The Metadata Model for Polling Notifications
The metadata model for polling notifications is identical to the model for adapter services, except for the following:
A polling notification has no input signature. The output signature is constructed in the same way, but the server uses it to generate a document type node that enables triggers to identify notification data in the node.
You register polling notifications in the WmAdapter.fillAdapterTypeInfo method instead of WmManagedConnectionFactory.fillResourceAdapterMetadataInfo.
