All service components such as business rules, mediator, BPEL processes, adaptors, and others are packaged in a single .sar file called Service Archive.

The deployment descriptor for a .war file is web.xml; similarly, the composite application assembly model uses composite.xml. The composite.xml file conforms to the SCA specifications. The composite...
