I'm reading "Programming Jakarta Struts" and am in need of a little
clarification. 

According to the book, a "service" creates business objects. 

The action class gets business objects from the service

Business objects perform their own business rules validation.



What if the validation of a business rule requires a number of different
business objects together in the same place at the same time? Can one have a
"BOContext" object that would combine different business objects just for the
validation of a particular rule? And if so, who would invoke a BOContext, the
action or the service?

Thanks,

Heather
