  1. SOAP By Justin Thompson

  2. What is SOAP? • Originally stood for Simple Object Access Protocol • Created by vendors from Microsoft, Lotus, IBM, and others • Protocol for exchanging XML-based messages over computer networks • Lets you activate applications or objects within an application across the Internet • Forms the foundation layer web services stack

  3. Transport Methods • Uses application layer protocols as transport protocols such as SMTP and HTTP • XML was chosen as the standard message format because of its widespread use by major corporations and open source development efforts

  4. Some applications of SOAP • Business to business integration • Distributed applications • To enable XML web services

  5. Advantages • With HTTP it allows for easier communication behind proxies and firewalls than previous remote execution technology • Versatile enough to use different transport protocols. Standard is HTTP, but others are usable, such as SMTP • SOAP can be considered to be XML and HTTP combined to send messages over the Internet • It is not constrained by the application language or the platform

  6. Disadvantages • SOAP can be slower than competing middleware because of XML’s verbose format • When relying on HTTP the role of the interacting parties are fixed • Many implementations of SOAP limit the amount of data that can be sent
