Read RemoteExecutionContext from Azure Queue

Hello,

I worte a plugin that posts a message(CRM Context) on an Azure Queue.

I have to receive that message with a Java application. The message is of type "RemoteExecutionContext".

I wasn't able to find a valid schema for the RemoteExecutionContext sent from MS CRM to Azure Service Bus Queue

I know that you can now specify one of three data formats for the message body: .NET Binary, JSON, or XML. 

but Where to specify?

How can I read that message with Java? 

Thanks in advance.
