Sample CMP bean deployment on WL 7.0

[anshulgoswami]

Hi, I am trying to deploy ejb20_basic_containerManaged.jar provided in the weblogic 7.0 samples. I have created the connection pool and the data source but at the time of ejb deployment I am getting the following error:

Unable to deploy EJB: containerManaged from ejb20_basic_containerManaged.jar:

weblogic.ejb20.WLDeploymentException: The DataSource with the JNDI name: examples-dataSource-demoPool could not be located. Please
ensure that the DataSource has been deployed successfully and that the JNDI name in your EJB Deployment descriptor is correct.
