Получение ошибки при установке drools 6 с помощью spring 4. Метод processData (LicenseCredential) не определен для типа Rule_Renewal_alert_for_60]

Я новичок в Drools. Я настроил новый проект с spring-4.1 и drool-6.1.0.Final. Но когда я пытаюсь запустить проект, я получаю следующие ошибки

Exception in thread "main" org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'autoalert-ksession-stateless': Cannot resolve reference to bean 'autoalert-kbase' while setting bean property 'kBase'; nested exception is org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'autoalert-kbase': Invocation of init method failed; nested exception is java.lang.RuntimeException: Error while creating KieBase[Message [id=1, level=ERROR, path=drools/rules/Rule.drl, line=27, column=0

Вот мои файлы конфигурации spring и drools

слюни-context.xml

<kie:kmodule id="autoalert-module">
    <kie:kbase name="autoalert-kbase" packages="drools.rules">
        <kie:ksession name="autoalert-ksession-stateless" type="stateless"  />
    </kie:kbase>
</kie:kmodule>

<bean id="kiePostProcessor" class="org.kie.spring.KModuleBeanFactoryPostProcessor"/>

applicationContext.xml

<context:annotation-config />

Вот мой файл правил.

    ...
    learnerCsvFileWriter.add(learner);

}

rule "Renewal alert for 60 days"
    when
        licenseCredential : LicenseCredential()
        (
            eval(licenseCredential.getRenewalDeadlineDay() == "0" && licenseCredential.getRenewalDeadlineMonth() == "0") && 
            eval(getCurrentDate().after(getDate(2, licenseCredential.getCourseCompletionDate().getDate(), licenseCredential.getCourseCompletionDate().getMonth()+1))) &&

        )
    then
        System.out.println("Rule For 60 Days Called");      
        processData(licenseCredential);

Вот мой основной файл

public static void main(String[] args){ 

    final ApplicationContext context = new ClassPathXmlApplicationContext("classpath:spring/applicationContext.xml");

    LicenseCredentialDAO dao = (LicenseCredentialDAOImpl)context.getBean("licenseCredentialDAO");
    List<LicenseCredential> objectList = dao.select();

    BusinessRuleProcessor ruleProcessor = (BusinessRuleProcessor)context.getBean("businessRuleProcessor");
    ruleProcessor.configureAndApplyRulesOnObject(objectList);

    CsvFileWriter learnerCsvFileWriter = context.getBean("csvFileWriter", CsvFileWriter.class);
    learnerCsvFileWriter.writeCsvFile("abc.csv");

}

Вот мой класс BusinessRuleProcessor

public class BusinessRuleProcessor {
    private StatelessKieSession statelessKieSession;
    private CsvFileWriter csvFileWriter;

    // getters and setters

    public void configureAndApplyRulesOnObject(List<LicenseCredential> objectList){

        statelessKieSession.setGlobal("learnerCsvFileWriter", csvFileWriter);
        statelessKieSession.execute(objectList);

    }
}

Почему я получаю сообщение об ошибке

function processDataprocessData (line:27): learnerCsvFileWriter cannot be resolved

Rule Compilation error The import defaultpkg.ProcessData cannot be resolved

The method processData(LicenseCredential) is undefined for the type Rule_Renewal_alert_for_60_days2039807096]

Пожалуйста помоги.

Спасибо
