[resolved] tRESTRequest - Payload Data Not Visible via Http POST method

[Anonymous]

Hi All,
I want to establish and use a Talend REST Service to retrieve and update sensitive information.  
I don’t want this information to be in clear-text in the URI of the service call.  To accomplish this, it is my understanding that the tRestRequest End Point should use the HTTP POST instead of HTTP GET and all sensitive parameters can be delivered as a separate XML payload.
The problem I am having is that the Payload Data coming from the Rest Client is not being referenced properly by the service End Point and therefore not being propagated through the process.  To demonstrate this issue in the simplest fashion, I have constructed a couple of simple Talend jobs. 
Server Job:

<root> <id/></root>                                               <--- Data not propagated to response  
As you can see from the output data above, the data is successfully being passed to the Server with the HTTP POST method but is not being propagated to the response.
For what it's worth, the example in Scenario 3 in the Documention at help.talend.com/display/TalendOpenStudioComponentsReferenceGuide55EN/tRESTRequest basically eliminates the benefits of an HTTP POST request by putting identifying information in URI.  This, in my opinion is no better than an HTTP GET Method.
Please advise..

You don't define the schema of tRestRequest correctly, the data type should be Document and set the same payload structure on tXMLMap as input schema of tRestClient.

Thank you Shong!
Per your recommendations, I was able to get this working by changing the tRESTRequest input schema and tXMLMap in the server job as shown below respectively:
