The SCA Java Common Annotations and APIs specification defines Java APIs and annotations that enable service components and service clients to be built in the Java programming language. There are closely related models describing how other Java-based frameworks and models can be used in the context of SCA, such as Spring and EJBs, which also use the common annotations and APIs defined here. In addition, the Java Component Implementation specification defines a simple Java POJO model for creating service components.

This specification can be downloaded from the Open SOA Collaboration.
