Hi, What is the type of the dDeb field? It looks like you're trying to check if a date is less than a string. Enda 2010/3/3 Bertrand Grottier <b_grottier(a)hotmail.com&gt; -- Enda J Diggins

How was suggested before (in other thread) you can: 1) use getTime() method of Date class which return "long" and compare 2) use some good library for example Joda time with eval() Pavel 2010/3/8 Bertrand Grottier <b_grottier(a)hotmail.com&gt;:

Thank you for your help. I tried the solution you proposed but encountered the following error message: [10,27]: [ERR 101] Line 10:27 no viable alternative at input 'new' in rule "Prix premier semestre" in pattern Produit [10,36]: [ERR 102] Line 10:36 mismatched input '2010' expecting ')' in rule "Prix premier semestre" in pattern Date Eventually, I had to adapt the rule in the following way: rule "Prix premier semestre" when $p1 : Produit(id == 1) eval ($p1.dDeb.before(new Date(2010,3,1) ) ) then $p1.setId(2) ; $p1.setPrix(10) ; update( $p1 ); end The test on the id shouldn't be necessary but I can't make it work without. So, the current version is not very clean. Have you got an idea ?

I may be wrong but I think you need to use eval here because you want to create the comparison date within the rule. If you had already created the date using "<" would be fine: rule "Prix premier semestre" when p1 : Produit( dateProperty1 < dateProperty2 ) then p1.setPrix( 10 ); update( p1 ); end 2010/3/8 Bertrand Grottier <b_grottier(a)hotmail.com&gt; Hello, Ok, I understand the problem. dDeb is indeed a Date type. What is the proper/simplest way to achieve such a comparison ? Thank you in advance for your help.

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 Commander un cadeau en ligne discrètement?
