JmDNS : Easy Service Discovery for the 21st Century

Service-oriented architectures (SOAs) are all the rage. But how do you find all of these services once they are deployed? Configuration files are so 90's. Software of the 21st Century should be able to find related services and components without users having to specify particular configurations at start up. The IETF's ZeroConf multicast DNS protocol was designed to solve exactly this problem. JmDNS is Java-based open source implementation of this capability that allows local-link applications to find and use automagically discovered capabilities. Apple's Rendezvous technology is another open-source ZeroConf implementation behind many of the exciting applications it is building for OS X these days. Come learn how you can interact with these or your own service discovery-savvy applications without even having to learn how to spell UDDI. Bring your wireless notebooks to participate in a service-oriented environment (please have a working Java environment as we won't have time to debug installation issues).

Attendees will learn

  • Why you don't need UDDI to find services
  • The basics of multicast DNS and the ZeroConf protocol
  • How to take advantage of Bonjour-enabled devices and software
  • How to build their own applications that can be found without a central repository
