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.
