Mediation primitives let you change the format, content or target
of service requests.
Introduction
Subtopics
Business Object Map mediation primitive
Use the Business Object Map mediation primitive to transform
messages. You can define message transformations graphically, using
a business object map.
Data Handler mediation primitive
Use the Data Handler mediation primitive to transform part
of a message. The Data Handler primitive is used to convert an element
of a message from a physical format to a logical structure, or from
a logical structure to a physical format.
Endpoint Lookup mediation primitive
Use the Endpoint Lookup mediation primitive to dynamically
route messages to appropriate service endpoints. The Endpoint Lookup
searches for service information in a WebSphere® Service Registry and Repository
(WSRR).
Event Emitter mediation primitive
Use the Event Emitter mediation primitive to emit significant
business events from inside a mediation flow.
Fail mediation primitive
Use the Fail mediation primitive to stop a mediation flow, and
generate an exception.
Fan Out mediation primitive
Use the Fan Out mediation primitive to create different
messages from a repeating element in the input message. Also, use
the Fan Out mediation primitive, together with the Fan In mediation
primitive, to aggregate (combine) service responses.
Message Logger mediation primitive
Use the Message Logger mediation primitive to store messages
in a relational database. Alternatively, you can use the custom logging
functionality to write to other storage mediums.
Policy Resolution mediation primitive
Use the Policy Resolution mediation primitive to dynamically
configure a mediation flow, using mediation policies. Mediation policy
information is obtained from WebSphere Service
Registry and Repository (WSRR).
Service Invoke mediation primitive
Use the Service Invoke mediation primitive to call a service
from inside a mediation flow. If the service returns a fault, you
can retry the same service or call another service.
Set Message Type mediation primitive
Use the Set Message Type mediation primitive to overlay
message fields with more detailed structures. You can then manipulate
message content more easily.
