What is WSIT?
Sun is working closely with Microsoft to ensure interoperability of web services enterprise technologies such as message optimization, reliable messaging, and security. The initial release of WSIT is a product of this joint effort. WSIT is an implementation of a number of open web services specifications to support enterprise features. In addition to message optimization, reliable messaging, and security,WSIT includes a bootstrapping and configuration technology. Figure 1–1 shows the underlying services that were implemented for each technology.

Starting with the core XML support currently built into the Java platform, WSIT uses or extends existing features and adds new support for interoperable web services. See the following sections for an overview of each feature:

• Bootstrapping and Configuration (page 3)
• Message Optimization Technology (page 4)
• Reliable Messaging Technology (page 5)
• Security Technology (page 6)
