Hi Douglas
The HibernateAssembler source is in
.../fds2/resources/samples/assemblers/flex-messaging-dist-src.zip so you
can see what is going on.
In this case, I think the problem is that hibernate can't find your
"entity class" - this is the part of the huge stack trace which is
important:

Hi Jeff,
Thanks for your response. I'm sending this to both you and the list, as
it may be helpful to get this thread into the archive...

I have the JOTM .jars installed but didn't have the JOTM XML file for my
app in tomcat-root/conf/Catalina/localhost.
But I don't think that that's the problem. Here's why (2 reasons):
1. When I try to do something like this I typically try to approach it
in baby steps. In this case I first got a slightly modified version of
Marcel Boucher's Hibernate example to work. It works. (Yay!) But I also
didn't create a JOTM XML file for that project.
2. Just to be sure, I just created that file for my project and
restarted Tomcat. Still doesn't work. :-(

I've posted the entire log file at:
http://www.brightworks.com/localhost.2006-11-02.log
It's much more readable online than than it is when pasted into an
email. Obviously, there are other log files but this is the only one
that indicates a problem.

Where would I find that? I've explored the WEB-INF folder of my project
and it doesn't seem to be there...
Finally, let me tell you a bit about what I'm doing. An overview may
help you to help me. My goal is to create a sample
Cairngorm/FDMS/Hibernate app. This will help me learn, demonstrate my
competency to future clients/employers, and hopefully help others. I've
started with the MySQL sample Sakila database and used HibernateTools to
auto-generate the Java and Hibernate files. Now I'm trying to graft the
client-side code, and server side configs, from the Boucher example that
I already have working onto it. He uses an "employee" table. Sakila is a
DVD rental store DB and has an "actor" table that is quite similar. It
should be fairly easy (or at least doable :-) to display data from this
one table. Once I get that working I can renovate the client side into a
Cairngorm architecture and start using other tables. Yum. :-)
Thanks,
Douglas
