T5 Hibernate and Hibernate Annotations
Hi all,
I am just getting started with Hibernate in my Tap 5 application, and
I'm kind of manually setting up Hibernate using the standard
HibernateUtils static methods and xml files for my domain objects. It
is working, although it's not elegant.
Now, I thought it would be good to explore this Hibernate-Annotations
[HA] library that is compatible with Hibernate 3.2+. It seems that
with this lib, I can set up Hibernate as well as set up the entity
objects (although the annotations in the Hibernate docs seem to come
from the javax.persistence.* package which is used for EJB3s), and rid
myself of xml set up files.
Now from the small snippet of code on Tapestry-Hibernate [TH5], I see
that you can do your Hibernate configuration there, and it will also
set up your entities. However, I don't know the full ambition of this
library--would it replace the need for HA?
Put another way,
If I was using TH5, do I need to have the .hbm.xml files for my
entities, or can I use HA, or is TH5 going to create the HA for me ?
I know this is alpha, an answer based on intended behavior is fine.

I have a running app with t5 and HA
if you follow a convention:
your.package.pages - pages
your.package.services - services and AppModule
your.package.entities
without any extra config besides connection data in hibernate.cfg.xml
your entities will be recognized.
you can do this by following the tutorial
http://tapestry.apache.org/tapestry5/t5-tutorial.pdf
and use quickstart archetype (whole comman in one line)
mvn archetype:create ↵
-DarchetypeGroupId=org.apache.tapestry ↵
-DarchetypeArtifactId=quickstart ↵
-DarchetypeVersion=5.0.4 ↵
-DgroupId=org.example ↵
-DartifactId=hilo ↵
-DpackageName=org.example.hilo
if you want to contribute other package do it via:
contributeHibernateSessionSource
since HibernateSessionSource service is responsible
for enumerating entities and adding them to Hconfig.
you can see it in HibernateSessionSourceImpl source
in org.apache.tapestry.hibernate.HibernateModule
you have an example of doing just that:
/**
* Contributes the package "<root>.entities" to the configuration,
so that it will be
* scanned for annotated entity classes.
*/
public static void
contributeHibernateSessionSource(Configuration<String> configuration,
ApplicationGlobals globals)
{
configuration.add(globals.getApplicationRootPackage() +
".entities");
}

Re: T5 Hibernate and Hibernate Annotations
Posted by Daniel Jue <te...@gmail.com>.
Thanks Davor,
I got it working, although it seems to require a
myentity.hbm.xml, specified via the hibernate.cfg.xml.
I was hoping I could use the @Entity, @Id, etc, annotations in my
entity classes instead. From the Hibernate docs, it seems like
enabling these "Hibernate Annotations" requires a special
instantiation of a hibernate session factory, which I am not sure if
Tapestry-Hibernate does at the moment--I'll have to dive into the
source when I have time.
In any case, it seems to work without problems.

HibernateSessionManager being internal means you shouldn't be
managing it your self.
it's ok to :
@Inject private HibernateSessionManager _sessionmanager;
but creating it manualy is not a good solution,
keep just the inject and tapestry ioc will provide it for you,

Re: T5 Hibernate and Hibernate Annotations
Posted by Daniel Jue <te...@gmail.com>.
Thanks Davor.
I think I'm going to use my domain POJOs as the "entities", and they
currently live in the package
myapp/model/domain
I think this should be ok, since EJB3 entities are POJOs, from what I've read.
So I will use that snippet of code to contribute the
myapp/model/domain package, and Tapestry should have it's way with the
pojos there.
In my page classes I want to do something like this:
@Inject private HibernateSessionManager _sessionmanager;
(I have a feeling I want the manager instead of just a session.)
Now, in my AppModule.java, I've added these things:
public void contributeEntityPackages(Configuration<String> configuration)
{
configuration.add("myapp.model.domain");
}
public HibernateSessionManager buildSessionManager()
{
return new HibernateSessionManagerImpl(new
HibernateSessionSourceImpl(null, null, null));
}
Besides the nulls, am I on the right track here, instantiating the
Tapestry Hibernate internal classes (impl classes are in a package
called Internal)?
I am unsure on how to fill in the constructor for HibernateSessionSourceImpl:
HibernateSessionSourceImpl(Log log, Collection<String> packageNames,
ClassNameLocator classNameLocator)
I thought i was specifying the package names in the
contributeEntityPackages method.
For classNameLocator I can just put new classNameLocator().
Alternatively, should I be creating a HibernateSessionSource through
bind, or is build* the way to go?
Thanks,
Daniel

Re: T5 Hibernate and Hibernate Annotations
Posted by Davor Hrg <hr...@gmail.com>.
you use HA along with t5,
t5 just supports it naturaly,
if you put the entities in the entities package t5 will find them
and add them to config.
then, all you need is hibernate.cfg.xml containing connection data
I'm leaving office right now so sory for a such short reply..
