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:
