For SOAP-based Web services, several advantages
exist if you use the SOAP nodes and the SOAP message domain instead
of the HTTP transport nodes and XMLNSC message domain.
- Support for WS-Addressing, WS-Security and SOAP headers.
- A common SOAP logical tree format, independent of the bitstream
format.
- Runtime checking against WSDL.
- Automatic processing of SOAP with Attachments (SwA).
- Automatic processing of Message Transmission Optimization Mechanism
(MTOM).
Although the HTTP nodes can process SwA messages, you must use
the MIME message domain and design your flow to handle the attachments
explicitly, and use custom logic to extract and parse the SOAP.
Cases where it might be better to use HTTP nodes include:
- Message flows that interact with Web services that use different
standards, such as REST or XML-RPC.
- Message flows that never use WS-Addressing, WS-Security, SwA, or MTOM.
