If I am getting this error, initialy I will check whether the settings are done approriately. Here is the user manual for JDBC Data Source
1. [JDBC Data Sources - Virtual DataPort Administrator Guide](https://community.denodo.com/docs/html/browse/8.0/en/vdp/administration/creating_data_sources_and_base_views/jdbc_sources/jdbc_sources)
For connecting to the ds_web_orders data source, I would use the below Database URL
**Note**: You can either user data-server as your hostname or IP address of the Virtual Machine. You can refer to the Denodo Training QuickStart Virtual Machine - User Manual which is available in the downloaded folder of the VM for more details.
Hope this helps!
