[JBoss jBPM] - Problem with a simple process definition using a Timer (JPDL
by Fleury
Hey,
I can not make the process definition below working. The timer seems never to fire. No action is executed. Curiously, a lot of tokens are created in the database...
Could you please test this process definition and report what you observe ? I do not know if the problem comes from my configuration or from jpdl3.2 (this process was working with jpdl 3.1.4).
Thank you very much for your help

The process definition :
<?xml version="1.0" encoding="UTF-8"?>
|
| <process-definition
| xmlns="urn:jbpm.org:jpdl-3.1" name="bistable">
| <start-state name="start">
| <transition name="to_timer" to="Timer"></transition>
| </start-state>
| <state name="Timer" async="true">
| <timer name='startParallelProcesses'
| duedate='1 seconds'
| repeat='30 seconds' transition="to_parallel_processes">
| <action name="action1" class="com.sample.action.MessageActionHandler" async="true">
| <message>Firing timer</message>
| </action>
| </timer>
| <transition name="to_parallel_processes" to="fork1"></transition>
| <event type="node-leave">
| <action name="action1" class="com.sample.action.MessageActionHandler" async="true">
| <message>Leaving timer</message>
| </action>
| </event>
| </state>
| <fork name="fork1" async="true">
| <transition name="to_node1" to="node1"></transition>
| <transition name="to_node2" to="node2"></transition>
| </fork>
| <node name="node1" async="true">
| <event type="node-enter">
| <action name="action1" class="com.sample.action.MessageActionHandler" async="true">
| <message>Entering node1</message>
| </action>
| </event>
| <transition name="to_join1" to="join1"></transition>
| </node>
| <node name="node2" async="true">
| <event type="node-enter">
| <action name="action1" class="com.sample.action.MessageActionHandler" async="true">
| <message>Entering node2</message>
| </action>
| </event>
| <transition name="to_join1" to="join1"></transition>
| </node>
| <join name="join1" async="true">
| <transition name="back_to_timer" to="Timer">
| <action name="action1" class="com.sample.action.MessageActionHandler" async="true">
| <message>Back to timer</message>
| </action>
| </transition>
| </join>
| </process-definition>
The MessageActionHandler class :
| package com.sample.action;
|
| import org.apache.commons.logging.Log;
| import org.apache.commons.logging.LogFactory;
| import org.jbpm.graph.def.ActionHandler;
| import org.jbpm.graph.exe.ExecutionContext;
|
| public class MessageActionHandler implements ActionHandler {
|
| private static final long serialVersionUID = 1L;
|
| String message;
|
| public void execute(ExecutionContext context) throws Exception {
| log.info(message);
| }
|
| private static final Log log = LogFactory.getLog(MessageActionHandler.class);
| }[/img]
