Programming Web Services With SOAP
The web services architecture provides a new way to think
about and implement application-to-application integration
and interoperability that makes the development platform
irrelevant. Two applications, regardless of operating
system, programming language, or any other technical
implementation detail, communicate using XML
messages over
open Internet protocols such as HTTP or SMTP. The Simple
Open Access Protocol (SOAP) is a specification that details
how to encode that information and has become the messaging
protocol of choice for Web services.
Programming Web Services with SOAP is a detailed guide to
using SOAP and other leading web services standards--WSDL
(Web Service Description Language), and UDDI (Universal
Description, Discovery, and Integration protocol). You'll
learn the concepts of the web services architecture and get
practical advice on building and deploying web services in
the enterprise.
This authoritative book decodes the standards, explaining
the concepts and implementation in a clear, concise style.
You'll also learn about the major toolkits for building and
deploying web services. Examples in Java, Perl, C#, and
Visual Basic illustrate the principles. Significant
applications developed using Java and Perl on the Apache
Tomcat web platform address real issues such as security,
debugging, and interoperability.
Covered topic areas include:
The Web Services Architecture
SOAP envelopes, headers, and encodings
WSDL and UDDI
Writing web services with Apache SOAP and Java
Writing web services with Perl's SOAP::Lite
Peer-to-peer (P2P) web services
Enterprise issues such as authentication, security, and
identity
Up-and-coming standards projects for web services
Programming Web Services with SOAP provides you with all the
information on the standards, protocols, and toolkits you'll
need to integrate information services with SOAP. You'll
find a solid core of information that will help you develop
individual Web services or discover new ways to integrate
core business processes across an enterprise.
