Hi friends. I was wondering if there is some API which I am able to do this:
look at this example: public class Student { private Long Id = null; private String firstName; private String lastName; . . . constructors, getters and setters . . . public String toString() { return lastName + ", " + firstName } } I want to set for example "firstName" and "lastName" properties required, that if there is not data in them, then throwing an exception: I do that mechanically like: (look at the isReadyToSave() method) public class Student { private Long Id = null; private String firstName; private String lastName; . . . constructors, getters and setters . . . public boolean isReadyToSave() { return firstName != null && lastName != null; } public String toString() { return lastName + ", " + firstName } } I dont know, something like public class Student { private Long Id = null; @RequiredField private String firstName; @RequiredField private String lastName; . . . constructors, getters and setters . . . public String toString() { return lastName + ", " + firstName } } anyone knows something like that???????????? thanks. --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "Java EE (J2EE) Programming with Passion!" group.
