It's not altogether clear from the spec, but...(IIRC)
- if you set excludeUnlistedClasses in persistence.xml then we're
supposed to ignore any jar file urls
- if you don't set excludeUnlistedClasses we're supposed to ignore
any class names you provide and rely completely on scanning all jar
files listed to find the classes to enhance.
Again IIRC openjpa had some major problems dealing with listed
classes if you supplied both.

Hi,
I'm still trying to figure out why geronimo refuses seam's jee5 sample
to deploy and stumbled upon
org.apache.geronimo.persistence.builder.PersistenceUnitBuilder.respect
ExcludeUnlistedClasses(GBeanData
gbeanData) method.
private void respectExcludeUnlistedClasses(GBeanData gbeanData) {
boolean excludeUnlistedClasses = (Boolean)
gbeanData.getAttribute("excludeUnlistedClasses");
if (excludeUnlistedClasses) {
gbeanData.clearAttribute("jarFileUrls");
} else {
gbeanData.clearAttribute("managedClassNames");
}
}
Why is this for and how could I set the attribute
excludeUnlistedClasses?
it's in persistence.xml
I think I'm missing some Geronimo architectural design lessons so it
may seem obvious for the most if not all of you, but can't answer it
myself. If Geronimo starts a gbean, can its attributes be changed at
runtime?
yes, but if the attributes were supplied in the constructor nothing
will happen until you restart the gbean.
Am I allowed to deploy a gbean that's already deployed and
change its configuration, i.e. deploy a new configuration whereas the
former's removed.
I don't follow what you mean here.
BTW, is this app using Hibernate rather than OpenJpa? I don't know
what might happen from openejb's use of openjpa for cmp 2.1, but you
might try turning off the openjpa module. This should prevent the
openjpa enhancer from getting registered, and if its not registered
it can't cause trouble :-) If openejb turns openjpa on again for you
through dependency relationships you might be able to just turn off
the openjpa enhancer gbean.
hope this helps
