Hi,
thank you for your time, but I still have more questions...
e) Are the [...]Module classes to be placed in the services package in the
Tapestry app module?
f) Is the naming important? Or could I have a FooModule class without having a
Foo module?
And another topic has arisen, which leads me back to b):
b.2) I've had the persistence.xml placed in the dao-hibernate module,
under src/main/java/META-INF/persistence.xml.
When I started the application and want to fill the database, no entity manager
can be found.
Error: " Unable to locate a single EntityManager. You must provide the
persistence unit name as defined in the persistence.xml using the
@PersistenceContext annotation."
I only have one persistence unit defined: "appUnit".
Each of my DAO classes is basically doing this:
@PersistenceContext(unitName="appUnit")
private EntityManager em;
public GlobalDAOImpl(final EntityManager newEm) {
this.em = newEm;
}
Am I doing something wrong here? Or should the persistence.xml be in a
different place?
Regards,
Daniel P.

Yep it's correct and no, there isn't any order.
Each of your modules should have its own ModuleNameModule class. This class
should contain a "public static void bind(ServiceBinder binder)" method where
services are bound to the tapestry registry.
An implementation of service should have a constructor where parameters are
other services you want to inject in order to use them (and optionally the
contribution parameter).
