BEYOND THE HYPE, IT'S ALL ABOUT INTEROPERABILITY
O'REILLY RELEASES "JAVA WEB SERVICES"


Sebastopol, CA--Just a few years back, there were many people who found
it difficult to describe what the Internet was. The problem was not
that they didn't understand it--because most of them were fairly clear
on the concept. The problem was coming up with the right words to draw
all the pieces together to convey the vision. Explaining the concept
of web services is equally challenging. Fortunately, the lack of clear
language to describe what web services precludes neither their
usefulness nor the ability of developers to deploy them. For Java
developers interested in learning what web services have to offer, the
new "Java Web Services" book by David A. Chappell and Tyler Jewell,
(O'Reilly, US $39.95) provides a detailed overview of web services,
XML-based interoperability technologies, and the Java technologies
designed to interact with them.

"Dave and I recognized that the Java community had a strong need to
understand how Java applications exist in a web services world. Web
services are key for doing application integration, but what does that
mean for those applications that are built using Java? We tried to
answer that question in this book," says Jewell.

Adds Chappell, "There is a great deal of hype and confusion out there
about how web services technology can be used. With a myriad of
evolving standards and technologies--some real and some not yet
baked--we felt it was important to do the investigative work to
determine what's viable now and what needs to mature. We believe that
our book provides some real-world clarity."

"Java Web Services" is a practical book loaded with working examples of
how each Java-based API can be used in real-world business-to-business
communications environments. Java developers will learn how to use SOAP
to perform remote method calls and message passing; how to use WSDL to
describe the interface to a web service or understand the interface of
someone else's service, and how to use UDDI to advertise, or publish,
and look up services in each local or global registry. The book also
discusses security and interoperability issues, integration with other
Java enterprise technologies such as EJB and JMS, the work being done
on JAXM and JAX-RPC packages, and interoperability with Microsoft's
.NET services.

"This material is critical to developers," says Jewell. "CIOs have
identified integration as their number one concern for the upcoming
years. Web services are the technology that will make integration
easier and cost effective. Developers who get on board with this
technology in its early stages are preparing themselves to be at the
forefront of the upcoming tidal wave."

Says Chappell, "CIOs and architects constantly hold up a now familiar
schematic and say, 'We've got to build one of these.' What they point
to is a new type of architecture that web services are addressing with
real technology today. Chances are that the companies the readers of
this book work for will have deployed a new CRM application, an
e-business initiative, supply chain management and ERP and system
during the last ten years of big IT spending, leaving the company with
islands of isolated application domains. While integrating these
systems stands to create significant operational efficiencies, until
now enterprise application integration, or EAI, solutions have been
prohibitively expensive, and thus sparingly implemented.

"That's about to change," Chappell adds. "Our book will give architects
and developers the proper foundation of knowledge to make informed
decisions about architecture and technology choices, and apply web
services concepts to current projects, as well as new deployments."

"Java Web Services" gives the experienced Java developer an entre into
the web services world by taking a broad look at the many emerging
Java-based approaches to working with web services. Although the web
services picture is still taking shape, the fit between the fundamental
principles on which Java and web services are based mean that Java will
almost certainly be the predominant language for web services
development. This book will help readers understand the core web
services specifications and immediately begin to use Java technologies
that integrate with them.
