Why and when to perform this task
A resource reference supports application provider access to a resource (such as a data source, URL, or mail provider) using a logical name rather than the actual name in the run time environment. This ability insulates the application provider from the run time configuration, and simplifies the process of changing the run time configuration.Resource references are declared in the deployment descriptor by the application provider. At some point in the application deployment process, you must bind the resource reference to the actual name of the resource in the run time environment.
