Can I create a Managed bean myself and pass it to JSF?

Question

Hi,
Is it possible to create a managed bean in my code and pass it to JSF. I basically want JSF to take care of the data transfer from the request to the bean but I want to create and load the bean myself.
If that's possible would you mind leaving me some code example on how to pass it to JSF.
P.S.: I know that a managed bean is essentially an ordinary bean configure in the faces-config.xml as a managed bean. :)
Thx

(1)Why do you need manual instantiation of the 'managed' bean?I know such a case.
Suppose you already have an EJB application and want to use JSP to display the result of the EJB call which is returned as a JavaBean.
One solution is put your bean to SessionMap with the name specified in faces-config.xml.
FacesContext.getCurrentInstance().getExternalContext().getSessionMap().put("name", bean);
But, I hate this solution because it hard-codes the name of the bean.
My favorite solution is to provide the result bean as a property of another managed bean.
public class ManagedBean {
    private ResultBean result;
    public ResultBean getResult()  {return result;}
    public String action() {
        result = /* call EJB */;
         return "ok";
}Page authors can refer the result bean as #{managedBean.result}.
