Passing SOAP messages with attachments through the service integration bus

The service integration technologies support web services that use a SOAP binding to pass attachments in a MIME message.

See the restrictions detailed in Limitations in the support for SOAP with attachments.

The service integration bus supports SOAP messages containing either old-style attachments (as described in the SOAP Messages with Attachments W3C Note) or attachments that use the Web Services-Interoperability (WS-I) Attachments Profile v1.0 (subject to the Limitations in the support for SOAP with attachments).

Attachments are carried through the service integration bus and passed to the inbound or outbound service. The content MIME type of each attachment is preserved. When the external target service for an outbound service is deployed to a Java API for XML-based Remote Procedure Call (JAX-RPC) compliant server, we can access the attachments on the target service using the javax.activation.DataHandler handler.

If the bus receives a message containing attachments, and the bus subsequently rewrites the message, then the generated message uses the same attachmentstyle as the received message. To transform attachments from onestyle to another, we can use a mediation to modify the message.
