Hi all,
I know the question is very silly, but I am sorry I
could not avoid asking your help.
I follow the MVC design methodology in my web
framework which has got servlets, jsp and beans.
JSP page forwards the request to the controller
servlet requesting for a certain action.
The servlet controller after receiving the request
object,instantiates the appropriate
business bean, which will use connection pool manager
and data access beans for manipulating
the data. After completing the data handling
operations, the servlet
controller returns the manipulated data back to a new
JSP page.
Now my question :
How is the conversion/ translation of the action (say
for example updation, insertion or deletion) which is
coming from the client JSP page done by the controller
servlet taken to the
right instance of business bean ? A single page may
have more than one action. Now, how do the controller
servlet calls the UpdateBusinessBean for update action
and InsertBusinessBean for insert action ? The method
that will be used by the client to invoke the servlet
is "POST". Can I ask you, what are the possible ways
of doing this, (Already I have adopted one method in
my last assignment, but I am not too happy about it,
as it did not consider scalabilty issues and also it
was tightly coupled.)
Manisha
