Index of XML standards
The world of XML is vast and growing, with a huge variety of standards and technologies that interact in complex ways. It can be difficult for beginners to navigate the most important aspects of XML, and for users to keep track of new entries and changes in the space. XML is a basic syntax upon which you develop local and global vocabularies. This index provides a detailed cross-reference of many XML standards, including links to additional coverage for each.

Connecting to the cloud, Part 2: Realize the hybrid cloud model
This is Part 2 of a three-part series on connecting to the cloud. To determine the best solution for creating a hybrid cloud application, Part 1 examined some of the offerings from the major cloud platform vendors. In this article, Part 2 of the series, you will implement the hybrid cloud application, which combines local application components with cloud computing. The application makes use of a JMS queue locally as well as an SQS queue in the cloud, combining the two in a single hybrid application.

Ten XML Schemas you should know
In this article, look at some top XML schemas that provide solutions for all sorts of problems, from the basics of Web services to data description. You'll also cover database-like solutions that involve contacts and invoices. The schemas in this article were chosen for their usefulness and utility, plus their impact on the XML community in how information is shared and exchanged using the XML format.

Services-based enterprise integration patterns made easy, Part 3: Web services and registry
Part 1 and Part 2 of this series covered the basic concepts necessary to
develop services-based integration patterns. This article, the third in the series,
and the upcoming Part 4 further develop these ideas so the services-based
integration patterns become full-blown services-based patterns. This article in
particular deals with the components that are together commonly referred to as Web
services, which were originally designed for services that can be accessed over the
Internet. You'll also see that many of the Web services components can be used with
services that don't use the Internet and that only require a network connection.

Generate Web services for DB2 9 pureXML
Web services are important building blocks to achieve service-oriented architecture. As more and more applications move towards a Service Oriented Architecture, often times there is a need to expose application functionality as Web services. The purpose of this article is to show how you can easily generate Web services using a simple Java class to insert and retrieve XML data, into, and from DB2 9 using the pureXML feature. Once the Web services are generated and deployed on WebSphere Application Server, you can test it using either the built in Web services Explorer of Rational Application Developer (RAD) or XForms as a Web services client. The same services can be used by any Web services client that can make SOAP over HTTP Web service calls.

Hit the ground running with AIDE, Part 7: Better IT management
The IBM Autonomic Integrated Development Environment (AIDE) facilitates a model-driven approach to touchpoint development, which is a useful, factory-style, wizard-assisted pattern for producing generic touchpoints. However, at some point in the AIDE-driven workflow, the touchpoint must be made specific to a given application. You can do this either at the model design stage or manually through hard-coding. In this tutorial -- the seventh in the series -- discover techniques for creating both generic and specific touchpoints, and learn how to produce touchpoints that have the right mixture for a given management application.

That excitement over a new "toy" often influences architects and developers to attempt to solve everything with this single solution. However, applying a single solution approach throughout a distributed application can have significant impact on performance, resource utilization, and other quality attributes. Here's why you need to think before putting all your eggs in a single basket.

Contrary to what some might believe; however, these distinct Service-Oriented Architecture (SOA) design patterns are not mutually exclusive. Nor is one generally superior to the other. Each have their relative strengths and weaknesses in relation to different application scenarios, and both are valid approaches to solving real problems faced by real customers.

For instance, Microsoft's .NET Web services engine does not support Sw/A, so if you want to interoperate with .NET, you must use some other alternative. Learn a new way to modify an existing Web service that uses attachments to send binary data to another service that does not.

The Python Web services developer: The power of three: Python, Web services, and XSLT
This column has covered the major Python APIs for Web services processing, yet the enthusiasm for Web services development has been notably muted in the Python community compared to that of, say, the Java community. One way to augment the Python features for Web services processing is to take advantage of the most popular specialized language for XML processing: XSLT. Python offers several good tools for XSLT processing, and you can tap into this mine to enhance Web services processing capabilities. This article will show you how. You should be familiar with XSLT in order to follow the examples.

He looks at the real-world SOAP implementations from IBM and Microsoft and examines the limitations of XML -- SOAP's underlying encoding format -- and the problems involved in it as a full-fledged programming language. The article includes sample code for RPC and SOAP airline ticket requests, for side-by-side comparison.

A simple SOAP client
This article describes a simple, general purpose SOAP client in Java that uses no specialized SOAP libraries. Instead of creating the SOAP request XML document for you under the hood, this client lets you create your own request with any XML editor (or text editor). Instead of merely giving you the remote method's return values, the client shows you the actual SOAP response XML document. The short Java program shows exactly what SOAP is all about: opening up an HTTP connection, sending the appropriate XML to invoke a remote method, and then reading the XML response returned by the server.

Brett examines RPC, XML-RPC, RMI, and SOAP in detail, comparing and contrasting the use of each, and discusses whether SOAP makes sense. This article also includes sample code for a SOAP envelope.
