The following exception is thrown when hitting the Login page
(interestingly, the Start page is fine) - there is additional information
following it. The (emerging) application used to work before adding the
Hibernate integration.

I found http://blog.progs.be/?p=52 and followed the advice, but no luck.
VERY surprisingly, there are no ~~~ in server.log (also tried with a
breakpoint). I'm stumped.
public class AppModule {
static {
javassist.runtime.Desc.useContextClassLoader = true;
System.out.println("~~~~~~~~~~"); //this is not executed!
}
}
The Tapestry root package is correctly configured (and AppModule is in its
services subdirectory) - the few Tapestry pages, including the Login one,
used to work before adding Hibernate.
Javassist comes in the picture because Hibernate uses it as a bytecode
provider when under JBoss:
hibernate.cfg.xml:
<hibernate-configuration>
<session-factory>
<property name="hibernate.bytecode.provider">javassist</property>
So I know AppModule is not loaded (but is deployed, I checked).
And to clarify, I'm not deploying Hibernate or Javassist as part of my app,
they come with JBoss. (As a side note, I did try to use the latest Hibernate
but that ran into other conflicts with T5 which I'll post another time, for
now I'm trying with the packaged Hibernate).
I searched and again went through the T5 book to see if I need to do
anything special to get AppModule to be consided by Tapestry, but there's no
such mention, it seems it should be handled by
convention-over-configuration.
Help is very appreciated,
JL
