[jbpm-users] Email Service Task. JBPM 5.1

Hello, I am reading about Service Tasks. This a good video explaining how we can create Service Tasks: http://vimeo.com/29457538. Ok my point is when you open the eclipse BMPN editor there are two Service Tasks Log and Email. But i don't find this configuration files to both Service Tasks. So how were they added? One last thing, by default the eclipse create a Hello Process. I tried to modify this process adding the Email Service Task, but when i tried to run the application I got an exception: Could not find work item handler for Email at org.drools.process.instance.impl.DefaultWorkItemManager.internalExecuteWorkItem(DefaultWorkItemManager.java:71) at org.jbpm.workflow.instance.node.WorkItemNodeInstance.internalTrigger(WorkItemNodeInstance.java:105) It's complaining about the work item handler, but where they were supposed to be?
