This is the way to implement an AgendaFilter so that you can use it with ksession.fireAllRules

import org.drools.runtime.rule.Activation;
import org.drools.runtime.rule.AgendaFilter;

public class MySimpleFilter implements AgendaFilter {
   // ... constructor etc.

   public boolean accept(Activation item) {
         return true; // change this, using constructor arguments ...
    }
 }
 
AgendaFilter  mySimplefilter = new MySimpleFilter(...);
session.fireAllRules( mySimplefilter );

Through Activation you get at the rule and the rule name, and your accept method can be more sophisticated.

Re: [rules-users] Please help me to fix the AgendaFilter related        issue





The error message says StatefulRuleSession, but I'd say you have a StatefulKnowledgeSession ksession.

Do a cast:
   org.drools.runtime.rule.StatefulRuleSession sfrs = (org.drools.runtime.rule.StatefulRuleSession)ksession;
and use this one for firing all rules with an agenda filter.

Eclipse is showing that there is a method fireAllRules() which takes
AgendaFilter as a parameter
but I am getting error "The method fireAllRules(int) in the type
StatefulRuleSession is not applicable for the arguments (AgendaFilter)" at
'ksession.fireAllRules(agendafilter);'

I am trying to execute specific rules out of set of rules. Please help me to
fix this issue.
