UDDI (Universal Description, Discovery, and Integration) is fast becoming a standard for storing business processes available on the Web. Although UDDI is capable of storing many different types of data, for the purposes of this article I'll focus on how UDDI can be used to register We...
There's a common misconception that Business Process Execution Language for Web Services (BPEL) is useful only if all of your systems are Web services. This article describes how Web Services Invocation Framework (WSIF) enables BPEL to orchestrate nearly any legacy system as if it were...
Implementing industry standards for business processes can do far more than provide a common protocol for operations. Once commodity information or documents are standardized, it makes sense to look at what common actions need to be taken on that data or document - and standardize thos...
There is a need for container-managed support for local invocations among colocated Web services. This feature would be similar to EJB local invocations in the J2EE world.
Business is becoming increasingly virtual and decentralized, while real-time management of relationships with employees, contractors, partners, suppliers, and customers is becoming ever more crucial. Even within a single company, applications may reside on different platforms, in separ...
In recent years the application server has greatly evolved, expanding the set of core services provided by the infrastructure. The current Java platform supports XML data handling, scalability, load balancing, and other capabilities that allow application-level services to be developed...
As enterprises build a critical mass of Web services, they need some way of keeping track of those services. UDDI is an ideal store for such information. Using UDDI's built-in abstractions of business services, binding templates, and tModels referring to interface specifications, UDDI ...
Web portal software has emerged as one of the most important components of software enterprises over the last few years. That success has carried with it the challenge of how to integrate disparate software services into the portal - services that can live across multiple platforms, op...
In July 2003 a consortium of Web services vendors released the Web services Composite Application Framework (WS-CAF) to the community. WS-CAF is comprised of three specifications that together provide a means of reliably composing individual Web services into larger aggregate applicati...
When dealing with application integration, as you know by now, we are dealing with much complexity. The notion of ontologies helps the application integration architect prepare generalizations that make the problem domain more understandable.
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).
Over the past couple of years, several technology vendors have defined a comprehensive set of specifications that, when complete, will provide an infrastructure for enterprise-class Web services interoperability. The names of these specifications generally begin with 'WS-', so the grou...
As more enterprises move toward an e-business strategy, the communication and integration of disparate, heterogeneous applications and systems is key. Businesses must be able to securely connect and communicate with customers and trading partners alike.
Web services hold the promise to revolutionize the way architects build systems and how software is delivered and sold. While the full realization of these advances will take years to play out, most of these benefits are rooted in technologies that are available today. This article wil...
In the past two years, we have witnessed an explosion of Web services and XML communication technologies. While WSDL , SOAP, and UDDI have become the accepted bases of Web services, there are even more standards in the making.
Web services has the potential to transform e-business into a plug-and-play affair. Not only will Web services simplify how businesses interconnect, they will also enable businesses to find each other.
Web services has the potential to solve some of the most difficult technology and integration problems that have plagued IT departments for decades. Isolated systems, redundant code, extended development cycles, and vendor dependence have essentially been accepted as inherent side effe...
