Web Services as the Holy Grail?
4/5/2004
|
In order for companies to benefit from the strategic value of information technology, there needs to be much closer alignment between IT and the business side. So far, these two counterparts have had a difficult time seeing eye to eye. The problem is that despite earnest intentions by both to work together, the application integration tools that IT has had to work with have been cumbersome.

XCP - the XML Control Protocol
4/3/2004
|
XCP - the XML Control Protocol - is a drop in replacement for traditional Transmission Control Protocol, or TCP. XCP has many advantages, some of which are outlined in our rationale section. With the advent of XCP/IP, connection-oriented networking will finally move from the legacy environment of inscrutable bits and bytes to a structured, human-readable world relying upon XML. XCP is the first 4th Generation Protocol, or 4GP. It is designed for a networking environment that is very fast and very reliable - the Internet of today!

Roundtrip issues in Java coding conventions
4/3/2004
|
Java APIs for XML-Based Remote Procedure Call's (JAX-RPC's) Java-to-WSDL/WSDL-to-Java mapping rules do not try to preserve Java constructs during roundtripping. Many constructs are preserved, but not all. This tip describes, in particular, why following Java coding conventions is very important to maintaining the ability to roundtrip.

VoiceXML 2.0 reaches W3C milestone
4/1/2004
|
While Microsoft touted the latest release of its SALT-based Speech Server at last week's SpeechTEK conference, a competing speech standard reached a milestone. The Voice Extensible Markup Language (VoiceXML) 2.0 received final 'recommendation' status from the World Wide Web Consortium (W3C). VoiceXML is the standard scripting language for rendering Web pages over the telephone. The decision of the W3C to advance VoiceXML 2.0, along with the supporting Speech Recognition Grammar Specification (SRGS), to recommendation status effectively establishes them as Web standards. It means that the standards group considers the spec to be stable and that it contributes to Web interoperability. It also means that the W3C membership favors its adoption by the industry.

XML tools: Who knows where or when?
4/1/2004
|
One of XML’s core strengths can also become a source of confusion. People have begun using the language for so many different things -- structured and unstructured content, app integration and workflow -- that the ways in which developers work with it vary widely. Some use XML-specific tools ranging from parsers to those that help with data transformation or integration, to content management software and workflow managers. Others opt for a fuller-figured XML development toolkit, analogous to an IDE. Some go the freeware route, or use text editors they already have, including emacs and vi.

Use wrappers and proxies for basic Web services tracking
3/30/2004
|
Some commercial Web services software provides sophisticated Web services accounting features, recording details of Web services transactions recognized on the wire. But sometimes developers need accounting that is more modular, much more basic, and available on a shoestring. This article explains how to use advanced function composition tasks to add basic Web services monitoring capabilities.

Web Services Metadata Exchange (WS-MetadataExchange)
3/30/2004
|
This paper explains how the Web Services MetadataExchange Framework is structured and how it operates. Web services use metadata to describe what other endpoints need to know to interact with them. Specifically, WS-Policy describes the capabilities, requirements, and general characteristics of Web services; WSDL describes abstract message operations, concrete network protocols, and endpoint addresses used by Web services; XML Schema describes the structure and contents of XML-based messages received and sent by Web services. To bootstrap communication with a Web service, this specification defines three request-response message pairs to retrieve these three types of metadata: one retrieves the WS-Policy associated with the receiving endpoint or with a given target namespace, another retrieves either the WSDL associated with the receiving endpoint or with a given target namespace, and a third retrieves the XML Schema with a given target namespace. Together these messages allow efficient, incremental retrieval of a Web service’s metadata.

Web Services Addressing: A new protocol for addressing messages in a distributed application environment
3/30/2004
|
Web Services Addressing (WS-Addressing) provides transport-neutral mechanisms to address Web services and messages. Specifically, this specification defines XML elements to identify Web services endpoints and to secure end-to-end endpoint identification in messages. This specification enables messaging systems to support message transmission through networks that include processing nodes such as endpoint managers, firewalls, and gateways in a transport-neutral manner. WS-Addressing defines two interoperable constructs that convey information that is typically provided by transport protocols and messaging systems. These constructs normalize this underlying information into a uniform format that can be processed independently of transport or application. The two constructs are endpoint references and message information headers.

WS-Security in real-world solutions
3/30/2004
|
Conducting business in today's world usually requires that a company use the Internet for both business-to-customer and business-to-business interactions. Information exchanged in business transactions is often mission-critical, market-valued, or confidential; thus, while traversing the Internet, it must be protected from accidental access or deliberate unauthorized control and use. Understanding the impact of how security options in a Service-Oriented Architecture (SOA) leverage Web services can enable you to make the best selection of security technology to address your requirements for authentications, data integrity, and confidentiality. Continuing from the previous article on Web services security, Part 2 of this article outlines WS-Security capabilities leveraged in real-world customer solutions with IBM® WebSphere® Application Server.

Writing Asynchronous, Bidirectional, Stateful, Reliable Web Services with Indigo
3/30/2004
|
Explores the attribute-based programming model provided by Indigo for writing Web services. Compares and contrasts the Indigo programming model with the ASP.NET Web services programming model, then walks through a series of code samples in which a synchronous, unreliable, request/reply, and stateless Web service is transformed to be asynchronous, reliable, bidirectional and stateful—all through attributes. The downloadable sample, written using Avalon, contains a client for the service.
