Design Practice: Handling umpteen params in Action
Hi,
__Q1__
Say i have a form with 12 fields.
Submitted -> Request comes to Action.
I need to pass these form fields to the business logic class.
+ One way to do this is --call(p1,p2,p3,p4,p5.....)
+ Other way could be ----call(map of form fields)
Which one should be used?
__Q2__
test.jsp -> TestAction.java -> Test.java
Say i need a session value(set of session values) in Test.
In TestAction
+ One way to do this is --Test.call(session.getAttribute(..))
+ Other way is to prepare the map like composite object and pass it on.
Which one should be used?
Both the Qs seem to be primitive but most of us must have faced them like a
tough problem.
Any sugestions are welcome.

Third option is to create a DTO bean instead of using a map, that has
typesafe getters and setters for the stuff you need to pass to the business
logic class.
