[rules-users] execute specific rule using agenda

Hi, I would like to execute specific rules from the rule file(.xml). Find the rule file content below. There are three rules are available in the xml file(Rule names: 1.Check_NotNullof_rfqId , 2.Check_NotNullof_partId and 3.validateFullName) First time we are trying to execute 1.Check_NotNullof_rfqId and 2.Check_NotNullof_partId rules. next time we are trying to execute 3.validateFullName rule We have tried the following option The rule name start with "Check" require to set only "rfq" global identifier. So when we execute first two rules we followed following approach workingMemory.setGlobal("rfq",rfqbean); workingMemory.fireAllRules(new RuleNameStartsWithAgendaFilter( "Check" )); but it gives following NullPointerException. It is trying to execute validatefullname rule also. Caused by: java.lang.NullPointerException at rules.Rule_Check_NotNullof_rfqId_0.eval0(Rule_Check_NotNullof_rfqId_0.ja va:9) at rules.Rule_Check_NotNullof_rfqId_0Eval0Invoker.evaluate(Rule_Check_NotNu llof_rfqId_0Eval0Invoker.java:16) at org.drools.rule.EvalCondition.isAllowed(EvalCondition.java:71) ... 12 more When we execute third rule alone. we followed following approach workingMemory.setGlobal("loanApplication",loanApplicationbean); workingMemory.fireAllRules(new RuleNameStartsWithAgendaFilter( "validate" )); Please help us to resolve this issue XML rule File <?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" /> <rule name="Check_NotNullof_rfqId"> <!--start of rule 1--> <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"> <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> <import name="com.wipro.loan.validation.bean.LoanApplicationBean" /> <global identifier="loanApplication" type="com.wipro.loan.validation.bean.LoanApplicationBean" /> <rule name="validateFullName"> <lhs> <eval>loanApplication.getFullName() == null || loanApplication.getFullName().trim().equals("")</eval> </lhs> <rhs> System.out.println("full name is null from xml"); </rhs> </rule> </package> The information contained in this electronic message and any attachments to this message are intended for the exclusive use of the addressee(s) and may contain proprietary, confidential or privileged information.
