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"

       xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

Hope this helps.
