getCommandService() is a method to connect with the EJB, it's based on the EJB provided with jBPM but statefull.
I also looked at the logs and no exception pop's up.
Isn't a execution of NewProcessInstanceCommand enough to start a instance and get that on the corresponding tasklist? Does it need something more?
I've seen some other examples that have a lot more code than the NewProcessInstanceCommand implementation.
I'm really on a dead end here, help?
