Example 21 with DataAccessResourceFailureException

use of org.springframework.dao.DataAccessResourceFailureException in project opennms by OpenNMS.

     * logging an error, this is the only way this method indicates a problem with just one graph
     * The only cause for a real exception is if there's neither a "reports" nor a "report.id"
