This article, intended for CIOs, software/solutions developers, and system architects, covers design and usages of service-oriented architecture in the enterprise, discusses problems introduced by SOA, and provides an alternative approach to architecting such solutions by integrating a native XML operational data store. It also provides a specific use-case (hospital infrastructure) scenario and explains the benefits of the native XML approach. The approach discussed in this article will enable your enterprise applications to become more efficient, run faster, be standards-compliant, provide a single, accurate view of data, and reduce development and maintenance costs.

Web services versioning doesn't really exist. To achieve new versions of a service, you have to create a new set of WSDL/XSD files with new namespaces, essentially creating a new Web service. That's a rather drastic solution. There are some changes you can make to an existing set of WSDL and XSD files that are backward compatible so that you can evolve your service, to a limited degree, without the drastic measure of creating a new one.

http://www-106.ibm.com/developerworks/webservices/library/ws-tip-altdesign1/ - Oct, 2004 - Use a Java applet to access remote Web services by Nicholas Chase - [Clicks: 28]
Applets have always been designed to play in a "sandbox" in which they can't hurt anything on a user's system, so their security is tighter than that of their server-based application counterparts. For example, a Java application can easily make a network connection to another server to request a Web service response; an applet can, too -- as long as it's talking only to the server on which it was originally hosted. But what if you want an applet that can make arbitrary Web requests? This article shows you how to work around this problem by building a server-based proxy. It also shows you how to use JavaScript code to access applet-based information.

Today's Web services implementations are typically simple and often similar to a client-server model. However, platform-neutral interchange is supported, which allows a diverse range of client implementations to interact with new or legacy code as server functions. Much has been written about the technologies that make such applications straightforward to implement. It is now time to look at the bigger picture of what we can do with them. The author addresses the question of how to move forward from simple models to those that represent real-world business models of arbitrary complexity.
