maybe it is a solution for you you not to use the persistence.xml at
all, as it can be overriden by the use of properties when creating the
emf. This would enable you to retreive the properties form outside the
bundle and put them into the emf. That way you could provide the
settings in a file outside the bundle jar. Im thinking of something like
// retrive the the properties-file from somwhere and load it
// hand it over to the emf, which will override the settings in the
Properties props = loadFromExternalFile();
I think most of the configs can be overriden using the
.... and so on.
