Last week I presented a session at AJAXWorld 2008 in San Jose, titled “Hands On Data Services for RIA, WOA, and SOA”.  While the “hands on” part was a demonstration of the XAware technology, where I showed building a data mashup from text data logically linked to a database, the first half of the presentation was a discussion abo

I attended AJAXWorld 2008 in San Jose last week, where I sat in many sessions and also presented a session myself.  It was a good and interesting show, focused mainly on Rich Internet Application (RIA) development technologies.  While my day job usually has me dealing with back-end server, data integration, and data services issues, it

A key design principle for a Service Oriented Architecture (SOA) is the definition of a service contract.  The contract clearly specifies the technical interface a client uses to invoke each service operation, as well as the expected behavior of the service.  The contract is independent of the underlying implementation, so users of the

In a recent SDTimes column, David Linthicum discussed "mashups" and whether they are consistent with SOA principles. David identifies two broad categories of mashups: visual mashups like Google maps displaying locations from a sex offender database, and non-visual mashups combining two or more other servic

In previous blogs, I have discussed contract-first service design and the benefits to constructing services as information-rich, smart endpoints. In his most recent book, SOA: Principles of Service Design, Thomas Erl formalizes and extends the

XAware uses Spring Security (formerly called the Acegi project) to control access to XAware-based services invoked over HTTP.

 

XAware's security model includes authentication and access control. A user is authenticated with a user name and password, and is allow

The "Long Tail " moniker has been used (some would say overused) in marketing and mass media over the last couple years. Now, as different use cases for SOA evolve, the metaphor seems appropriate to explain the growing use of services outside of the core domains of SOA, business process implementation and integration. If y

Mark Scrimshire blogged about attending a Ray Valdes presentation on Portals and Mashups (http://ekive.blogspot.com/2008/03/portals-and-mashups-putting-powr-of-soa.html).  The article nicely explains how Web 2.0 and SOA technologies combine to produce a new generation of portals, fed by information culled from throughout the enterprise.  The separation of concerns between Web 2.0 an

I attended EclipseCon 2008 this week in Santa Clara, CA.  Wednesday's keynote speaker was Sam Ramji from Microsoft, talking about Microsoft's growing participation in Open Source initiatives. He began by confirming rumors that a new initiative, "Supernova", would have Microsoft purchasing the Eclipse organization, and acquiring all intellectual property of Eclipse. A couple

Service development is about to explode in the enterprise, but these are not the custom-crafted, high value, reusable services you might see cruising the pristine avenue of your company’s SOA center of excellence. No, this will be massive. Instead of nicely architected brownstones with clean lines and aesthetic appeal, you’ll brush with small, hastily constructed, one-off services as
