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.
