[rules-users] Drools-Spring Config for Knowledge Agent

[KiranP]

Hello Everybody,

I've used Drools5.1.0 and I have following Config In Spring : 


        <drools:resource id="profileChangeProcess" type="DRF"
source="classpath:/process/profilechangeprocess.rf"></drools:resource>
        <drools:resource id="documentsRule" type="DRL"
source="classpath:/rules/documentsrule.drl" />
        <drools:resource id="ChangeSet" type="CHANGE_SET"
source="classpath:/ChangeSet.xml"></drools:resource>

        <drools:resource-change-scanner id="scanner" interval="10" /> 
          
        <drools:kagent id="agent" kbase="knowledgeBase" new-instance="true"> 
                <drools:resources> 
                        <drools:resource 
ref="profileChangeProcess"></drools:resource>
                        <drools:resource ref="documentsRule"></drools:resource>
                        <drools:resource ref="ChangeSet"></drools:resource>
                </drools:resources> 
        </drools:kagent> 

        <drools:kbase id="knowledgeBase"></drools:kbase>

now when i run the code i get following exception : 

 org.springframework.beans.factory.BeanCreationException: Error creating
bean with name 'kSession': Error setting property values; nested exception
is org.springframework.beans.NotWritablePropertyException: Invalid property
'knowledgeAgent' of bean class
[org.drools.container.spring.beans.StatefulKnowledgeSessionBeanFactory]:
Bean property 'knowledgeAgent' is not writable or has an invalid setter
method. Does the parameter type of the setter match the return type of the
getter?
