The nice thing about JavaOne is that if you can’t get into the session that you wanted, the fall-back option probably kicks butt anyway 🙂 Having missed out on the Grails/JFX/Android combo, I had the pleasure of getting the low down on Apache Tuscany, an open source Service Component Architecture(SCA) implementation. Tuscany is really about empowering the domain developer to produce and integrate local and remote services in the same way without caring about the underlying transport details.
Think dependency injection where the services that your class uses being accessible on some remote point in the cloud, and exposed using web services. As far as you are concerned, you use the interface, and let Tuscany take care of the rest. Likewise, if you want to expose your service classes to the cloud, you code up the business logic, and leave Tuscany to weave its magic. Great stuff!
