timer repeat count in JBPM4.4

pjazzar Feb 15, 2011 2:28 AM

Hello, I am trying to setup the following scenario:

A task is created and assigned to a person (say person A). the task needs to start sending reminders to person A after 2 days and repeat once a day. However if after X reminders the task is still not completed it needs to escalate.

Any idea how to set this up?

as per the dev guide a timer has two params mainly, DueDate and repeat but no mention of "number of repeats" or something similar.

<timer duedate="20 minutes" repeat="10 seconds" />
      <event-listener class="org.jbpm.examples.timer.repeat.Escalate" />

thanks

Paul.

1. Re: timer repeat count in JBPM4.4

pjazzar Feb 15, 2011 3:40 AM (in response to pjazzar)

Ok so i have been doing some playing around to test different possible setups, here is where i am at now (Still not working):

<?xml version="1.0" encoding="UTF-8"?>

<process name="test" xmlns="http://jbpm.org/4.4/jpdl">

  <on event="start">
    <event-listener class="com.xxx.jbpmEventsActivities.MyEventListener" propagation="enabled">
      <field name="msg"><string value="testing "/></field>
    </event-listener>
  </on>

  <start g="271,50,48,48" name="StartTestProcess">
      <transition name="to task1" to="testTimer" g="-49,-18"/>
   </start>

   <end g="270,458,48,48" name="end1"/>

   <task name="testTimer" g="196,226,202,69">
        <on event="timeout">
          <timer name="reminder" duedate="20 seconds" repeat="10 seconds" />
              <event-listener class="com.xxx.jbpmEventsActivities.TimersNotifications">
                   <field name="msg"><string value="timerEvent "/></field>
            </event-listener>
        </on>

          <transition name="notifyManager" to="state1" g="-53,-18">
              <timer  name="escalate" duedate="1 minute" />
          </transition>
          <transition name="to state2" to="state2" g="13,-15"/>
   </task>

   <state name="notifyManager" g="42,337,158,62">
      <transition name="to end1" to="end1" g="-77,-4"/>
   </state>

   <state name="state2" g="348,333,180,66">
      <transition name="to end1" to="end1" g="15,13"/>
   </state>

</process>

and this is my Event handling class:

package com.xxx.jbpmEventsActivities;

import org.jbpm.api.listener.EventListener;
import org.jbpm.api.listener.EventListenerExecution;


public class TimersNotifications implements EventListener{
    private static final long serialVersionUID = 1L;
    String msg;

        public void notify(EventListenerExecution execution) throws Exception
     {
            String currentActivity = execution.getActivity().getName();
            System.out.println("triggered timer : " + currentActivity + "\n " );

     }
}

The thing is my event listener "on start" is working just fine printing out to the console on entering every state and task. But the timer event is generating an exception "class not found" i have checked the name again and again. i have even replaced com.xxx.jbpmEventsActivities.TimersNotifications with com.xxx.jbpmEventsActivities.MyEventListener and i still got the same exception.

Any clue what's causing this ?

It looks like the JobExecutor thread is not able to resolve the class properly (although a java state outside a timer can do it)... any idea how to configure the jobExecutor so that it can find the classes in my project WAR ?

thanks

Paul.

Hi,

I don't have a direct answer to why the class is not found.
But given that you solve that issue, you might keep track of the number of invocations like this:

public static class PropagationEnabledListener implements EventListener { private static final long serialVersionUID = 1L; public void notify(EventListenerExecution execution) { Integer invocations = (Integer) execution .getVariable("invocations"); if (invocations == null) { execution.setVariable("invocations", 1); } else { execution.setVariable("invocations", invocations + 1); } } }
