# Class PropertiesRoleMappingListener

java.lang.Object
org.apache.catalina.core.PropertiesRoleMappingListener

All Implemented Interfaces:
  `LifecycleListener`

public class PropertiesRoleMappingListener extends Object implements LifecycleListener
Implementation of `LifecycleListener` that will populate the context's role mapping from a properties file.

This listener must only be nested within `Context` elements.

The keys represent application roles (e.g., admin, user, uservisor, etc.) while the values represent technical roles (e.g., DNs, SIDs, UUIDs, etc.). A key can also be prefixed if, e.g., the properties file contains generic application configuration as well: `app-roles.`.

Note: The default value for the `roleMappingFile` is `webapp:/WEB-INF/role-mapping.properties`.
