Apparently there has been some confusion between the two interfaces called AgendaFilter. But these classes are so simple that you can write your own. import org.drools.runtime.rule.Activation; import org.drools.runtime.rule.AgendaFilter; public class EndAgendaFilter implements AgendaFilter { private final String suffix; private final boolean accept; public EndAgendaFilter(final String suffix) { this( suffix, true ); } public EndAgendaFilter(final String suffix, final boolean accept) { this.suffix = suffix; this.accept = accept; } public boolean accept(final Activation activation) { if ( activation.getRule().getName().endsWith( this.suffix ) ) { return this.accept; } else { return !this.accept; } } } On 19 December 2010 18:47, Benson Fung <benson.redhat(a)gmail.com&gt; wrote:
