[jboss-user] [JBoss jBPM] - Check if a process definition is deployed

[rodosa]

Hello!!

   I'm trying to check if an process definition is deployed. I use this code to check it:


  | Definition definition = null;
  | 	
  | ExecutionService executionService =jbpmServiceFactory.openExecutionService("admin");
  | definition = executionService.getLatestDefinition( "altaProyecto" );
  | executionService.close();
  | 
  | 

My process definition is very simple. It hasn't anything special. Only 3 tasks that don't do any.


  | <?xml version="1.0" encoding="UTF-8"?>
  | 
  | <process-definition  xmlns=""  name="altaProyecto">
  |  
  |  	<swimlane name="boss">
  |     <delegation class="org.jbpm.delegation.assignment.ActorAssignmentHandler">admin</delegation>
  |   </swimlane>
  | 
  | 
  | 	<start-state name="Introducir datos del proyecto">
  | 		<transition to="task-node1" name="to task-node1"></transition>
  | 	</start-state>
  | 
  | 
  | 	<task-node name="task-node1">
  | 		<transition to="Fin"></transition>
  | 	</task-node>
  | 
  | 
  | 	<end-state name="Fin"></end-state>
  | 
  | 
  | </process-definition>
  | 

but it is thrown the following exception:


  | 12:45:52,811 ERROR [LogInterceptor] RuntimeException in method: public abstract
