Hi all,
Can u pls tell me the answers to the following questions:
1. If 1000 users are accessing StateLess Session Bean, how many instances
of it are created on the server (say Weblogic v6.1) ?
2. When should we use Entity Beans ? If I have to update only 1 field of 1
table, should I use Entity Beans or not ????? Also, if there are 2/3
tables
to be inserted or updated, should I go for 2/3 Entity Beans or should I
go for only StateLess Session Bean without using Entity Beans ?????
3. If there r multiple screens, say registration process involving 5 to 6
screens, what should we use?
a. Stateful Session Bean or
b. Simple HttpSession Object keeping the data in the session till 6th
screen
& then in the last screen, insert it into the database. or
c. Simple HttpSession Object keeping the data in the session & inserting
it
in the subsequent screens into the database.
d. Using a Stateless Session Bean
4. Finally, if I can do all the programming using JSP, Servlets & simple
beans, then why should I go for EJBs ?
I've seen plenty of sites of EJBs but still couldn't get the proper
answers to the above questions. Hoping to get it from u guys.
Thanks & Regards,
Prashant
