Web ServicesWeb services include SOAP, Web Services Decription Language (WSDL), Universal Discovery and Description Interface (UDDI) and other developing standards. .NET and Java include frameworks and API to fully access and utilize these standards.Separation of Concerns in Web Service Implementations By Tieu Luu The principle of "separation of concerns" is much repeated in SOA circles... so why are transactional integrity, security, and business logic so often intermingled in SOA implementations? In this article, Tieu Luu shows how to use Spring to separate out security concerns in an Axis-based web service. Sep. 6, 2006 Playing Together Nicely: Getting REST and SOAP to Share Each Other's Toys By Jason R.

Mar. 24, 2004 Another Java Servlet Filter Most Web Applications Should Have By Jayson Falkner Adding to his previous must-have servlet filters, Jayson Falkner introduces another: one to activate client-side caching, so browsers won't re-request items they can just cache. Mar. 3, 2004 Security in Struts: User Delegation Made Possible By Werner Ramaekers Struts may not have an all-encompassing security scheme, but what it does offer is extensibility.

Andrew Anderson takes a look. Dec. 23, 2003 Creating Richer Hyperlinks with JSP Custom Tags By Amit Goel Gone are the days where one destination per link was enough. With mirroring, localization, and internationalization, your readers might want the choice of several different resources for any given link. Until XLink and XPointer are well-supported in browsers and authoring tools, most alternatives are clumsy. Amit Goel demonstrates a better approach by creating a custom JSP tag to control a dynamic menu of destination links. Apr. 30, 2003 Developing E-Business Interactions with JAXM By Nikhil Patil RPC-style web services are getting a lot of press, but sometimes transferring a document is more important than calling a remote procedure.
