Hi,

I wasn't able to reproduce the exact issue (due to some missing classes and not having the same context setup), but here's an example that successfully loads the human task service:

        ClassPathXmlApplicationContext context =
            new ClassPathXmlApplicationContext("spring-conf.xml");

        TaskSessionSpringFactoryImpl springFactory =
            (TaskSessionSpringFactoryImpl) context.getBean("springTaskSessionFactory");       
        springFactory.initialize();

        org.jbpm.task.service.TaskService internalTaskService = 
            (org.jbpm.task.service.TaskService) context.getBean("taskService");
        TaskService taskService = new LocalTaskService(internalTaskService);
        System.out.println("Done setting up " + taskService);

With the following spring configuration file

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns=" http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans"
       xmlns:xsi=" http://www.w3.org/2001/XMLSchema-instance http://www.w3.org/2001/XMLSchema-instance"

    <constructor-arg ref="jbpmTxManager" />
  </bean>

  <bean id="systemEventListener" class="org.drools.SystemEventListenerFactory" factory-method="getSystemEventListener" /> 
  <bean id="taskService" class="org.jbpm.task.service.TaskService" >
    <property name="systemEventListener" ref="systemEventListener" />
  </bean>

  <bean id="springTaskSessionFactory" class="org.jbpm.task.service.persistence.TaskSessionSpringFactoryImpl" depends-on="taskService" >
    <property name="entityManagerFactory" ref="jbpmEMF" />
    <property name="transactionManager" ref="htTxMgr" />
    <property name="useJTA" value="true" />
    <property name="taskService" ref="taskService" />
  </bean> 

</beans>

Hope this helps.
