|EclipseLink Developing JAXB Applications Using EclipseLink
Beta Draft: 2013-02-28
When using EclipseLink MOXy as the JAXB provider, no metadata is required to convert your existing object model to XML or JSON. You can supply metadata (using annotations, XML, or JSON) only when fine-tuning of the XML or JSON representation is required.
EclipseLink MOXy includes many advanced mappings that allows you to handle complex XML structures without having to mirror the schema in the Java class model.
