Chapter 2: Web Services Technology Stack
Chapter 1 introduced you to SOA and BPEL – a language for composing web services. A composition of web services require several new considerations in protocol stack. Such collaborations require exchange of security tokens, transaction contexts, reliable delivery of messages, etc. Thus, the existing web services protocol stack must be modified to account for the additional information that must be carried as a part of the message.

In this chapter, you will study the modified protocol stack and the various new components added to the stack. Several new standards have been created for accommodating these components in the new stack. These are WS-Security, WS-Coordination, WS-AtomicTransaction, WS-businessActivity, WS-Reliable messaging, WS-Addressing, WS-Eventing, etc. You will study these new standards in the following sections.
