Course Overview
This instructor-led course enables Web services developers who are not familiar with B2B messaging standards to gain familiarity with the AS4 profile and the underlying ebMS 3.0 and WS-* specifications. Through a combination of lectures, discussions, and hands-on lab exercises, students will learn the fundamental aspects necessary to design and develop robust and interoperable implementations of the AS4 profile. Topics will include AS4 messaging semantics, Web services security such as XML Digital Signatures and Encryption, AS4 messaging choreographies, message receipts and business non-repudiation, reliable messaging, and error handling/reporting.

Objectives
After completing this course, students will be able to:
- Understand how the various layers of standards and specifications are composed that define the AS4 messaging standard including the AS4 Profile, ebMS 3.0, and various underlying Web services specifications such as SOAP and WS-Security
- Recognize and generate valid AS4 messages for a number of supported options and use cases
- Apply supported message and transport level security to AS4 messages including XML Digital Signatures, XML Encryption, SSL, HTTPS Client Authentication, and message pull channel authorization
- Recognize and generate valid AS4 message pull signal messages
