[rules-users] Problem with date

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.
