Defining data sources for entity beans
An application that is installed on an application server must have bindings defined before you can start the application. The Enterprise JavaBeans (EJB) references and resource references that are defined in the application must be bound to the actual enterprise beans or resources that are defined in the application server.
Before you begin
About this task
For more information, see the topic Application bindings.
Before you do this task, it is assumed that the entity beans in your application are container-managed persistence (CMP) enterprise beans.
If you bind an EJB module to a data source, all beans in that module use the same data source for persistence. If you specify the data source at the bean level, then that data source is used instead.
See the assembly tool documentation for the steps on how to complete this task.
