Channel Creations
After determining which adapter to use, you can create new channels for the
predefined and user-defined adapters. The channels that you create determine
how the adapter processes outbound integration messages.
Publish Channels
You can create publish channels in the Publish Channels application. When you
trigger publish channel processing, the integration framework message data
moves into the outbound queue. The message data is then transmitted to the
external system through the endpoint transport mechanism.
Object Structures
The object structure provides the XML message content for publish channel data
processing.
Publish Channel
Processing
You can provide a processing class, a user exit class, or an XSL map file, if
necessary, to map the XML to the external system XML. You also can implement
processing rules or Java classes for customized publish channel processing.
Processing Rules
The integration framework applies any specified processing rules to objects,
before it saves the objects. You can use processing rules to access and retrieve
pertinent data from objects that you do not include in the object structure.
Integration Controls
You can create an integration control when the predefined integration controls do
not meet your business needs. You can define integration controls globally and
associate them to a publish channel.
You can use integration controls to control the behavior of processing logic in a
Java class or in a processing rule. Control values are used in publish channel
implementations to meet your business requirements.
Interface Tables
If necessary, you can change the interface table name for the service or channel.
Invocation Channels
You can create an invocation channel in the Invocation Channels application. You
can use an object structure to define the data content of the invocation channel
message and its associated response. You can map the response message of the
external service to the response object structure of the invocation channel.
When you map a service to the response object structure, the message responses
can be passed to the caller of the external service. The message data is then
converted into the system input type by using the invocation channel response
processing class.
Object Structures
The request and response object structures are the basis for invocation channel
processing.
Invocation Channel
Processing
The invocation channel can perform a synchronous invocation of an external
service and can process the response of that service into the system. You can
define a processing class, a user exit class, or an XSL file, to map the object
structure XML to the external service XML. You also can apply processing to both
the service request configuration and service response configuration. If the
response data is not in the XML format of the object structure after the response
process runs, a processing error occurs.
