odata4j doesn't recognize WCF-$metadata correctly #226

Closed GoogleCodeExporter closed 8 years ago

GoogleCodeExporter commented 8 years ago
What steps will reproduce the problem?
1. I created a new project (Empty ASP.NET Web Application) with Visual studio 
2012 und WCF Data Services Tools 5.1
2. I added an ADO.NET Entity Data Model and imported the AdventureWorks 
Database to the model.
3. I added a WCF Data Service 5.1 and exposed the Employee-Table
4. I tried to fetch the Employee-Table with odata4j-client, but it seems like 
the Metadata is not parsed correctly

        reportMetadata(c.getMetadata());
        for(OEntity employee : c.getEntities("Employee").execute()){
            reportEntity("test", employee);
        }

What is the expected output? What do you see instead?
An output of the Metadata, as well as the Employee-Entities.

But there is no output for the metadata at all.

Furthermore, there is an Exception thrown for the getEntities():

sRequest.java:64)

What version of the product are you using? On what operating system?
odata4j-0.7.0-clientbundle.jar
Visual Studio 2012, WCF Data Services 5.1

Please provide any additional information below.

The $metadata is :

WCF DS 5.1 by default uses OData V3.

Try setting it to OData V2:

public static void InitializeService(DataServiceConfiguration config)
{
  config.DataServiceBehavior.MaxProtocolVersion = DataServiceProtocolVersion.V2;
  ...
}

Able to repro, http://schemas.microsoft.com/ado/2009/11/edm is the problem.  
I'll take a look.
