TopLink also comes with an XML extension that allows you to easily read and write your objects from XML files. This extension is used by the TopLink Mapping Workbench to read and write your TopLink Projects.

You will also need to take advantage of a number of new TopLink mappings and use many of the customization hooks provided by TopLink that are not used by a “typical” TopLink application. The new mappings include: SDKAggregateObjectMapping SDKAggregateCollectionMapping SDKDirectCollectionMapping SDKObjectCollectionMapping The XML extension is a simple example of how to implement the classes required by the TopLink SDK to access a non-relational data store. By default, the XML extension reads and writes your objects from XML do
