[jboss-user] [JBoss jBPM] - Error on deploying business process

[t.schenk]

Hello all together,

i changed the sample process from the starter kit in that way, that i added an node with an actionhandler and removed the task-node. My process is described as the above xml-statement:

<?xml version="1.0" encoding="UTF-8"?>
  | 
  | <process-definition 
  |   xmlns="urn:jbpm.org:jpdl-3.1"
  |   name="simple">
  |    <start-state name="start">
  |       <transition name="Step1" to="node1">
  |       </transition>
  |    </start-state>
  |    <end-state name="end"></end-state>
  |    <node name="node1">
  |       <transition name="Step2" to="end"></transition>
  |    
  |       <action class="com.sample.action.MessageActionHandler">
  |          <message>Test</message>
  |       </action>
  |    </node>
  | </process-definition>

The deployment of the above process ends with the following error:

When i changed the process in a way, that the transition performs my action and not the node i can deploy the process without any problem. The process that can be deployed is the following:

<?xml version="1.0" encoding="UTF-8"?>
  | 
  | <process-definition 
  |   xmlns="urn:jbpm.org:jpdl-3.1"
  |   name="simple">
  |    <start-state name="start">
  |       <transition name="Step1" to="node1">
  |          <action name="action1" class="com.sample.action.MessageActionHandler">
  |             <message>Test</message>
  |          </action>
  |       </transition>
  |    </start-state>
  |    <end-state name="end"></end-state>
  |    <node name="node1">
  |       <transition name="Step2" to="end"></transition>
  |    
  |    </node>
  | </process-definition>

Can someone find out why i cann't deploy the process with the node actionhandler ???
