The SCA Java Client and Implementation model for Spring specifies how the Spring Framework can be used with SCA. The goals of this effort are:
Coarse-grained integration: The integration with Spring will be at the SCA Composite level, where a Spring application context provides a complete composite, exposing services and using references via SCA. This means that a Spring application context defines the internal structure of a composite implementation.
Start from SCA Component Type: It should be possible to use Spring to implement any SCA Composite that uses WSDL or Java interfaces to define services, possibly with some SCA specific extensions.
Start from Spring context: It should be possible to use any valid Spring application context as the implementation of a component within SCA. In particular, it should be possible to generate an SCA Composite from any Spring context and use that composite within an SCA assembly.
