ABSTRACT:
A container managed persistent (CMP) enterprise java bean (EJB) framework includes support for accessing multiple data sources within one deployment. A CMP EJB includes a number of different attributes that can be a variety of values. A session EJB that acts as a front-end to the CMP EJP includes a resource reference for each of the different data sources that the entity CMP EJB may utilize. The application server environment includes a map that defines mapping information between the attributes of the CMP EJB and the resource references of the session EJB. Using the mapping information during runtime, the application server connects to the appropriate data source.
