DataNucleus supports persisting/retrieving objects to/from XML documents
(using the datanucleus-xml plugin).
It makes use of JAXB.
If you wish to help out in this effort either by contributing or by sponsoring particular
functionality please contact us via the DataNucleus Forum.
DataNucleus supports file-based XML storage currently.
The following persistence properties will connect to a local file on your local machine
replacing "myfile.xml" with your filename, which can be absolute or relative
So you create your PersistenceManagerFactory or
EntityManagerFactory with these properties.
Thereafter you have the full power of the JDO or JPA APIs at your disposal, for your
Access Platform allows you to query the objects in the datastore using the following
JDOQL - language based around the objects that are persisted and
using Java-type syntax
JPQL - language based around the objects that are persisted and
using SQL-like syntax
The following are known limitations of the current implementation
Application identity is supported but can only have 1 PK field and must be a String.
This is a limitation of JAXB
Persistent properties are not supported, only persistent fields
