Chandan V.A commented on OLINGO-312:
------------------------------------
Hi,
The Interface JPAEdmExtension is extended with the method
getJPAEdmMappingModelStream. Implement this method to return a Stream of
Mapping model. This should solve your issue.
Please reopen the ticket in case this solution does not solve your use case.
Thanks
Kind Regards

> Reading resource via Classloader

> Key: OLINGO-312
> URL: https://issues.apache.org/jira/browse/OLINGO-312
> Project: Olingo
> Issue Type: Bug
> Components: odata2-jpa
> Affects Versions: V2 1.2.0
> Reporter: Giacomo Pati
> Assignee: Chandan V.A
> Fix For: V2 1.3.0
>
>
> While many servlet-containers tested by me work fine with construct below,
> WebSphere 8 doesn't like it and returns null for the resources path requested
> (it's actually outside of Classloader managed filesystem area, which I would
> consider being bad practice):
> {code}
> InputStream is =
> JPAEdmMappingModelService.class.getClassLoader().getResourceAsStream("../../"
> + mappingModelName);
> {code}
> As the class in question (JPAEdmMappingModelService) doesn't have access to
> the servlet context to properly read a file from the web space area I'd
> suggest (also for backwards compatibility reasons) to add this to the code as
> shown in the following patch:
> {code}
> @@ -195,6 +195,9 @@ public class JPAEdmMappingModelService implements
> JPAEdmMappingModelAccess {
> protected InputStream loadMappingModelInputStream() {
> InputStream is =
> JPAEdmMappingModelService.class.getClassLoader().getResourceAsStream("../../"
> + mappingModelName);
> + if(is == null) {
> + is =
> JPAEdmMappingModelService.class.getClassLoader().getResourceAsStream(mappingModelName);

> which would alternatively allow to put the mapping file into the
> WEB-INF/classes folder.
