Deployment Descriptors

A deployment descriptor is an XML file that captures changes to the deployment unit during deployment. Those changes are then used when a package is redeployed.

A deployment descriptor is not required to deploy the deployment unit.

A deployment descriptor is created either after a developer creates a package profile and executes a build on a package, or when the developer deploys a package to a development edition server from SAP Mobile WorkSpace. The file contains this information:

The deployment mode
The target package that descriptor applies to
The endpoint information that overrides specific endpoints defined for MBOs or operations in the deployment unit
The domain and named security that the package applied to
Role mappings

This information is specific to each deployment unit; therefore, you cannot apply a descriptor from another package to a deployment unit.
