Overview

The JAXBHelperContext is a bridge between POJOs and SDO DataObjects. The bridge is based on their corresponding XML representations. For the POJOs the XML representation is specified using JAXB annotations or object-to-XML mappings.

Create the JAXBHelperContext

The JAXBHelperContext is instantiated using a JAXBContext. This JAXBContext represents the object-to-XML mapping for the POJOs. If static DataObjects are being used, a second constructor is offered that takes a ClassLoader as a parameter.
