ErpConfigContext and ODataQueryBuilder throw error when trying to connect through Odata service

I am trying to build an app for Cloud solution. When trying to run the app locally, I got error:

java.lang.NoClassDefFoundError:

com/sap/cloud/sdk/odatav2/connectivity/ODataException.

This is running on Java EE 7 Web Profile Tomee 7 server.

As I can see in your code, you are querying a custom OData service of SAP S/4HANA. For OData queries to custom OData services, you might also consider using the Virtual Data Model (VDM) of the S/4HANA Cloud SDK instead of ODataQueryBuilder. To use the VDM with a custom OData service, one can use the VDM generator as described in the following blog post. By the way, it also works for the S/4HANA On-Premise. You can find more details on the customising here.
