  | <process-definition 
  |   xmlns="urn:jbpm.org:jpdl-3.2"
  |   name="simple">

  |          <action name="action" class="com.sample.action.MessageActionHandler">
  |             <message>Going to the first state!</message>
  |          </action>
  | 
  |

Instanciation code:


  | 
  | JbpmConfiguration jbpmConfiguration = JbpmConfiguration.getInstance();
  |         JbpmContext jbpmContext = jbpmConfiguration.createJbpmContext();
  |         try {
  |             
  |             ProcessInstance processInstance = null;
  |            ProcessDefinition processDefinition = jbpmContext.getGraphSession().getProcessDefinition(15);
  | 
  |            processInstance = (ProcessInstance)processDefinition.createInstance();
  |            processInstance.signal();
  | 
  |             jbpmContext.save(processInstance);
  |            
  |         }
  |         catch (Exception e) {
  |             e.printStackTrace();
  |         }
  |         finally {
  |                 jbpmContext.close();
  |         }
  |
