Composites
A composite is a configuration of services comprising an application that conforms to a service-oriented architecture. A composite contains components, services, references, the wires that interconnect them, and properties that are used to configure the components. Composites can be nested (contained by other composites). A root composite equates to an SCA application.
See the SCA Assembly specification for information on service-oriented architectures.
The constituents of a Composite can run in a single process on a single computer or be distributed across multiple processes on multiple computers. A complete Application might be constructed from just one Composite or it could combine several different Composites. The Components making up each Composite can be implemented using different technologies.
