Microsoft Azure - Service Management Rest API - 400 Error

Hi,

I am trying invoke the Service management API https://management.core.windows.net/<subscription-id> and https://management.core.windows.net/<subscription-id>/services/hostedservices from Java. I have tried with the following x-ms-versions

2014-02-14,2013-08-15, 2012-02-12,2011-08-18,2009-09-19.

Also tried to test it as instructed inhttp://blogs.msdn.com/b/cie/archive/2013/08/04/what-s-the-deal-with-x-ms-version.aspx , which also gave me a 400 error.

the response header in Fiddler2 gives this

My aim is to create the virtual machines and manage them using the APIs.

Please help
