Where is jbpm-5.3.0.Final-src.zip?

[devilkazuya99]

I'm looking for the source code files.

Because when I run

          private org.jbpm.task.TaskService localTaskService;

          private org.jbpm.task.service.TaskService taskService;

  ...

  ... 

  localTaskService = new org.jbpm.task.service.local.LocalTaskService(taskService);

I get

Caused by: java.lang.NullPointerException

Got the source from GitHub.

https://github.com/droolsjbpm/jbpm/zipball/master

Also notice something. My NullPointerException was caused by

  <bean id="taskService" class="org.jbpm.task.service.TaskService">
             <property name="systemEventListener" ref="systemEventListener" />
  </bean>

from drools-spring integration documentation. After looking at the souce code of

org.jbpm.task.serviceTaskService, the constructors are like:

TaskService(EntityManagerFactory emf, SystemEventListener systemEventListener)

and

TaskService(EntityManagerFactory emf, SystemEventListener systemEventListener, EscalatedDeadlineHandler escalationHandler)

So I change my spring setting to:

    <bean id="taskService" class="org.jbpm.task.service.TaskService">
        <constructor-arg name="emf" ref="htEmf" />
        <constructor-arg name="systemEventListener" ref="systemEventListener" />
    </bean>

and it works (for now).
