Taken from the documentation:- 1.6.5.2. Agenda Groups Agenda groups are a way to partition rules (activations, actually) on the agenda. At any one time, only one group has "focus" which means that the activations for rules in that group will only take effect - you can also have rules "auto focus" which means the focus for its agenda group is taken when that rules conditions are true. They are sometimes known as "modules" in CLIPS terminology. Agenda groups are a handy way to create a "flow" between grouped rules. You can switch the group which has focus either from within the rule engine, or from the API. If you rules have a clear need for multiple "phases" or "sequences" of processing, consider using agenda-groups for this purpose. Each time setFocus(...) is called it pushes that Agenda Group onto a stack, when the focus group is empty it is popped off and the next one of the stack evaluates. An Agenda Group can appear in multiple locations on the stack. The default Agenda Group is "MAIN", all rules which do not specify an Agenda Group are placed there, it is also always the first group on the Stack and given focus as default. I would therefore assume that after all activations in the "Check" Agenda Group executed, the MAIN Agenda Group received focus and remaining activations processed. _____ From: rules-users-bounces(a)lists.jboss.org [mailto:rules-users-bounces@lists.jboss.org] On Behalf Of prateek.katiyar(a)wipro.com Sent: 03 October 2007 09:42 To: rules-users(a)lists.jboss.org Subject: [rules-users] Help me Hi I hava a rule file as: <?xml version="1.0" encoding="UTF-8"?> <package name="rules" xmlns="http://drools.org/drools-4.0" xmlns:xs="http://www.w3.org/2001/XMLSchema-instance" xs:schemaLocation="http://drools.org/drools-4.0 drools-4.0.xsd"> <import name="com.wipro.rfq.report.bean.Validator.RFQBean" /> <global identifier="rfq" type="com.wipro.rfq.report.bean.Validator.RFQBean" /> <import name="com.wipro.loan.validation.bean.Final.LoanApplicationBean" /> <global identifier="loanApplication" type="com.wipro.loan.validation.bean.Final.LoanApplicationBean" /> <rule name="Check_NotNullof_rfqId"> <rule-attribute name="agenda-group" value="Check"/> <rule-attribute name="auto-focus" value="true"/> <lhs> <eval>(rfq.getM_rfqId() ==null) || (rfq.getM_rfqId().trim().equals(""))</eval> </lhs> <rhs> System.out.println("The value of m_rfqId is null."); </rhs> </rule> <rule name="Check_NotNullof_partId"> <rule-attribute name="agenda-group" value="Check"/> <rule-attribute name="auto-focus" value="true"/> <lhs> <eval>(rfq.getM_partId() =="null") || (rfq.getM_partId().trim().equals(""))</eval> </lhs> <rhs> System.out.println("The value of m_partId is null."); </rhs> </rule> <rule name="validate_FullName"> <rule-attribute name="agenda-group" value="validate-bean"/> <rule-attribute name="auto-focus" value="true"/> <lhs> <eval>true</eval> </lhs> <rhs> System.out.println("full name is null from xml"); </rhs> </rule> </package> As for the first two rules i declared the agenda group as "Check". Now i want to know that how will i write the code in my java program to activate this agenda group instead of "MAIN". I have already tried with the following option: Agenda agenda=workingMemory.getAgenda(); AgendaGroup Check=agenda.getAgendaGroup("Check"); workingMemory.setFocus(Check); workingMemory.fireAllRules(); But after this when i wrote System.out.println("The focussed agenda group is "+workingMemory.getFocus()); Then the output was The focussed agenda group is AgendaGroup 'MAIN' So now could you please help me.
