44 TopLink Components

Development Tools:

• The Mapping Workbench creates and manages the mapping metadata that describes the relationship between Java classes and relational tables.

• The Session Editor creates the sessions.xml file that describes how TopLink communicates with the datasource at runtime.

Runtime Tools:

• The Web Client provides a Web-based interface to interact with any TopLink ServerSession deployed on a particular server, such as OC4J.

• The Session Console tests descriptors, database connectivity, and database performance.

Class Libraries: The Foundation Library contains the TopLink API that is called by an application to retrieve and store Java objects. It also includes application server-specific CMP (container managed persistence) information and can be used during both development and runtime.
