The configuration directory can contain resources that complement and override configuration, user interface, and business logic after the application is deployed. Overriding is provided by the loading mechanism of the Resources infrastructure interface. Firstly it performs the search in the configuration directory and then in the classpath, so that resources from the configuration directory take precedence over identically named resources located in JAR files and class directories.

The configuration directory may contain resources of the following types:

The location of the configuration directory is determined by the cuba.confDir application property. In case of fast deployment in Tomcat, it is a subdirectory with the web application name in the tomcat/conf directory, for example, tomcat/conf/app-core for the Middleware. For other deployment scenarios, the configuration directory is located inside the application home.
