Last month in Part I (WSJ Vol. 2 Issue 1) we discussed J2ME and accessing Web services from wireless devices using the XML-RPC protocol. In this article, we will consider SOAP as a vehicle for accessing Web services from wireless devices, comparing and contrast-ing it with XML-RPC. Our sample application will again be a J2ME midlet, however, we will use EnhydraME's kSOAP rather than kXML-RPC to provide the protocol's implementation. Overview of SOAP The Simple Object Access Protocol is, according to the 1.1 specification, "a lightweight protocol for exchange of information in a decentralized, distributed environment." The protocol is entirely based on XML, vendor-neutral, and one of the cornerstone technologies in the Web services revolution. It is quite similar to XML-RPC, but we will examine that more closely in the next section. SOAP was originally conceived and ... (more)

Juggling Multiple Data Models with Services

Recently, a client approached me with a quandary.  When designing XML schemas for Web services, how do you balance the desire to use industry standards such as UBL ( Universal Business Language) or CICA ( Context Inspired Component Architecture) to support data interoperability with the unique needs of particular domains and sub-systems within the enterprise?  The client’s service design team is rightfully concerned with the competing interests of internal enterprise standardization, interoperability with external entities, and addressing the unique needs of local domains and p...

Is there a method to your madness?

“Art and science have their meeting point in method.” – Robert Bulwer-Lytton (19th Century English statesman and poet) Much of what architects must do centers around that delicate balance between artist elegance and exacting science.  Some describe this as an architecture process while others are more comfortable with the term method or methodology.  Whatever term you use, the method/process employed by an architect is the central thread that ties together techniques, the creation of artifacts, the utilization of reference models, and the application of patterns and templates (a...

The Hype About .NET

You've heard the hype about .NET. You've read a couple of vague articles about dynamic discovery and invocation, service-oriented architecture, and how SOAP and a handful of other XML standards are forever changing the software industry. These ideas have intrigued you and you're interested in learning more - or at the very least, you recognize the importance of being able to add these acronyms to your resumé. In either case, you want to explore the world of .NET, but are unable or unwilling to fork over a thousand bucks for Microsoft's Visual Studio .NET product. This article is ... (more)

Ten Steps to Successful Cloud Adoption

A Journey of False Starts This is not the first time you’ve had your heart set on revolutionizing your information systems: One year, you rolled out a big Enterprise Application Integration (EAI) initiative, but it was too brittle and carried high maintenance costs. For a while you experimented with Web Services, but found that while they were easy to work with, they were largely insufficient to meet your broader needs due to a lack of architectural design guidelines. Out-sourcing, in-sourcing, up-sourcing, down-sourcing, and cross-sourcing just seemed to shuffle the work aroun... (more)
