if you want to demarcate the transactions even more granular then you have to use async flag for your tasks.
Probably you need a new transaction for every service in the flow and catch all exception.

Abhilash,

Instead of handling the exception, throw it to the function which is calling it. In this way, you get the exception out and you will have its details. I did the same and now I know where exactly the exception has occurred.

I mean if you are using a wrapper in between Activiti and your application, throwing the exception from the wrapper makes more sense. If there is no wrapper, when you get the exception, you can always log it to know where it has occurred.
