Initialize Hibernate During Deployment
I followed the JBoss to
http://cwiki.apache.org/GMOxDOC20/jboss-to-geronimo-hibernate-migration.html
Geronimo Hibernate Migration to get Hibernate working in Geronimo, and it
works just great. My only problem is the first time I use Hibernate in my
web application, it has to initialize which takes about 2 minutes.
My question is, how do I get Geronimo to initialize Hibernate when I deploy
my WAR, or when the WAR starts up (when Geronimo is restarted). Has anyone
ever done this?
Thanks,
Patrick

Hmmm..... I would have hoped that this bit of documentation could
have discussed when you would use the standard jee listeners
available to any web app and when you would need a proprietary tomcat
extension accessed through a proprietary geronimo configuration
method. Basically unless you have to get into really deep geronimo
internals you are better off with the jee listeners configured in
your web.xml. If you have to use some geronimo internals you can
arrange to look up a gbean in jndi.

Hi David,
Thanks, that did work for me.
After your last post about listeners, I found this
http://publib.boulder.ibm.com/wasce/V2.0.0/en/lifecycle-listeners.html#Lifecyclelisteners-webapp
article about life cycle listeners, and I had a deploy error with the
<gbean> tags.
Your solution was app server independent and much easier to implement.
Thanks,
Patrick

I would think that if you included a load-on-startup element for one
of your servlets and called the static method in initialize() from
that servlet it would get called when the app is started? Maybe I'm
missing something obvious.

Hi David,
I do know what Hibernate is doing, it is reading the hibernate.cfg.xml file,
reading up the mapping files and creating a org.hibernate.SessionFactory.
All of this is in a static method in my HibernateUtil class. This is how
Hibernate works with other app servers (as far as I know).
What kind of listener do I need to create that gets triggered when the app
starts? This sounds like what I'm trying to do.

Do you have any idea what hibernate is doing? Does this happen on
other app servers?
If you can figure out what is triggering the initialization you might
be able to trigger it in a listener so it happens when the app starts.
thanks
