Configuring top-level meta-objects for the data handler

Meta-objects are business objects that contain configuration information. A data handler meta-object contains information to configure a data handler. The connector uses the information in the data handler meta-object to create an instance of the XML data handler.

Before running the connector, you must set up a data handler meta-object that specifies what data handler the connector will use based on the MIME type. When the connector receives a business object request, it uses information from the meta-object to dynamically create an instance of the appropriate data handler.

The connector gets the name of the top-level data handler meta-object from the connector configuration property DataHandlerConfigMO. The top-level meta-object is a hierarchical business object that can contain any number of child objects. Each child object is a flat object that represents a specific data handler instance. Child meta-objects have attributes that provide configuration values that enable a data handler instance to do its work. Different types of data handlers require different configuration properties, so the child meta-objects that support specific handlers have different attributes.

The XML connector uses the XML data handler to convert between business objects and XML documents. To configure the XML data handler for the connector, do the following:

For detailed information on setting up meta-objects for individual data handlers, see the Data Handler Guide.

Note:
For the connector to instantiate a data handler, the data handler top-level meta-object must be part of the connector's supported objects list.
