How to publish the {json+headers} to the JMS Queue using JavaScript ?

Hi,

To implement the end to end REST OSB  service  in 12.2, I need your  feedback to how publishing the {json request+ headers } to the JMS  Queue

For asynchronous calls, we want to go through the following pattern:

ProxyService REST > REST pipeline (REST Branch - for HTTP POST) > publish to JMS queue > Proxy (JMS)> Pipeline (---)> BPEL (REST) > OSB (REST)    [OSB > JMS > SOA > OSB][REST]

- >  I don't find the correct implementation to send {JSON request+Headers metadatas}  from the OSB to the JMS Queue that will be consumed by the SOA  BPEL...

Do I have to use the JavaScript function to add the headers in the $body that contain JSON request, to publish the body to the JMS Queue, any examples of that, implementation, please?...
