Hello Mauricio,
Thank you very much for this information.
I take a look to your link, download the zip of the master branch and build the jbpm-human-task-service, so I obtain jars. I import them to my project but I am not sure about how to use it, because for what I see a lot of functions are not yet implemented. Is it really usable from now?
But it will be very usefull, espacially the adminTaskService.
You make a very good job with jbpm.
Regards
