for example, in group A, there's EJB_1 and in group B, EJB_2. If the EJB_2 use some data created by the EJB_1, how to implement it? In our practice, when "RUN" the above method, there is no error but we couldn't get the returned data from EJB_1.
BTW, this's the first time for me to realize that my specialized English in CS is very poor. I feel difficult to explain a little bit complex problem. So sorry for my ambiguity.
