Mobile Connectors is a fantastic technology that enable you to write your business server, and then get proxy connection files automatically for iOS (Objective C), Android (Java), Blackberry (Java), Windows Mobile 7 (C#) without having to write another line of code!
The proxy files take the pain of having to write all the connections for REST servers away giving you a full set of files that implement seamlessly into your business applications, no matter what language your writing in.
Mobile Connectors are part of DataSnap, the fastest way to producing very scalable business middle tier servers using Delphi and C++ Builder.
