[jboss-user] [JBoss jBPM] - jBPM timer and scheduler

I'm posting here because I can't find lot's of information about how to set up timers in jBPM.

I've added a timer to my task :

			<timer name="waitForApproval"
  | 				duedate="1 minute"
  | 				transition="validee" >
  | 				<script>
  | 					System.out.println("Le valideur est trop lent : valid????e !!!");
  | 				</script>
  | 			</timer> 

It seems timers need what you call a scheduler service. After some researches, I find out that I must add this to my web.xml :

  | 	<servlet>
  | 		<servlet-name>JbpmThreadsServlet</servlet-name>
  | 		<servlet-class>org.jbpm.web.JbpmThreadsServlet</servlet-class>
  | 		<load-on-startup>1</load-on-startup>
  | 	</servlet>
  | 	<servlet-mapping>
  | 		<servlet-name>JbpmThreadsServlet</servlet-name>
  | 		<url-pattern>/threads</url-pattern>
  | 	</servlet-mapping>

I did that, but I find an exception :
java.lang.ClassNotFoundException: org.jbpm.web.JbpmThreadsServlet

And surprise! There is no such class in my jbpm jar file. I took the last one from jbpm-installer-3.2.6.SP1.jar : jbpm-jpdl.jar

On JarSearch, I found that the class is present only in version jbpm-3.1.4.jar and before.

So what am I doing wrong, or what did I miss?
