Viewed from the enterprise perspective, Service-Oriented Architecture (SOA) is a framework for describing and managing business and IT assets, including services. At the implementation end of the SOA continuum, the architecture groups software-based services that can be loosely coupled into one or more functioning applications. Often, however, organizations find it difficult to link the enterprise concept to workable solutions. For many, the purpose of SOA is to implement IT solutions that achie...

What can I tell you about the attributes of the perfect application for a Grid environment? Or, should you be asking about the perfect Grid environment for your application? As much as you would like these two questions to lead you to the same answer, they rarely, if ever, do. In this article, I will discuss what I like to call the Application Grid—the perfect Grid setup for your application. I am staying away from the term "virtualization" because it is too abstract, and means different things ...

On this site, I have covered different topics on Axis2 that go from an introduction to Axis2 to very advanced tasks with Axis2, such as data services with Axis2. In this article, I am not going to discuss how to use Axis2 in simple applications or writing a service using Axis2; for that, I would recommend you to follow a few previous articles. The main goal of this article is to explain how to deploy or integrate Axis2 into an existing application....

The key appeal to the enterprise of purchasing portal products is the standards-based frameworks they provide. The common frameworks across provided by (almost) all vendors include navigation, administration, events, and security. Anyone who has built custom applications without these frameworks knows that what initially seems simple (or at least straightforward) will be wrought with many unforeseen pitfalls that lead to missed milestone dates and/or production nightmares. Assembling all of thes...

Let's face it. Providing sensitive information on a Web site is a risk. Many visitors will not give out that kind of data even if they see that the Web site claims security. Many more will certainly not reveal their personal details if the warm-and-fuzzy closed padlock isn't visible in their browser window. See the What's New section for the latest updates. Enter Secure Sockets Layer. SSL is a developer's tool for securing the transmission of data. Whether you are encrypting pages for the checko...

Once a Web Service has been deployed, potential users must be able to discover where it is and how it works. DISCO is a Microsoft® technology for publishing and discovering Web Services. Universal Description, Discovery, and Integration (UDDI) is an industry-wide initiative that defines a SOAP-based protocol for updating and querying Web Service information repositories. Like DISCO, UDDI makes it possible to publish and discover a Web Service, maximizing the site's reach and ultimate success. Th...

Web services are first and foremost about messages. No matter what platform you are using, what industry you are building services for, or what levels of complexity are available in your Web services stack, it all comes back to messages. When you are developing services or their corresponding clients, you are creating, transporting, and processing XML messages. Because tools try to make that process easy, sometimes you might (conveniently) forget what it's really all about. No matter how good yo...

The next major release of Microsoft Office SharePoint Server (MOSS), including Windows® SharePoint® Services (WSS) version 3.O, is fast approaching release. As with previous versions, WSS supplies out-of-the-box collaboration features that make it simple for users to create and design Web sites with shared elements such as calendars, contacts lists, and document libraries. But WSS is far more than a collaboration tool for end users. It is a full-fledged development platform that adds tremendous ...

Direct Internet Message Encapsulation (DIME) is a new specification for sending and receiving SOAP messages along with additional attachments, like binary files, XML fragments, and even other SOAP messages, using standard transport protocols like HTTP. In this article, the author explains what DIME is and how it differs from MIME encapsulation. A detailed description of the message format and how it is parsed, as well as working with SOAP and extending it with WSDL, is also included....

I just converted my application to ASP.NET. All the middle-tier components return XmlDocuments. I'm planning to create Web Services for most of the components. How can I avoid making any further changes to the middle-tier components in the process? If you're just interested in the XML contents of the document, you should type your Web methods as XmlElement and return the XmlDocument's DocumentElement property. This will serialize the XML document from the root node, skipping the document declara...

The ASP.NET WebMethod framework makes it possible to build XML-based Web Services that communicate over HTTP. It accomplishes this by mapping a pair of SOAP messages—one for the request and another for the response—to traditional remote procedure call (RPC) invocations. This is the only mechanism provided by the Microsoft® .NET Framework for building Web Services without resorting to writing most of the SOAP infrastructure yourself (which would require writing a custom HTTP handler, for instance...
