Hello, I'm evaluating now SEAM framework as new Web development framework for
our project. I have some poblems using it.
I took the Logout stateful session bean as in booking example and separated the
db calls outside the ejb:
| public class ChangePasswordAction implements ChangePassword {
| @In(create=true)
| ChangePwdDao changePwdDao;
|
| public String changePassword()
| {
| if ( changePwdDao.changePassword()) {
| FacesMessages.instance().add("Password updated");
| return "main";
| }
| else
| {
| FacesMessages.instance().add("verify", "Re-enter new password");
| changePwdDao.cancel();
| return null;
| }
| }
In ChangePwdDao:
| @Scope(EVENT)
| @Name("changePwdDao")
| public class ChangePwdDao {
| @In @Out
| private User user;
| @PersistenceContext
| private EntityManager em;
| public boolean changePassword() {
| //using em here
| }
|
I receive NullPointerException while trying to use EntityManager inside the
dao. As I understand SEAM injects the user variable but doesn't inject em
(EntityManager).
I would like to see what's wrong with my code.
Thank you in advance.
