Today, developers are beginning to develop more sophisticated Web services, exchanging complex XML documents rather than simple parameter types. As this shift takes place, development teams begin to grapple with different approaches to designing these web services interfaces. Luckily, there are a number of best practices available for designing web services with XML Schemas and WSDL. For example: Using a modular schema design can maximize reuse of your Web services components, and can also simplify the process to map your interface to back-end implementation. The proper use of namespaces can simplify references to XML data types. They can also be used as a mechanism to enforce Web services versioning. The design should leverage the functionality of both XML Schema impo... (more)

Developing Web Services with Open Source - A quick start for Web services technology

Over the past year, Web services have been positioned as a key enabler to application e-business integration. Many companies and vendors have made large investments in supporting the Web services development process. However, cost can pose a huge barrier for companies just beginning to investigate the value of Web services. Development shops can explore this emerging technology without ma... (more)

JavaOne 2003

This year's JavaOne provided a good overview of the state of Web services today. This show report focuses on XML and Web services coverage at the event. Java and Web Services The J2EE community is working to better integrate Web services technologies into the platform. The J2EE 1.4 platform will provide a fully integrated Web services model, with support for SOAP 1.1, WSDL 1.1, and XML 1.... (more)

Using XML Schemas Effectively in WSDL Design

Developers are beginning to develop more sophisticated Web services, exchanging complex XML documents rather than simple parameter types. As this shift takes place, development teams begin to grapple with different approaches to designing these Web services interfaces through the use of WSDL. As we've worked with a number of these teams, we've begun to discover some important best practi... (more)

Design Strategies for Web Services Versioning

Application versioning has always been a challenge for the developer community. With the introduction of Web services, this issue becomes even more difficult as developers are dealing with a more distributed set of components that aren't necessarily under their control. A robust versioning strategy is needed to support multiple versions of Web services in development. This can allow for u... (more)
