Here's a chunk of code from the execute() method of the com.someco.bpm.ExternalReviewNotification class included with the Alfresco Developer Guide book. It is grabbing the node name here with getName() but there is a getId() method as well.


    String recipient = (String) executionContext.getVariable(ExternalReviewNotification.RECIP_PROCESS_VARIABLE);
    StringBuffer sb = new StringBuffer();
    sb.append("You have been assigned to a task named ");
    sb.append(executionContext.getToken().getNode().getName());
    sb.append(". Take the appropriate action by clicking one of the links below:\r\n\r\n");
    List transitionList = executionContext.getNode().getLeavingTransitions();
    for (Iterator it = transitionList.iterator(); it.hasNext(); ) {
        Transition transition = (Transition)it.next();
        sb.append(transition.getName());
        sb.append("\r\n");
        sb.append("http://localhost:8080/alfresco/service/someco/bpm/review?id=jbpm$");
        sb.append(executionContext.getProcessInstance().getId());
        sb.append("-@");
        sb.append("&action=");
        sb.append(transition.getName());
        sb.append("&guest=true");
        sb.append("\r\n\r\n");
    }‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍

Hope that is what you were looking for.

if you are using Eclipse with autom-completion, have a look at executionContext.getInstance() or executionContext.getTask().

There should be some
executionContext.getTask().getId();

or
executionContext.getTaskInstance().getId();

I'm trying jpotts example, I changed:

executionContext.getProcessInstance().getId()
to
executionContext.getTaskInstance().getId()

but executionContext.getTaskInstance() is null, how come? executionContext.getTask() is also null.

I found my mistake, in my jPDL file I was calling my code in the event "node-enter", I changed that to the event "task-create" and getTaskInstance() isn't null anymore.

I am also having the similar requirement. Can you please post your complete processdefinition.xml for customized jbpm.

Thanks in Advance.
