No. You class operations would have DynaBean as the argument
and you would access the values using its public methods
get() and set().
For example, let's say I have a form bean defined in struts
called MyDynaForm which extends DynaValidatorActionForm.
Let's also suppose I have a service delegate called
MyService which has an operation called doSomething
which takes a DynaBean as an argument.
In the XXXXAction class:
DynaBean args = (DynaBean) form;
MyService service = //get service
service.doSomething(args);
Inside MyService.doSomething:
public void doSomething(DynaBean args) throws SomeException {
String email = args.get("email");
String userName = args.get("userName");
// do logic
// populate args with data
Collection someData = // get some data
args.set("data", someData);
}
There is a loose coupling because MyService must know
the property names of the DynaBean argument. This is not much
different that MyService using a concrete API to extract
data. It's just that one is validated at compile time and
one is validated at run time.
