Re: Problem of multiple clients request concurrently 1 session stateful bean

Certainly, if your intent is to allow multiple clients to access shared
data, EJB might not be a way to go.  You may want to model your objects
as Entity Beans, however, this will incur certain performance
penalties.  If you were to layout your problem  with some real
constraints, a real solution might be possible.  Certain tasks are just
not well suited for some technologies.  What solution would you give me
if I wanted to write HTTP server using Oracle PL/SQL stored procedures?
