A module that conforms to the Service Component Architecture (SCA) with well-defined interfaces. The module makes its function available to requesters by exporting its interface through an export. The module acts as a requester to a service provider by importing the provider's requirements through an import. It is possible to specify an export from another module as a target in an import. The modules are then packaged in a standard WebSphere Enterprise Archive (EAR) file. An EAR file contains all the files required to deploy the application.
