[jboss-user] [JBoss Seam] - Using s:convertEntity with Hibernate and no EJB

I am using Seam 2.0 CR2 with Jboss 4.2.  Our application is a simple web application that is deployed as a WAR file and uses Hibernate for persistence.   My questions are:

1.  Can i use the s:convertEntity tag if i am using simple Hibernate for my persistence in a WAR file (i.e. no EJB stuff)?
2.  If so, how?  Or where is a good example of this?  Or where is this documented?

I have tried to follow the directions in the PDF documentation (sections 8.2 and the tag reference), but i get  the following exception, when i access the web page.

java.lang.ClassCastException: org.jboss.seam.persistence.HibernateSessionProxy cannot be cast to javax.persistence.EntityManager

My components.xml file snippet looks like this:
  <persistence:hibernate-session-factory name="hibernateSessionFactory"/>
  | 
  |   <persistence:managed-hibernate-session name="netkeySession" 
  |                             session-factory="#{hibernateSessionFactory}" auto-create="true"/>
  |   
  |   <transaction:hibernate-transaction session="#{netkeySession}"/>
  |        
  |   <component name="org.jboss.seam.ui.EntityConverter">
  |      <property name="entityManager">#{netkeySession}</property>
  |    </component>

I am pretty sure that the EntityConverter component is not correct, b/c the HibernateSession cannot be the entityManager, but i couldn't figure out what to put there instead.

Any help or pointers would be greatly appreciated,

thx
