Overview
An adapter service defines an operation that the adapter performs on an adapter resource. Adapter services operate like Integration Server flow services or Java services. Adapter services have input and output signatures, can be invoked within flow services, and can be audited from the Integration Server's audit system.
Like a connection, an adapter service consists of a Java class component and a namespace node in which design time settings are stored in the metadata parameters. Adapter services support:
Basic metadata constructs supported by connections.
Additional data types.
More sophisticated widgets.
Ability to define the signature of the adapter service node.
This means that the users of the adapter can specify what data to search for in the flow service pipeline when the adapter service is called, and what data to place in the pipeline during the execution of the service. Using these signatures, you can link the adapter services to other Integration Server elements as part of a total integration solution.
Designer provides the facilities for the users of the adapter to create, configure, and test adapter service nodes.
