javax.el.ELException: oracle.adfinternal.controller.savepoint.SavePointException: ADFC-08011: Oracle ADF

Sometimes we get the following error when working with oracle ADF

javax.el.ELException: oracle.adfinternal.controller.savepoint.SavePointException: ADFC-08011: The JNDI connection name is not specified in configuration file adf-config.xml.

This is because the data source is not configured in the adf-config.xml which tells the framework the place the store the current snapshot of the application

it can be done as shown in my previous blog step1
