Re: Activity scope variables

Hi Monique,
thanks for your reply.

You gave me an alternative way if I use a JavaToolAgent, but there is an 
alternative if I dont use any agent ?
Suppose for example that I ask to shark (with Java code) for the 
activities that my user have to complete, and analizing some parameter 
of the activity I execute different tasks to complete the activity. All 
this through the Shark API, called by my code.

What do you suggest in this case ?

Gianfranco
