Java 2EE and XML development

Geared toward experienced developers, this reference demonstrates how Java 2 Platform, Enterprise Edition (J2EE), and XML technologies can be used together to create more robust distributed applications and software systems. The use of XML technology to extend and enhance the capabilities of the J2EE platform is covered in detail. Discussed are J2EE and XML integration at each layer of an n-tier distributed application model. Design patterns, tradeoffs, and decision criteria are provided in terms of individual XML and J2EE technology combinations. Hot topics in application integration are also covered, including Web services, architectures, and business partner integration.

software systems. The book also covers topics in application integration such as web services architectures and business partner integration. Explains why and how to use XML to build J2EE applications, explores recent developments in Java and XML technology, and discusses the trade-offs of building a J2EE application with XML rather than with only J2EE. First of all, it is out of date. And, it is not enough for a developer to learn how to use XML in J2EE environment. Yes, it does have some sample code, but not enough.
