org.jboss.seam.InstantiationException: Could not instantiate
Hi,
I'm a newbie to JSF/JBOSS/EJB3.0
I did the setup correctly and was able to load the jsp pages.
I created a Session Bean,entity bean and two xhtml pages.
When i try to enter the details and click submit button, i'm getting Instantiationexception when invoking the session bean.
Can anybody help me out.
SessionBean:
@Stateless
@Name("registerSessionBean")
public class RegisterSessionBean implements Register{
@In
private UsersImpl users;
@In
private EntityManager entityManager;
@Logger
private Log log;
public String register()
{
List query = entityManager.createQuery("select username from User where username=#{user.username}").getResultList();
if (query.size()==0)
{
entityManager.persist(users);
log.info("Registered new user #{users.username}");
return "/registered.xhtml";
}
else
{
FacesMessages.instance().add("User #{users.username} already exists");
return null;
}
}
}
LoginUser.xhtml
