There has been much debate lately on what exactly WSDL's purpose is, and much of that debate has focused on whether WSDL is an interface definition language (IDL), or whether WSDL is better used to specify message-level contracts (without any associated operational semantics). I... (more)

Object-oriented technologies are used today in the design and development processes for many computer systems; it is a proven paradigm and has made possible the development of large and complex software systems. Enabling platforms and tools for building and consuming Web services... (more)

Web services have become the integration platform of choice for enterprise applications. Those applications by the very nature of their enterprise-scale components can be complex in structure, which is compounded by the need to share common data or context across business process... (more)

With the emergence of Web services into the mainstream the developer has to learn how to architect and build service-oriented systems. While service orientation isn't a new concept, the rapid convergence of the industry on Web services technology has brought the concept of servic... (more)

In July 2002, BEA, IBM, and Microsoft released a trio of specifications designed to support business transactions over Web services. These specifications, BPEL4WS, WS-Transaction, and WS-Coordination (see WSJ, Vol. 3, issues 5-7), form the bedrock for reliably choreographing Web ... (more)

In part 1 of this article (WSJ, Vol. 2, issue 10), you saw how simply BTP toolkits can support the creation of applications that drive transactional Web services with consummate ease. This article covers the other side of the story: how the same technology impacts Web services de... (more)

It's a fact: Web services have started to mature. Those emergent standards that once held so much promise are now actually starting to deliver useful implementations. With the basic Web services plumbing mastered, we're starting to see more advanced infrastructure, which enables ... (more)
