Explore the key concepts pertaining to Service Component Architecture (SCA) composites. SCA composites consist of components that implement business functions in the form of services. You can develop components that use Web services and Enterprise JavaBean (EJB) sessions and define bindings that enable the components to run on product servers. You typically do not deploy SCA composites directly onto a product server. To deploy SCA composites, you import SCA composites as assets to the product repository and then add the assets to business-level applications.
