Trying to create custom OData v2 service with data source from S/4HANA Cloud using S/4HANA Cloud SDK

Question

I am trying to create a custom OData v2 service in java with an S/4HANA Cloud data source using S/4HANA Cloud SDK. I tried to follow section 8.3 of the SAP Press book \"Extendi

Answer 1

The setup for OData V2 provisioning looks a bit different. So remove all modifications you did to use OData V4 provisioning. Then add the following:

1. Add the following dependencies (instead of the odata-v4 one) to your application/pom.xml file:

   
       com.sap.cloud.servicesdk.prov
       odata2.web
       
           
               javax.servlet
               servlet-api
           
       
   
   
       com.sap.cloud.servicesdk.prov
       odata2.xsa
   
   
       com.sap.cloud.servicesdk.prov
       odatav2-hybrid
       
           
               javax.servlet
               servlet-api
           
       
   
   
       com.sap.cloud.servicesdk.prov
       odatav2-prov
   
   

2. Add the following entries to your application/src/main/webapp/WEB-INF/web.xml file, replacing YOUR.PACKAGE with a package to search for your OData endpoints:

   
       ODataServlet
       org.apache.olingo.odata2.core.servlet.ODataServlet
       1
       
           org.apache.olingo.odata2.service.factory
           
               com.sap.cloud.sdk.service.prov.v2.rt.core.CloudSDKODataServiceFactory
           
       
       
           org.apache.olingo.odata2.path.split
           1
       
   
   
       ODataServlet
       /odata/v2/*
   
   
       package
       YOUR.PACKAGE
   
   
       
           com.sap.cloud.sdk.service.prov.v2.rt.core.web.ServletListener
       
   
   

3. Add an OData V2 edmx file to the application/src/main/resources/edmx directory.

These steps should get your OData V2 Provisioning service up and running.
