This is similar to code in my "Model 2" controller servlet, when I want it to
enforce the existence of a session. The only difference is that I use
RequestDispatcher.forward() instead, because it's faster.

Because you are not setting the "session" attribute, the default value (true)
should say that this page participates in sessions.

This should work. I've often seen this syntax as well:
<jsp:useBean id="registrationFormBean" scope="session"
class="com.evolution.examples.RegistrationFormBean">
<jsp:setProperty name="registrationFormBean" property="*"/>
</jsp:useBean>
as described in Section 2.13.1 of the JSP 1.1 spec. It is used in the case
where you want the properties set only if the bean is created by this call.

OK, now what failure symptoms are you seeing?
