Hi all...
I am using Struts 2.0. Has anyone ever done validation on individual item in
java.util.List before?
Say, I have a property
List<Customer> customers
in my Action, and Customer is defined as:
public class Customer{
private String username; // must not be empty
private int age; // must be > 0
}
In the JSP I have the following:
<c:forEach begin="0" end="10" var="i">
<s:textfield key="customers[${i}].username" />
<s:textfield key="customers[${i}].age" />
</c:forEach>
How can I enforce using struts validation (preferrably through annotation)
so that:
- both username and age are compulsory
- age must be an integer
Secondly, since "age" is of type "int".. when user enter characters
(numbers) in the textfield, they get converted to 0 (somehow).
How can I prevent this?
Thanks in advance!
