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

Question

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.

Can you add the output of `mvn dependency:tree` to your question? It seems like the `com.sap.cloud.servicesdk:odatav2-connectivity` library is missing on your classpath/in your `pom.xml`. — Christoph Schubert, Apr 24 '19 at 06:27

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.

I followed the blog and generate VDM. But now I got the compilation error for the generated java at the line import com.sap.cloud.sdk.s4hana.datamodel.odata.helper.OneToOneLink; WorkOrderOneToOneLink.java:[12,55] cannot find symbol [ERROR] symbol: class OneToOneLink. I checked the POM and it looks ok. Any suggestion on this? Thanks. – Tracy Apr 24 '19 at 13:05
Do you have the `com.sap.cloud.s4hana.datamodel:odata-core` dependency on your classpath? The deep dive blog posts assumes, that you use one of our archetypes to consumer your generated VDM. – Christoph Schubert Apr 24 '19 at 13:11

Thanks, Christoph. I fixed it by changing the SAP Cloud SDK version in POM to 2.14.0, which is the latest one so far. com.sap.cloud.s4hana sdk-bom 2.14.0 – Tracy Apr 24 '19 at 13:37
