  1. SOAP and WSDL CSCI 4300

  2. Simple SOAP message

  3. SOAP headers and body Headers: • Security credentials • Transaction IDS • Routing instructions • Payment tokens • Etc. etc. Body: • Actual message content

  4. Application-specific header example

  5. A security header

  6. Processing SOAP messages • In particular, JAX-RPC implements remote procedure calls by exchanging SOAP messages

  7. Modular processing

  8. Message passing: multiple actors

  9. Who processes the headers? • A node which has identified itself with this processing role will process this header.

  10. SOAP use case

  11. Sequential processing • Processing nodes can add and remove headers • The Inventory node can add an authentication header and force the next node to process it

  12. Web Services Description Language

  13. “portType”: a service access point

  14. Operation types

  15. WSDL – SOAP binding • The binding determines the format of the SOAP message that will transport a service
