Hello every one:
I am trying to write a little application to familiarize myself with
struts 2. I am trying to design the application using mvc2. the
application is nothing but a small utility for invoices. It store,
retrieves and update invoices. Each invoice belongs to an Account in the
DB. from the examples I have seen so far, the Action class is populated
by values from the jsp page.
So here's my design:
newAccount.jsp
<------> AccountManager.java (ActionSupport)
<----> Account.java
veiwAccount.jsp
Account.java is the class where all the bussiness logic goes.
AccountManager is part of the controller and based on the results it
gets from the Account.java it forwards to the appropriate view. The user
can view an existing account or create one through the jsp pages. Now
because it doesn't make scense to populate the AccountManager with
getters/setters for the same fields in Account, I will pass Account as
an attribute of the request to the view. I mean, if Account.java has
fields , accountID, accountName , ... then I need getters and setters to
access them, but the same getters and setters has to exist in
AccountManager.java so that AccountManager can communicate with the
views. However, I have read some where that because the bussiness logic
may contain other resources ( ie, db connection, ..) we don't pass it
to the view, but we pass a minimal verion of that class as a bean. So, I
'll create another class called ActionBean.java and populate it from
within Account.java .
PLease note that AccountManager can be accessed from many places and
depending on the output it forwards to the correct view.
I need an advice or comments, as I am new to struts 2 and MVC, and I
feel that I am missing something.
Can any one please correct me or give me comments?
