Good Morning!
I'm an italian student, Domenico.
I will be very grateful if you could answer me about Some EJB question:
1. a bean instance (session and entity) has a own remote class?
2. all instances of a bean share the same instance of home class or an instance has a
own home class?
3. What are the advantages in keeping session with session bean and EJB
instead of Session Tracking and Servlet?
4. What are the advantages in using bean-managed transaction instead of
container-managed ones?
5. Does J2ee function as Web server or is it necessary to install Java
Web Server or Apache?
6. About transction isolation levels:
is it true that if I use stored procedures the isolation is a matter
of DBMS, while if I use SQL statement the isolation is a matter of programmer
(I mean if I use stored proc, must I declare transaction isolation level?) ??
7. Is it true that an entity bean is compelled to use container-managed
transaction? Why?
8. May I defini a session bean that has an entity bean as its own field?
I hope you will answer me asap, because it's very important for my thesis.
Thanks in advance for the patience!
