Getting WorkflowInstance of a given DelegateTask in Java

Hi Forum, I have an Activiti task that invokes a custom Java. In the custom Java I need to send an email to the workflow initiator with an update. I'm a little stuck on how to get the WorkflowInstance given the current task so I could get the initiator. My code snippet is below.public class Mail

ScriptTaskListener implements TaskListener
–>public void notify(DelegateTask delegateTask)
—->DelegateTask extends VariableScope
public interface VariableScope –> Object getVariable(String variableName)
Therefore, delegateTask.getVariable("initiator") will return the Task Initiator.
I expect it is an ActivitiScriptNode, so you may have to do a getNodeRef call on the returned object.
HTH, let me know if I am being a little too terse ;-).

Thanks so much mstang. That was plenty of information to get started in the right direction. This is the code snippet for anyone else.

ActivitiScriptNode actScriptNode = (ActivitiScriptNode) task
      .getVariable("initiator");

   NodeRef nodeRef = actScriptNode.getNodeRef();
   Map<QName, Serializable> props = getServiceRegistry()
         .getNodeService().getProperties(nodeRef);
   Set<QName> keys = props.keySet();
   for (QName qname : keys) {
      if (qname.getLocalName().equalsIgnoreCase("email")) {
         String email = (String) props.get(qname);
      }
   }
