  The goal for a SOA is a world wide mesh of collaborating services, which are published and available for invocation on the Service Bus. Adopting SOA is essential to deliver the business agility and IT flexibility promised by Web Services. These benefits are delivered not by just viewing service architecture from a technology perspective and the adoption of Web Service protocols, but require the creation of a Service Oriented Environment that is based on the following key principals: Service is the important concept. Web Services are the set of protocols by which Services can be published, discovered and used in a technology neutral, standard form. SOA is not just an architecture of services seen from a technology perspective, but the policies, practices, and frameworks by which we ensure the right services are provided and consumed. With SOA it is critical to implement processes that ensure that there are at least two different and separate processes—for provider and ...

Posted November 30th, 2007 by ronan http://dev.mobi/node/704 It has always surprised me that the mobile industry has not made better use of SVG. On the face of it, SVG is perfectly suited to publishing rich content on mobile devices for a number of reasons: It is a compact way of representing vector graphics SVG graphics (in keeping with the name) can be scaled to arbitrary sizes, removing some of issues with screen dimension proliferation on mobile devices It is an open standard Device support is better than you might think (more on this later) Because SVG is based on XML, many existing XML tools can be used to generate content This article summarises the capabilities of SVG and how best to take advantage of it for mobile applications. I will not attempt to describe how to build SVG content since there are plenty of good tutorials elsewhere (see References & Links section below). Description of SVG First a quick recap on what exactly SVG is all about. From the Wik...

Another way to do that is to use the DOM Level 2 API ( removeChild , createElement , appendChild ) but using innerHTML is by far the easiest and most efficient way to modify the DOM tree. However, innerHTML has few problems of its own that you need to be aware of: Improper handling of the innerHTML property can enable script-injection attacks on Internet Explorer when the HTML string contains a script tag marked as deffered: <script defer>...<script> Setting innerHTML will destroy existing HTML elements that have event handlers attached to them, potentially creating a memory leak on some browsers. There are a few other minor drawbacks worth mentioning: You don't get back a reference to the element(s) you just created, forcing you to add code to retrieve t...
