[jboss-user] [JBoss jBPM] - Problem synchronize database with timers

[wanap]

Hello, I've working with timers and I'm very boring of testing things...:(
I'm working with jbpm 3.1.4.

My problem is that I've a simple process with 2 activities:

process-definition
  xmlns="urn:jbpm.org:jpdl-3.1"  name="TaskNode TpoDesarrollo">
  
   
      
   
  
   
   <start-state name="Inicio">
   
      
   </start-state>
   
      
   
		
			
		
    <!--    
         <cancel-timer name='alarma' />
      -->
	
		
   
   <end-state name="Fin">
   
   </end-state>

the First action saves the instance process cause i've read that's necessary to solve some problems with the db and timers.

public class SalvaIDP implements ActionHandler{
	
	private static final long serialVersionUID = 1L;

	@SuppressWarnings("deprecation")
	public void execute(ExecutionContext executionContext) throws Exception {
		System.out.println("EOOOOO-->Ha pasado por el SALVA IDP");
		
		try{
			
			
			ProcessInstance p=executionContext.getProcessInstance();
			JbpmContext.getCurrentJbpmContext().save(p);
			
		}catch(Exception e)
		{e.toString();}

}
}

The second action only makes a System.out.println to makes me secure that it's executed.

public class Traza implements ActionHandler {
	
	private static final long serialVersionUID = 1L;

	@SuppressWarnings("deprecation")
	public void execute(ExecutionContext executionContext) throws Exception {
		
		try{
			System.out.println("EOOOOO-->Ha pasado por el Traza!!!");
			
		}catch(Exception e)
		{e.toString();}
		
		 
		
	}

Here's the error that is displayed on the console...
