EIS Mappings (ELUG)
Creating and Configuring EIS Mappings
EclipseLink enterprise information system (EIS) mappings provide support for accessing legacy data sources and enterprise applications through Java EE Connector architecture (JCA) adapter. EclipseLink EIS mappings use the JCA Common Client Interface (CCI) to access the EIS through its resource adapter. This provides the ability to directly map from an existing Java object model to any transactional data source, such as mainframes with flat file/hierarchical data. An EIS mapping transforms object data members to the EIS record format defined by the object's descriptor.
