Faces Event > EJBTransactionRolledbackException > @In attribute requires non-null value
Hi
I am following the examples from seam in action (www.manning.com/dallen) and am using an ear deployment instead of war.
What I have here is a simple registration example, that used faces events to validate a field when an event is raised, like tab over the field.
In summary, the main difference is that I am deploying this in an ear and I am not sure why this error is occuring - I have
looked in the formums and tried adding this to the action, but nothing has worked:
@In(create = true,required=true) protected PasswordBean passwordBean = new PasswordBean();
RegisterBean
@Stateless
@Name("register")
public class RegisterBean implements Register {
@Logger
private Log log;
@In
StatusMessages statusMessages;
@In
private Member newMember;
@PersistenceContext
private EntityManager entityManager;
@In
protected MemberValidator memberValidator;
@In
protected PasswordManager passwordManager;
@In(create = true,required=true)
protected PasswordBean passwordBean = new PasswordBean();
@In
private FacesMessages facesMessages;
public String register() {
...
return "success";
}
public boolean isUsernameAvailable(String username) {
log.info("Checking if username is available " + username);
return entityManager.createQuery(
"select m from Member m where m.username = :username")
.setParameter("username", username)
.getResultList().size() == 0;
}
public boolean isEmailRegistered(String email) {
return entityManager.createQuery(
"select m from Member m where m.email = :email")
.setParameter("email", email)
.getResultList().size() > 0;
}
public void verifyUsernameAvailable(ValueChangeEvent e) {
String username = (String) e.getNewValue();
if (!isUsernameAvailable(username)) {
facesMessages.addToControl(e.getComponent().getId(),
"Sorry, username already taken");
}
}
public void checkEmailRegistered(ValueChangeEvent e) {
String email = (String) e.getNewValue();
if (isEmailRegistered(email)) {
facesMessages.addToControl(e.getComponent().getId(),
"Sorry, email address is already registered");
}
}
}
