Facelets and JSP...how to port JSP code.

[SOSELLA]

I have been considering moving to Facelets.  I have studied it and like
what I see.  One problem I see is how to port my JSP code into Facelets.
 By this I mean, in some of my pages, I have JSP code

<jsp:useBean id="foo" class="com.myapp.bean.fooClass" scope="session" />
<%
   if (!foo.isLoaded())
   {
      response.sendRedirect("login.jsf");
   }
%>


Does anyone know how you might port this?  I am open to design changes
as well.

Thanks!
