DataNucleus jars are OSGi bundles, and as such, can be deployed in an OSGi environment.
Being an OSGi environment care must be taken with respect to class-loading. In particular
the persistence property
datanucleus.primaryClassLoader
will need setting.
Please refer to the following guide(s) for assistance until a definitive guide can be
provided
An important thing to note : any dependent jar that is required by DataNucleus needs to be OSGi enabled.
By this we mean the jar needs to have the MANIFEST.MF file including
ExportPackage
for
the packages required by DataNucleus. Failure to have this will result in
ClassNotFoundException
when trying to load its classes.
Note that the
jdo-api.jar
that is included in the DataNucleus distribution is OSGi enabled.
Also the Geronimo "jpa" jar that is included in the DataNucleus distribution is OSGi enabled too.
