What is the purpose of RequiredStringValidator annotation?

Answer»

This validation annotation checks that a String field is not empty (i.e. non-null with a length > 0).

public class Employee extends ActionSupport{   RequiredStringValidator(message = "Default message",    key = "i18n.key", shortCircuit = true, trim = true)   public String getName() {       return name;   }}
