Maybe something like:<br><br>rule "Prix premier semestre"<br> when<br> p1 : Produit( eval(dDeb.isBefore(new Date(2010,1,1) ) ) )<br> then<br> p1.setPrix( 10 );<br>
update( p1 );<br>end<br><br>Obviously you'll have to import whatever type of date you're using and change the call to the constructor to match.<br><br>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:<br>
<br>rule "Prix premier semestre"<br>
when<br>
p1 : Produit( dateProperty1 < dateProperty2 )<br>
then<br>
p1.setPrix( 10 );<br>
update( p1 );<br>
end<br>

Dear all,<br><br>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 :<br><br>package com.sample<br> <br>import com.sample.DroolsTest.Produit;<br><br> <br>
rule "Prix premier semestre"<br> when<br> p1 : Produit( dDeb < "01-Jan-2010" )<br> then<br> p1.setPrix( 10 );<br> update( p1 );<br>end<br><br>I get a build error in Eclipse : Unable to create restriction.<br>
<br>This must be an obvious problem but I am struggling for a while now.<br><br>Any help would be appreciated.<br><br>Benoit<br> <br><hr>Commander un cadeau en ligne discrètement? <a href="http://clk.atdmt.com/FRM/go/207186971/direct/01/" target="_blank">Voir la solution offerte par Internet Explorer8</a></div>
