Thank you Matthieu,
I did as you suggested and took a look into OC4J's documentation. There's a
way to do what you told me to do: in order to enable local classes'
classloading behavior for a Web application, one needs to configure it by
having the following tag in the application's orion-web.xml file:
<web-app-class-loader search-local-classes-first="true"/>
Now it seems to be doing what you suggested but I am experiencing the
following exception:
SEVERE: The application named, default, could not start due to an error.

internalErrorWhileTryingToInstantiate
SEVERE: Internal error raised trying to instantiate web-application: ode
defined in web site Default Web Site. The application named, default, could
not start due to an error.
[default:ode] - Exception creating EntityManagerFactory using
PersistenceProvider class
org.apache.openjpa.persistence.PersistenceProviderImpl for persistence unit
ode-dao.
I really don't get why it throws a ClassCastException when trying to cast
org.apache.openjpa.persistence.PersistenceProviderImpl to
javax.persistence.spi.PersistenceProvider. I checked the docs and verified
the source code that comes with the openjpa.jar library packaged with ODE
and I found out that PersistenceProviderImpl is defined to implement
javax.persistence.spi.PersistenceProvider.
Do you happen to have any more clues. Thanks in advance.
