                 URL: https://issues.jboss.org/browse/JBRULES-2868
             Project: Drools
          Issue Type: Bug
      Security Level: Public (Everyone can see)
          Components: drools-spring
    Affects Versions: 5.2.0.M1
            Reporter: bodi bajk
            Assignee: Mark Proctor
             Fix For: FUTURE


Stack trace:
Caused by: java.lang.NullPointerException
	at org.drools.container.spring.namespace.KnowledgeSessionDefinitionParser.parseInternal(KnowledgeSessionDefinitionParser.java:321)
	at org.springframework.beans.factory.xml.AbstractBeanDefinitionParser.parse(AbstractBeanDefinitionParser.java:59)

For example, my applicationContext.xml:

.....
  <bean id="config" factory-method="getConfiguration" factory-bean="configFactory" />
.....


solution:


class: org.drools.container.spring.namespace.KnowledgeSessionDefinitionParser
method: parseInternal

line : 
  if ( def.getBeanClassName().equals( KnowledgeAgentBeanFactory.class.getName() ) ) {
             
should be replaced with somethig like this:
 if ( KnowledgeAgentBeanFactory.class.getName().equals( def.getBeanClassName() ) ) {
