Show UI messages on BPT Activity updates in Reactive Web application

In Reactive Web application how can I update the UI elements on Process or Activity completion?

So if I have 3 Automatic Activities in a Process how can show message on UI on each Activity completion & then on Process completion?

Hi Hemant,

I'm not very sure whether its possible for the BPT engine to call back to the web page. 

Would it be possible to implement a simple javascript timeout that calls a client action at intervals to poll the activity/process tables to get the values?
