Service Interface Deployment Package

Describes the files generated by Enterprise Developer when you deploy a service interface.
A service interface deployment package is generated when you deploy, and is contained in a COBOL Archive (.car) file. This is a standard zip archive that includes the following:
manifest file
An XML document that contains deployment information such as the name of the service and a description of the .car file.
interface definition table
A file that describes the service interface. The file extension is .idt.
specified package files
Other files optionally added to the package.

The name of a deployment package file is myService.car where myService is the name of your service interface. By default, Enterprise Developer generates the .car file in your project's myService.deploy directory.
