Answer Posted / ch.n.v.ganesh
When a user invokes a One Application Server servlet
from a browser, the servlet may invoke one or more
enterprise beans. For example, the servlet may load a
JavaServer Page (JSP) to the user?s browser to request a
user name and password, then pass the user input to a
session bean to validate the input.
Servlet/Jsp EJB
User Interface------> BusinessLogic ---> DataBase
APp Client
After a valid user name and password combination is
accepted, the servlet might instantiate one or more entity
and session beans to run the application?s business logic,
then terminate. The beans themselves might instantiate
other entity or session beans to do further business logic
and data processing.
