/**
* Implementation of the ConfigurationService business methods of the
* administration interface.
*
* This class holds all business logic of the service related to administrative
* tasks like getting all configuration keys or single configuration values.
* On this level only primitve types String, int, long and boolean are used.
* The wellformed and complex typed interfaces for the specific services are
* using this more simple interface.
*
* Implementing the business interface ConfigurationServiceAdminInterface and
* thus the ConfigurationServiceCommonInterface.
*
* IMPORTANT:
* Because of XDoclet Bug in current version, we define deligators to the super
* class with ejb-tags here.
* These should be deleted if XDoclet is fixed.
