Enterprise Application Integration (EAI) is the discipline of linking disparate applications, platforms, and operating systems to work as one -- and deliver powerful business results seamlessly. Platform-independent Java may be the most powerful EIA tool ever invented, but mechanisms are still needed to exchange data with non-Java applications. XML provides those mechanisms. This is the first complete guide to using Java and XML together to build real-world EIA solutions! First, review the basics of XML and how it can be used to build EAI infrastructure. Identify your requirements for sharing and exchanging data; then build Java applications for parsing and processing XML documents. Learn how to move data between Java and non-Java applications: serializing Java objects into XML; using XML with relational databases; asynchronous messaging with XML; and much more. The CD-ROM contains extensive source code from the book, plus a remarkable library of leading-edge software and trialware, including: Bluestone Visual-XML desktop XML development environment; IBM XML4J Java-based parser; Push-technologies SpiritWAVE2 implementation of the Java Messaging Service; and webMethods BizView realtime XML Query Language interpreter.
