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...
13:29:20,446 INFO [STDOUT] EOOOOO-->Ha pasado por el SALVA IDP
