Thanx Ronald for the reply.
One solution which I have thought of is
I have a data object let's say called UserData which has all the
instance variables and getter/setter methods.
Now both User Form and User Business object have a instance variable of
this UserData object which they use.
This way if my data is changing I just have to change it at one place
i.e. my UserData class.
Are we both essentially talking the same thing ??
Thanx
Rajesh

I'm not using Struts for a very long time now, but I think this is NOT
the way to do this.
In your ActionForm bean called User I would put the getter/setter
methods. In your UserBO (User Business Object) I would put the methods
that make use of the UserDAO (User Data Access Object). The UserBO is
only for handling the business logic in your form/application. The
UserDAO actually executes the real SQL queries or XML update functions.
So, User extends ActionForm and is really a simple mapping of your form
in your application.
In your Action class (belonging to this User form) you map the User bean
and give it as an argument with any function of your UserBO object which
will execute the desired action (update/create/delete etc.).
Hope I helped you a bit. Maybe other people have better solutions, but
this is the way I handle actions...
Good luck
Regards,
Ronald

Subject: Duplication of code in Business objects and Action forms
Hi All
I am new to Struts so please bear with me.
We have started implementing a new product using struts.
Now I do see that I need to have getter /setter methods declared on
both
my
business objects as well as Action form.
So for e.g if I had a User business object which encapsulates the
entire business login for my system user. Now I will have UserForm
class also which will have all the getter/setter methods of ny User
Object so as to faciliate the CRUD operation from the browser.
If something changes I need to go and change it in both the places.
Is there any way to over come this problem.
Any help would be greatly appreciated.
