> If I set {{ODataJPAContext.setDefaultNaming(false)}} then simple request stop working: http://localhost:8080/olingo.odata2.sample.cars.web/MyODataJPA.svc/Productss
> with this error:
> {quote}
> java.lang.ClassCastException
> org.apache.olingo.odata2.core.edm.provider.EdmSimplePropertyImplProv cannot be cast to org.apache.olingo.odata2.api.edm.EdmNavigationProperty
> org.apache.olingo.odata2.core.ep.aggregator.EntityInfoAggregator	createNavigationInfoObjects	383

> *The problem in ManyToOne fields.*
> I debug a little and realized that method {{org.apache.olingo.odata2.core.ep.aggregator.EntityInfoAggregator.createNavigationInfoObjects}} receiving {{propertyNames}} list with propery names that already in {{edmProperties}} as {{EdmSimplePropertyImplProv}}. But if I set {{ODataJPAContext.setDefaultNaming(true)}} then the same method receiving list with navigation propery names as *JpaEntityClassNameDetails* so the names are different and all working fine.
> I dont know how to fix this but because of this behavior we can't just use  {{ODataJPAContext.setDefaultNaming(false)}} for ManyToOne fields.
> I attach a simple maven project with my Entities and simple servlet for run in tocmat. Problematic entity is {{Products}}.
