Web services (WS) are emerging as the technology for integrating loosely coupled applications employing three main protocols: WSDL (describing the WS), UDDI (publishing the WS), and SOAP (accessing the WS) using XML. WS could also be composed together to meet certain business requirements. Strategies for implementing WS include open source, such as XML and Java and product-based, such as Microsoft .NET. Each of these two strategies has advantages and disadvantages. Example of success stories of WS implementations will be given and analyzed. Potential applications of WS for intranet and internet platforms will be highlighted.
- Why we need WS
- Loosely coupled applications
- Definitions and basic concepts of web services: WSDL, UDDI, and SOAP
- Assembly/Composite web services
-WS implementation strategies:
- Standards-based:
- Open standards Java, XML
- Product-based .NET
- WS cases.
- WS applications
- Internet applications: virtual organizations, supply chain, and e-government,
- Intranet application.
- Organization's readiness for WS

The fast growing, and one of the most rapidly changing, instructional areas in IS is e-Commerce. A cursory examination of the needs for assistance posted on many mailing lists such ISWORLD, looking for textbooks and case studies to recommend, shows that academics around the world are still struggling with the demands inherent in teaching this not just hybrid but difficult subject . The critical need to address these fundamental concerns in teaching e-Commerce (e.g., what should one include in a first year e-Commerce module?) has become so pressing.
The primary objective of this workshop is to provide an opportunity for academics to carve up key information focusing on e-Commerce teaching, gathered from the conference participants through in-depth face-to-face discussions (i.e., in teaching contents and methodologies, teaching resources such as textbooks and journals used, difficulties encountered, and directions of the subject at both undergraduate and graduate levels). It is expected that this information will be valuable in advancing knowledge to academics that are involved in e- Commerce teaching not just in Asia but also throughout the globe.
