The connector for JD Edwards OneWorld is metadata-driven. In the WebSphere business integration system, metadata is defined as application-specific information that describes a OneWorld application object's data structures. The metadata is used to construct business object definitions that the connector uses at runtime to build business objects.
After installing the connector, but before you can run it, you must create the business objects definitions. The business objects that the connector processes can have any name allowed by the integration broker. For information about naming conventions, see the Naming Components Guide.
A metadata-driven connector handles each business object that it supports according to the metadata encoded in the business object definition. This enables the connector to handle new or modified business object definitions without requiring modifications to the code. New objects are created in Business Object Designer, with or without the assistance of the ODA. To modify an existing object, use Business Object Designer directly (the ODA cannot be used to modify an existing business object).
Application-specific metadata includes the structure of the business object and the settings of its attribute properties. Actual data values for each business object are conveyed in message objects at run time.
The connector makes assumptions about the structure of its supported business objects, the relationships between parent and child business objects, and the format of the data. Therefore, it is important that the structure of the business object exactly mirror the structure defined for the corresponding JD Edwards OneWorld object or the adapter will not be able to process business objects correctly.
If you need to make changes to the business object structure, make them to the corresponding object in OneWorld and then run GenJava to create .jar files that can be used as an input into the ODA.
