<div dir="ltr">Hallo Edson,<br><br>thanks for the quick answer. Where can I find the configuration file where I have to define the ne accumulate function:<br><pre class="programlisting">drools.accumulate.function.calculateCertainty = org.drools.base.accumulators.NewAccumulateFunction<br>
</pre><br>regards<br>Thomas<br><br><br> Or an accumulate function (as long as all you objects implement a commong<br>interface):<br><br>rule "overall certainty"<br>when<br> $cert : Number() from accumulate(<br>
$f : CertaintyFacts( ),<br> overallCertainty( $f ) )<br>then<br> // do something with $cert<br>end<br><br> Implement your own formula inside overallCertainty function .<br><br> []s<br> Edson<br>
