openejb-jar.xml define las características específicas de EJBs sobre Geronimo. Tiene tanto información de EJB como sus relaciones. Además proporciona una liga al pool de base de datos de la aplicación. Entity Beans en la aplicación dependen de esa pool. Nota que la parte final de este archivo define una Container Managed Relation (CMR) 1-N entre los Beans Customer y Account.

BankPool.xml es un archivo de configuración típico de una pool de base de datos, la cual se conectará a BankDB, definida en el servidor de base de datos incluído: Derby. Entity beans de la aplicación se refieren a la base de datos mediante su archivo de configuración.

geronimo-application.xml y application.xml definen los componentes principales del EAR. La información de archivos de los componentes EJB y Web se proporcionan en estos archivos. Además, estos dos archivos XML definen el uso del pool de base de datos en esta aplicación, indicándolo mediante tranql-connector-1.2.rar y BankPool.xml.
