I've working on an application right now using T4+hibernate+spring and have
0 problems with it. I didn't read all of the thread, but what problems were
you having?
I used the tapestry-spring.jar found here
http://wiki.apache.org/jakarta-tapestry/Tapestry4Spring I haven't tried
Howard's version yet
(http://howardlewisship.com/tapestry-javaforge/tapestry-spring/).
Some other tips are:
Use OpenSessionInViewFilter
http://wiki.apache.org/jakarta-tapestry/FrequentlyAskedQuestions/SpringHibernate
to prevent Lazy Loading exceptions.
Make sure you read the documentation for Spring's OpenSessionInViewFilter
carefully
http://www.springframework.org/docs/api/org/springframework/orm/hibernate/support/OpenSessionInViewFilter.html
I extended OpenSessionInViewFilter like this:
protected Session getSession(SessionFactory sessionFactory) throws
DataAccessResourceFailureException {
Session session = super.getSession(sessionFactory);
session.setFlushMode(FlushMode.AUTO);
return session;
}
protected void closeSession(Session session, SessionFactory
sessionFactory) {
session.flush();
super.closeSession(session, sessionFactory);
}
This prevents FlushMode.NONE exceptions, and prevents commits not showing up
in the database.

Hi Lutz,
| wow, this thread is really wandering off a bit... I will at least try
| to stick to the point.
That's right. But anyway very useful/interesting for many people as I'm
not
the only one struggling with problems as it seems. ;)
Let me describe what I did in the meanwhile:
I've set up everything _with Spring_ and at least I got further than using
Hivemind (means: For the first time Hibernate created the database tables!
jipii).
But even at this early point I think that Spring is very probably too
big for my needs... Well, as its not a big issue to switch back to
Hivemind (by just removing the tapestry-spring and spring jars and
re-enabling some hivemodule.xml configuration) I decided to try that.
Call me a masochist but now _I_ _just_ _want_ _to_ _know_ :)
Now, I'm using HiveTrans (as this seems to be the easiest solution)
and followed the documentation on
http://hivetranse.sourceforge.net/quickstart.html
I've put all necessary libraries under WEB-INF/lib but receive
the following error message, now:
---
