Jena does not provide any builtin tools for using an ontology as some form of database schema specification. If that's what you need that I think you will need to write that yourself. Jena SDB does allow you to *store* an ontology in a database, just like you can store any RDF data in a database but the database layout is fixed by SDB and is not specific to the ontology you store in it.
