This page describes the OpenEJB-specific configurations required to deploy EJB onto Geronimo.
The CMP engine gains access to the database used to store the entity beans via the connection factory identified by the <cmp-connection-factory> element. This latter is a "generic" element providing enough information to identify a JDBC data source already deployed or being deployed along with the CMP entity beans.
The configuration of such a relationship requires the mapping of one and only one CMR field of the two related entity beans. The identification of the mapped CMR field is achieved via the relationship-role-source and cmr-field elements. The mapping per se is provided via the role-mapping element. This latter is a collection of cmr-field-mapping elements specifying the mapping between the columns of the two tables associated to the related entity beans.
