Hi... I am trying to use validation annotation to achieve the following:
1. I have a Java bean "aBean" in my action class, and it has a java.util.List<AnItem> as its property. 2. AnItem has the structure as follow: AnItem{ private String name; private int quantity; ... // getter & setters } My question are as follow: - How can I perform validation on this Java bean? Say, I need "name" to be a required field. The only solution that I can think of, is to use @ExpressionValidator, which points to a method that do the validation programmatically. The same goes with "quantity"... it must be an integer - Complex validation that involves both "name" and "quantity". Say.. where "quantity" is specified, the "name" has to be specified as well. Again, the only solution I can think of is to use @ExpressionValidator Thanks in advance! -- Best regards, WiB -------------------
