ECF is a set of frameworks for building distributed servers, applications, and tools. It provides a modular implementation of the OSGi 5 Remote Services standard, along with support for REST-based and other types of remote services.
See the ECF Wiki for examples, tutorials, other documentation, as well as plans and efforts currently underway for future releases.
