Note: The application-descriptor file has no contents and no name; it only has the file extension “xsapp”,
for example, .xsapp. For backward compatibility, content is allowed in the .xsapp file but ignored.
The application descriptor file performs the following operations:
● Determines the called application
The application root is determined by the package containing the .xsapp file. If the package sap.test
contains the file .xsapp, the application will be available under the URL http://:/
sap.test/.
4.4.2 Create an Application Descriptor File
Each application that you want to develop and deploy on SAP HANA Extended Application Services (SAP HANA
XS) must have an application-descriptor file. The application descriptor is the core file that you use to describe an
application's framework within SAP HANA XS.
The package that contains the application-descriptor file becomes the root path of the resources exposed by the
application you develop.
1. Create a root package for your application, for example, helloxsjs.
2. Create an application descriptor for your application and place it in the root package you created in the
previous step.
The application descriptor is the core file that you use to describe an application's availability within SAP
HANA Extended Application Services. The application-descriptor file has no contents and no name; it only has
the file extension .xsapp..
Note: For backward compatibility, content is allowed in the .xsapp file but ignored.
3. Save and activate your changes and additions.
4.4.3 The Application-Access File
SAP HANA XS enables you to define access to each individual application package that you want to develop and
deploy.
The application-access file enables you to specify who or what is authorized to access the content exposed by a
SAP HANA XS application package and what content they are allowed to see. For example, you use the
application-access file to specify if authentication is to be used to check access to package content and whether if
rules are in place for the exposure of target and source URLs.
The application-access file does not have a name; it only has the file extension .xsaccess. The content of
the .xsaccess file is formatted according to JSON rules and is associated with the package it belongs to as well
as any subpackages lower in the package hierarchy. Multiple .xsaccess files are allowed, but only at different
levels in the package hierarchy. This enables you to specify different application-access rules for individual
packages and subpackages in the package hierarchy.
Note: You cannot place two .xsaccess files in the same package. Furthermore, the rules specified in
a .xsaccess file that is associated with a subpackage take precedence over any rules specified in
a .xsaccess file associated with any parent package higher up the package hierarchy.
The application-access file performs the following operations:
● Data exposure

Use the exposed keyword to specify if package content is to be exposed to client requests via HTTP.
