I think that you already know the answer of the question. You post another question about the human tasks APIs. using the TaskClient / TaskService (now in 5.2) you can get the information of the pending tasks for your users. If you add the jbpm-human-task dependency to your web application you will be able to get the information about the pending task and render it inside a web application, no matter the framework that you are using.
Thanks for the replies, Mauricio
I ll see how I can make it possible, and will post my work here.
That will be great.. you already have all the pieces to make it work
