Summary: Unable to retrieve a referenced metadata document
referenced by Microsoft dynamics metadata document
Key: OLINGO-1060
URL: https://issues.apache.org/jira/browse/OLINGO-1060
Project: Olingo
Issue Type: Bug
Components: odata4-client
Affects Versions: (Java) V4 4.3.0
Reporter: Sumit
Below is a sample metadata document as given by a microsoft dynamics instance
<?xml version="1.0" encoding="utf-8"?>
<edmx:Edmx Version="4.0" xmlns:edmx="http://docs.oasis-open.org/odata/ns/edmx";>
<edmx:Reference
Uri="http://vocabularies.odata.org/OData.Community.Keys.V1.xml";>
<edmx:Include Namespace="OData.Community.Keys.V1" Alias="Keys" />

The referenced metadata document
http://vocabularies.odata.org/OData.Community.Keys.V1.xml has 'Content-Type'
header set to "text/xml" in response. But olingo's
AbstractMetadataRequestImpl[0] sets 'Accept' header to "application/xml" in the
request for fetching the metadata document. As a result we get 406 response
code (since the accept header does not contain the type as specified in the
respone.
Should "text/html" be added to Accept header of metadata request ?
