Web services technologies are beginning to emerge as a defacto standard for integrating disparate applications and systems using open, XML-based standards. In addition to building web services interfaces to existing applications, there must also be a standard approach to connecting these web services together to form more meaningful business processes. In 2002, a number of new standards were in...

One of the fundamental requirements for solutions to succeed in the business-to-business e-commerce domain is the ability to integrate seamlessly or inter-operate with diverse systems. In other words, the services offered by a business should be easily accessible by any consumer or business using the Internet infrastructure and standard protocols. A framework is needed by which new E-services c...

Web services are an important paradigm in distributed application development. Currently, many businesses are seeking to convert their applications into web services because of its ability to promote interoperability among applications. As a number of web services increase, the process of discovering appropriate web services for consumption from user’s perspective gains importance. In this pape...

The software engineering discipline is experiencing a quick consolidation in the applications development activities and the use of technologies and methodologies of web-based programming. In the web services arena some oriented and based practices for the construction of large scale software applications (i.e., distributed information systems) are beginning to appear. The software development ...

Matchmaking is an important aspect of e-commerce interactions. Advanced matchmaking services require rich and flexible metadata that are not supported by currently available industry standard frameworks for e-commerce such as UDDI and ebXML. The semantic web initiative at W3C is gaining momentum and generating technologies and tools that might help bridge the gap between the current standard so...

Web service is the kernel and key to develop a new dynamic E-business application framework and the dynamic E-business is the goal of E-business development. This paper introduced several key techniques of XML, SOAP, WSDL and UDDI in Web services as well as the relationships between these techniques. And the SOA can meet the requirements of various kinds of E-business application framework. So ...

With current evolving technologies, there are significant strides in technologies that support distributed system automation in the electronic commerce domain. The autonomy and intelligence of software agents have greatly enhanced technologies that promote automation and enactment in the electronic commerce domain. Moreover, with the addition of scaleable service-oriented computing practices, n...

We have developed the ZENTURIO experiment management system for performance studies, parameter studies, and software testing of parallel applications on cluster and Grid architectures. In this paper we describe the design and implementation of ZENTURIO as a Web service-based distributed architecture. We highlight limitations of Web services for deployment on the Grid and propose solutions. Expe...

We believe a source of dynamic organizational processes poised for exponential growth is B2B electronic commerce. In addition to serving as aggregators of product information, all major electronic marketplaces (i2, Ariba, CommerceOne, et al.) are developing infrastructure for the sharing of business process definitions and the augmentation of inter-organizational workflows. XML frameworks for t...

Using standards like UDDI, WSDL, and SOAP, it is now possible to discover a Web service and determine the interface and message format that it understands. However, actually calling a Web service requires carefully studying its documentation and then writing special-purpose code to handle the service. There is not enough information provided in WSDL definitions to allow the generation of a user...
