Subject [jira] [Commented] (OLINGO-1062) Cannot consume Odata Reference Services with Annotations
Date Wed, 14 Jun 2017 08:57:00 GMT

    [ https://issues.apache.org/jira/browse/OLINGO-1062?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16048889#comment-16048889

Lars Laegner commented on OLINGO-1062:
--------------------------------------

Hi Ramya,

Thanks for the code example!
annotation.getTerm() works, but the issue is, that edm.getTerm() fails, which uses the annotation.getTerm()
internally. 
So it is still an issue from the surrounding olingo edm method. 
This fails to deliver a value.

Ciao
Lars

>             Project: Olingo
>          Issue Type: Bug
>          Components: odata4-client
>    Affects Versions: (Java) V4 4.3.0
>            Reporter: Lars Laegner
>
> The http://services.odata.org/TripPinRESTierService/ service returns the following annotation:
> ...
> <EntitySet Name="Airlines" EntityType="Microsoft.OData.Service.Sample.TrippinInMemory.Models.Airline">
<Annotation Term="Org.OData.Core.V1.OptimisticConcurrency"> <Collection> <PropertyPath>Name</PropertyPath>
</Collection> </Annotation> </EntitySet> ...
> unfortunately, the used Org.OData.Core.V1 namespace is not referencing anywhere an alias
or namespace in the schema.
> This results, when retrieving the code with the latest available OData V4 Lib for Java,
in the EdmAnnotationClass Code
> public EdmTerm getTerm() { 
> if (term == null) { 
> if (annotation.getTerm() == null) { throw new EdmException("Term must not be null for
an annotation."); } 
> term = edm.getTerm(new FullQualifiedName(annotation.getTerm())); 
> } 
> return term; }
> that in debugging the annotation.getTerm()=="Org.OData.Core.V1.OptimisticConcurrency"
but the term is then set to null from edm.getTerm() as it seems to check for available namespace/aliases
in the schema and cannot find one.
> So practically, this annotation does not exist for the currently latest Olingo-OData-Client-for-Java-4.3.0
> The same for http://services.odata.org/V4/(S(tauqx0n1pg4nytucatnssdwb))/TripPinServiceRW/
> I have cross created this issue in https://github.com/OData/odataorg.github.io/issues/117
as i am not sure, wether the service is not correct or the client should be more forgiving
