Can�t instantiate... why?

Question

Why can�t I do something like this:
Class: User.java , this is my example model class, used with hibernate
public class User {
  private String login;
  // getters and setters
}Class: LoginBean.java, this is my ManagedBean
public class LoginBean {
  private User user;
  // getters and setters
}JSF: login.jsp , this is the jsp file that uses the UserBean class
<f:view>
  <h:form>
     Login: <h:inputText id="login" value="#{loginBean.user.login}"/>
  </h:form>
</f:view>
...Doing this gives me an
javax.faces.FacesException: Can't instantiate class ....
I think that it might help a lot if we could do something like this....!

Try keeping your managed bean in faces-confix.xml file
<managed-bean>
          <managed-bean-name>loginUser</managed-bean-name>
          <managed-bean-class>com.XXX.XXX.common.domain.LoginUser</managed-bean-class>
          <managed-bean-scope>session</managed-bean-scope>
     </managed-bean>
