Outbound request processing

This topic describes the outbound request processing for the WebSphere® Adapter for Flat Files.

For outbound request processing, an external J2EE client can invoke the adapter through the Service Component Architecture (SCA). The client requests a connection, which in turn is passed from the adapter to the enterprise information system (EIS). Outbound support allows a client to make calls to the adapter to perform specific operations in an EIS file system.

Operations supported by outbound request processing mode include:
Outbound request processing consists of the following steps:
  1. The outbound service client looks up the business object factory service.
  2. The outbound service client creates a business object from the business object factory.
  3. The outbound service client locates the adapter service.
  4. The outbound service client invokes the appropriate function on the adapter service by passing the function name and the business object.
Note: The adapter supports only synchronous outbound communication and does not support asynchronous mode.

Parameter passing in the SCA framework

Using the service client, the user can pass protocol-specific parameters, such as the directory path and file name, in the following ways:

  1. Through the business object that is passed as a parameter while invoking the adapter service.
  2. The parameters can also be set in WebSphere Integration Developer while generating the service artifacts. The parameters passed through the business object will override these values. Both directory path and file name should be set together through one or both of the above ways.
