Unsupported Media Type

Hi all,

I've created a OData service formulated by the following metadata:

<edmx:Edmx Version="1.0" xmlns:edmx="http://schemas.microsoft.com/ado/2007/06/edmx">

  <edmx:DataServices m:DataServiceVersion="2.0" xmlns:m="http://schemas.microsoft.com/ado/2007/08/dataservices/metadata">

  <Schema Namespace="HanaODataTests.bookstore" xmlns="http://schemas.microsoft.com/ado/2008/09/edm" xmlns:d="http://schemas.microsoft.com/ado/2007/08/dataservices" xmlns:m="http://schemas.microsoft.com/ado/2007/08/dataservices/metadata">

  <EntityType Name="booksType">

  <Key>

  <PropertyRef Name="title"/>

  </Key>

  <Property MaxLength="100" Name="title" Nullable="false" Type="Edm.String"/>

  <Property MaxLength="100" Name="ISBN" Type="Edm.String"/>

  <Property Name="editions" Type="Edm.Int32"/>

  <Property MaxLength="100" Name="author.name" Type="Edm.String"/>

  <Property Name="author.birth" Type="Edm.DateTime"/>

  <NavigationProperty FromRole="booksDependent" Name="Author" Relationship="HanaODataTests.bookstore.WroteType" ToRole="writersPrincipal"/>

  </EntityType>

  <EntityType Name="writersType">

  <Key>

  <PropertyRef Name="name"/>

  <PropertyRef Name="birth"/>

  </Key>

  <Property MaxLength="100" Name="name" Nullable="false" Type="Edm.String"/>

  <Property Name="birth" Nullable="false" Type="Edm.DateTime"/>

  <Property MaxLength="100" Name="title.title" Type="Edm.String"/>

  <NavigationProperty FromRole="writersPrincipal" Name="Titles" Relationship="HanaODataTests.bookstore.WroteType" ToRole="booksDependent"/>

  </EntityType>

  <Association Name="WroteType">

  <End Multiplicity="1" Role="writersPrincipal" Type="HanaODataTests.bookstore.writersType"/>

  <End Multiplicity="*" Role="booksDependent" Type="HanaODataTests.bookstore.booksType"/>

  <ReferentialConstraint>

  <Principal Role="writersPrincipal">

  <PropertyRef Name="name"/>

  </Principal>

  <Dependent Role="booksDependent">

  <PropertyRef Name="title"/>

  </Dependent>

  </ReferentialConstraint>

  </Association>

  <EntityContainer Name="bookstore" m:IsDefaultEntityContainer="true">

  <EntitySet EntityType="HanaODataTests.bookstore.booksType" Name="books"/>

  <EntitySet EntityType="HanaODataTests.bookstore.writersType" Name="writers"/>

  <AssociationSet Association="HanaODataTests.bookstore.WroteType" Name="Wrote">

  <End EntitySet="writers" Role="writersPrincipal"/>

  <End EntitySet="books" Role="booksDependent"/>

  </AssociationSet>

  </EntityContainer>

  </Schema>

  </edmx:DataServices>

</edmx:Edmx>

and to insert books and writers through a POST request is working but now I'm trying create a link between two entities. For that, I wrote the following request:

POST /HanaODataTests/bookstore.xsodata/writers(name='Test',birth=datetime'2014-07-11T00:00:00.0000000')/$links/Titles HTTP/1.1

Host: xxxxxxxxxx

DataServiceVersion: 1.0

MaxDataServiceVersion: 2.0

Content-Type: application/xml

 

<uri xmlns="http://schemas.microsoft.com/ado/2007/08/dataservices">

 

http://xxxxxxx/HanaODataTests/bookstore.xsodata/books('HAPI%20Hana%20Integration%20Test%20Volume%201')

 

</uri>

and I always get as a response:

<?xml version="1.0" encoding="utf-8" standalone="yes"?><error xmlns="http://schemas.microsoft.com/ado/2007/08/dataservices/metadata"><code/><message xml:lang="en-US">Unsupported character set: The entity of the request is in a format not supported by the requested resource for the requested method.</message></error>

Or sometimes the response is that the statement cannot be a POST statement because Titles are not an entity.

Anyone have any idea what I'm doing wrong?

Thank you for your attention

Pablo
