SOA & Web Services: Why Can't We Just Talk?

Wed, 16 May 2007 15:30:00 EDT

You may be wondering, why hasn't the uptake of Web services matched the bold predictions made when it was first launched? There are certainly more developers thinking about Web services with the advent of service-oriented architectures (SOA). However, the number of successful public Web services projects seems to be limited to a few high-profile companies like eBay and Amazon that have published APIs and end points, or developers who have been able to implement services internally but with a narrow and well-defined set of services - still a long way from the smart application that could self-select services at runtime.

SOA - Enterprise Mashup Services

Mon, 26 Mar 2007 15:15:00 EDT

Since Web 2.0 kicked off scarcely a day goes by without a headline targeting mashups and their enablers, AJAX and Web Services, as the next hot Web technologies. Mashups are Web sites that integrate a variety of services (e.g., news feeds, weather reports, maps, and traffic conditions) in new and interesting ways. Just take a look at Zillow.com, which provides instant home valuations plotted as thumbtacks on a map (Figure 1), or HousingMaps.com, which marks listings from craigslist.org as captions on a map, and you'll get a clear picture of the power behind converging data sources.

Enterprise Mashup Services

Sat, 17 Mar 2007 13:30:00 EDT

In my previous article, 'Enterprise Mashup Services: Real-World SOA or Web 2.0 Novelties?' (JDJ Vol. 11, Issue 12), I discussed how a Java-to-AJAX library such as Direct Web Remoting (DWR) can bridge the gap between mashup services implemented with JavaScript and business services written in Java, allowing developers to blend corporate services with external services such as Google Maps. The problem with this approach is that it relies on AJAX as an integration point, which entails a fragile development platform as well as the need to maintain browser-specific code due to idiosyncrasies in browser support for JavaScript - the primary technology behind AJAX. In addition, JavaScript lacks a standardized approach for componentizing code, making applications written in it difficult to consolidate and reuse. The solution to these shortcomings is to pair AJAX with a component framework. JavaServer Faces (JSF) provides this foundation and eliminates the complexities of JavaScript - besides providing rich integration with the Java EE platform.

Using Self-Signed Certificates for Web Service Security

Fri, 26 May 2006 15:15:00 EDT

One of the great things about the Java programming language is the Open Source community that provides great applications at little or no cost. An example of this is Apache Tomcat, which provides a solid Web server for development using servlet or JSP technology. Now that Web Service technology is maturing there's a potential for a whole scenario of applications to take advantage of a Swing feature-rich thin client on the front-end coupled to the data verification and business logic already developed in the Web or ejb tier. Such applications are only viable if they can be secure, however, security doesn't have to come at a great cost. The purpose of this article is to demonstrate how Web Service clients can use self-signed security certificates over the secure HTTPS protocol.

How to Develop with an Emerging Standard, Today

Sat, 01 Jan 2000 00:00:00 EST

Web services are the 'new kids on the block' and as with all adolescent technologies they are can be a little troublesome, take time to understand and always testing you with something new. Given this, how does a developer get started with Web services? And for those more experienced, how does the developer speed up the developing, debugging, and deployment cycle?
