Configuring for Response (Outbound or Fault) Flow

You can configure outbound messages sent from a service by configuring the following:
  • Supported Type: Basic, Bag
  • Supported Header Source: HTTP_HEADERS
  • Direction: Outbound / Fault

Add the following code.

To set a 'Basic' context parameter: 

//Create a Mutable callbackContext (Response flow) from the original RequestContext
MutableCallbackContext originalCallbackContext = (MutableCallbackContext) originalRequestContext.createCallbackContext();

originalCallbackContext.setParameter("bookCategoryCP", String.class, "Classic");

The value Classic is set for the HTTP Header bookCategory (corresponding to the context parameter bookCategoryCP) in the outgoing REST Response.

To set a context parameter 'Bag' : 
//Create a Mutable callbackContext (Response flow) from the original RequestContext
MutableCallbackContext originalCallbackContext = (MutableCallbackContext) originalRequestContext.createCallbackContext();

HashMap<String, String> responseHeadersAllCP_service_map = new HashMap<String, String>();
responseHeadersAllCP_service_map.put("bookAuthor", "Harper Lee");
responseHeadersAllCP_service_map.put("bookPublishYear", "1960");
originalCallbackContext.setParameter("responseHeadersAllCP", Map.class, responseHeadersAllCP_service_map);

The contents of the HashMap responseHeadersAllCP_service_map will be set as HTTP Headers (user-defined, corresponding to context parameter responseHeadersAllCP) in the outgoing REST Response. Setting native HTTP Headers is not permitted.
