IBM developerWorks Newsletter - Web services Edition
September 2002

IBM's resource for developers.
http://www-106.ibm.com/developerworks/?nws-92
========================================================================

Greetings, developerWorks readers.

If we think about the evolution of Web services in 3 stages,
"Connection," "Security," and
"Enterprise," it's easy to determine how
far we've come, and where we need to go to achieve secure, reliable,
enterprise-ready Web services. The Connection phase includes many of
the technologies that we have come to associate with Web services ---
SOAP, UDDI, WSDL, etc. The Security phase includes technologies like
XML Digital Signature, XML Encryption, SAML and the new WS-Security
specification and roadmap. Finally, we come to the Enterprise phase
which includes Web services capabilities to address
transactions,
business processes,
 and management. On August 9th, IBM, Microsoft, and
BEA helped to usher in the Enterprise phase with 3 new specifications,
Business Process Execution Language for Web Services (BPEL4WS), WS-
Transaction, and WS-Coordination. In this newsletter, you'll find links
to these new specifications, as well as whitepapers, demos and articles
to help you get up to speed, and tools to enable your next steps.

You'll also find a link to the WebSphere and .NET Interoperability demo
illustrating Web services security and interoperability between the 2
platforms. You'll be able to take advantage of the two-part tutorial on
implementing Web services with the IBM Web Services Tool Kit. You'll
also find links to some of the latest efforts towards
standardization
and interoperability
 through OASIS and WS-I.

Enjoy!
Until next month,
The IBM developerWorks team

NEWS AND TECHNICAL ARTICLES | Automating business processes and
transactions in Web services; The Most Important Open-Source Project
You've (Probably) Never Heard Of; Microsoft, IBM, BEA Deliver Specs To
Take Web Services To Next Level

::: Automating business processes and transactions in Web services :::
The new Business Process Execution Language for Web Services, WS-
Transaction, and WS-Coordination specifications provide a comprehensive
business process automation framework that allows companies to leverage
the power and benefits of the Web Services Architecture to create and
automate business transactions. Here we present a high level executive
overview of what the three new specifications provide.
http://www-106.ibm.com/developerworks/library/ws-autobp/?nws-92

::: Business Process Execution Language for Web Services, Version 1.0 :::
The BPELWS specification defines a notation for specifying business
process behavior based on Web services. (Specification)
http://www-106.ibm.com/developerworks/library/ws-bpel/?nws-92

::: Web Services Coordination (WS-Coordination) :::
This specification (WS-Coordination) describes an extensible framework
for providing protocols that coordinate the actions of distributed
applications. Such coordination protocols are used to support a number
of applications, including those that need to reach consistent
agreement on the outcome of distributed transactions.
http://www-106.ibm.com/developerworks/library/ws-coor/?nws-92

::: Web Services Transaction (WS-Transaction) :::
This specification describes coordination types that are used with the
extensible coordination framework described in the WS-Coordination
specification. It defines two coordination types: Atomic Transaction
(AT) and Business Activity (BA). Developers can use either or both of
these coordination types when building applications that require
consistent agreement on the outcome of distributed activities.
http://www-106.ibm.com/developerworks/library/ws-transpec/?nws-92

::: Web Services Security Addendum :::
This document describes clarifications, enhancements, best practices,
and errata of the WS-Security specification.

TUTORIALS AND DEMOS | A Demonstration of Web Services Interoperability
Between the WebSphere and .Net Platforms; Implementing Web services
with the WSTK 3.2, Part 2

::: A Demonstration of Web Services Interoperability Between the
WebSphere and .Net Platforms  :::
Interoperability is one of the important success factors for Web
services. It takes on added importance as new Web services
specifications are proposed and initial implementations are created.
IBM and Microsoft have created a set of applications that demonstrate
sophisticated Web services interoperability between the WebSphere and .
Net platforms. This paper describes those applications with particular
attention to how the new proposed Web services standard, WS-Security,
was used to send signed, encrypted messages based on X.509v3
certificates. The technology used in the IBM versions of these
applications is available now in the IBM Web Services Toolkit Version
3.2.2.
http://www-106.ibm.com/developerworks/library/i-wasnet/?nws-92

::: Business processes: Understanding BPEL4WS, Part 1  :::
The recently released Business Process Execution Language for Web
Services (BPEL4WS) specification is positioned to become the Web
services standard for composition. It allows you to create complex
processes by creating and wiring together different activities that
can, for example, perform Web services invocations, manipulate data,
throw faults, or terminate a process. These activities may be nested
within structured activities that define how they may be run, such as
in sequence, or in parallel, or depending on certain conditions. This
series of articles aims to give readers an understanding of the
different components of the language, and teach them how to create
their own complete processes. The first part of the series will take
readers through creating their first simple process. Subsequent parts
will extend the example in different ways to illustrate and explain the
key parts of the language, including data manipulation, correlation,
fault handling, compensation, and the different structured activities
in BPEL4WS.
http://www-106.ibm.com/developerworks/library/ws-bpelcol1/?nws-92

::: Implementing Web services with the WSTK 3.2, Part 1 :::
A Web service is an interface that describes a collection of operations
that are network accessible through standardized XML messaging. IBM's
Web Services Toolkit for dynamic e-business (WSTK) is a collection of
preview technologies that allow you to start experimenting with Web
services. This is the first part of a tutorial designed to walk you
through the process of designing, deploying, and utilizing services
implemented with the Web Services Toolkit. (contains sample code)
http://www-106.ibm.com/developerworks/education/r-wstk32a.html?nws-92

::: Web Services Demo Collection :::
The Web services demonstration collection allows test-driving of Web
services applications that are built on open standards and that use IBM
tools and technologies. Each "demo" includes some or all of the
following elements: run time, documentation, and code.
http://www-106.ibm.com/developerworks/offers/wsdemos.html?nws-92

::: Implementing Web services with the WSTK 3.2, Part 2 :::
A Web service is an interface that describes a collection of operations

::: IBM VisualAge Smalltalk Web services Quick Tester  :::
Use this Web services client application to quickly and easily invoke
any available Web service via a simple HTML interface. Provide the URL
of a WSDL resource, and the tool constructs a user interface to enable
instant invocation of the operations described by the WSDL.
