ingest

public void ingest()
            throws javax.xml.bind.JAXBException,
                   XMLStreamException,
                   Exception

This method will ingest the input data by reading in external DTOs in from the parser, instantiating project business objects, and inserting into database. Note that the XML Schema is organized such that object references are fully resolved. Therefore, there is no specific need to process the addresses as they come in. They can be stored once we get the accounts they are related to.

Throws:

javax.xml.bind.JAXBException

XMLStreamException

DAOException

Exception

createPerson

private void createPerson(Person personDTO)
                   throws DAOException

This method is called by the main ingest processing loop. The JAXB/StAX parser will already have the Person populated with internal property information.

Parameters:

personDTO -

Throws:

DAOException

createRegistration

private void createRegistration(VehicleRegistration registrationDTO)
                         throws Exception

This method is called by the main ingest processing loop. The JAXB/StAX parser will already have the VehicleRegistration populated with internal property information. The Person information for owners should also already exist.

Parameters:

registrationDTO -

Throws:

DAOException

Exception
