09-08-2010 EndDate: 31-12-2010
Data structure
class Segment{
java.util.Date startDate;
java.util.Date endDate;
}
class Membership{
java.util.ArrayList<Segment> segments;
}
I know the date functions. I just want to know how can I traverse the List
from get element on Index and Index+1?
