Re: [service-orientated-architecture] ZapThink needs help: Sample contracts?

[Ron Schmelzer]

To be specific, We're looking for help creating metadata, declarative contracts vs. application-specific contracts (CORBA has plenty of those). Anyone with guidance on how to create an uber Service contract? Jini is an interesting model, but I'm not sure how to translate that to Service contracts in an SOA specifically. Don't want to get into (another) debate about Jini here, but I want to focus the answers a bit more specifically on the problem at hand.

The RIO project at http://rio.jini.org, was initiated out of a request by the military for such stringent requirements out of a dynamic environment.  It provides QOS based deployment, migration of services and management services.  It utilizes XML to configure the system to specify a cybernode's capabilities to accept a particular service and other things. If you are not familar with this project, it's been around for many years, and has been utilized in many different types of applications. One of the hardest things to learn about Jini, is, who is using it.  If you've learned to use Jini, you've probably discovered how simple the concepts and software are to use and deploy.  This simple knowledge and small effort has a huge ROI.  Many people don't talk about using Jini because they consider it a competative advantage and do not want their competitors to know how they are out performming everyone.  Some have revealed their use of Jini, and you can find references to their experiences on the web. http://ajitsagar.javadevelopersjournal.com/jini_and_soa.htm has some interesting threads of thought that might shed some light on some of the places where Jini can be found.  Of course, you can also just search for "Jini SOA" on google and get a large number of returns to look at.
