Chapter 13: Web Service Enhancements

Overview

In the previous chapter, we looked at the specifications that make up the Global XML Architecture (GXA). Specifications without any implementation are pointless, so Microsoft has released the Web Service Enhancements (WSE) package, which implements five of the specifications.

In this chapter, we’ll look at the underlying structure of WSE and how it integrates with the Microsoft .NET Web services infrastructure. As you’ll soon see, WSE builds on what’s already in place to provide an initial implementation of WS-Attachments, WS- Referral, WS-Routing, WS-Security, and WS-Timestamp.

We’ll then take a look at WS-Attachments and the implementation of WS-Timestamp. In Chapter 14 we’ll look at the possibilities for routing and referral, and in Chapter 15 we’ll look at the security features that WS-Security offers.
