Hi Maxime,
It should be possible to put the service.jar in the Tomcat lib/
directory without a persistence.xml in it and then include that
persistence xml in your webapp. You should be able to include a <jar-
file> element in the unit declaration that points to the C:/tomcat6/
lib/service.jar so all the entities will be discovered without having
to explicitly list them via the <class> element. You'd have to
include the same persistence.xml in each webapp that wanted to reuse
the classes in service.jar.
Not entirely sure though if that's really what you're after. We don't
currently have any support for "global" persistence units. Meaning
say a persistence unit declared outside of an ear at server level and
available to all ears/apps deployed. It might be something we could
add if that's really what you're after.

Hello everybody,
I am developping ejb-jar module (let's call it service.jar) which
contains
EJB, Entity, Service and persistence.xml (in META-INF).
I am developping webapp module (let's call it test.war) which contains
Servlets who are calling some Service in service.jar (using
entityManager to
persist some data).
I am trying to make this work under Tomcat 6.xx using OpenEJB 3.1
(build:
20081009-03:31).
A.jar is present in the common classloader of Tomcat (in lib
directory) in
order to be visible by all webapps.
In this case, during Tomcat starting, OpenEJB show the following
Error :
"ERROR - Unable to deploy collapsed ear in war /test: Exception:
Creating
application failed: C:\tomcat6\webapps\test: PersistenceUnit already
deployed: /C:/tomcat6/lib/service.jar"
If service.jar is present in the WEB-INF/lib of test.war, everything
works
well, but this is not I want (classes of service.jar should be
visible by
all webapps).
Do I miss something? Is this possible with OpenEJB?
I make several try and search but I do not find how to solve this
(and I am
a beginner in OpenEJB).
Thanks in advance, any help would be appreciated.
Maxime
