This is expected. The "serialized" SessionFactory is in fact just a name; it doesn't serialize the whole state. You need to rebuild the factory if you restart.

---------------------------------------------------------------------
        Key: HB-178
    Summary: Serialization of SessionFactory fails with Tomcat context reload
       Type: Bug

     Status: Closed
   Priority: Major
 Resolution: REJECTED

    Project: Hibernate2
 Components: 
             core
   Fix Fors:
             2.0.2
   Versions:
             2.0.1

    Updated: Tue, 26 Aug 2003 1:36 PM
Environment: Linux, Tomcat 4.1.24, JDK 1.4.1, tested with current CVS

Description:
When Tomcat reloads an app context, the SessionFactory and its Sessions are loaded from the HttpSession files. I thought this would be fixed with the "null" in the UUIDGenerator fix, but it still throws an Exception on context restart. Everything else works fine, so no showstopper.
