Thanks Maciej,
However I´m reading two options that could work for me and maybe you could provide some information:
1.- Create a new Work Item Definition in Guvnor with the Designer and create a Work Item Handler on my WebApp. And when I start my application link my handler with the item definition. I don´t know if I understand all the implementation details.
2.- To use the project: jBPM5-Executor-Service but I don´t know if it wich solution provides me a clean solution.
Thanks!
