I'm using NHibernate 3.2 and the JetDriver recompiled with a fix:
http://groups.google.com/group/nhusers/browse_thread/thread/dac170338846670d/82256971503a8e9d?hl=en&lnk=gst&q=jet#82256971503a8e9d
Here is my xml configuration:
<hibernate-configuration xmlns="urn:nhibernate-configuration-2.2">
<session-factory>
<property name="dialect">NHibernate.JetDriver.JetDialect,
NHibernate.JetDriver</property>
<property name="current_session_context_class">web</property>
</session-factory>
</hibernate-configuration>
You have to set the database path at runtime (or hardcode the full path
in xml, but in my case doesn't help).
Let us know if you have any problem
