Adding attachments to JIRA REST API using Webmethods as Client

Question

I am probably not the first person trying to add an attachment to JIRA, using JIRA REST API from Webmethods Service. So hoping someone will be able to help.

There are two issues, one with JIRA REST API, two with the Webmethods MIME services(Version 9.8).

Building a addAttachment Service, to add as an attachment a json inputStream to JIRA, using JIRA REST API.

Making use of the following services in webmethods,

pub.string:stringtoBytes.
pub.io:bytestoStream.
pub.mime:createMimeData.
pub.mime:addBodyPart.
pub.mime:getEnvelopeStream.
pub.io:streamToString.
pub.client:http.

The Mime Stream it produces, is as below, (1. Problem 1, Although, in addBodyPart, we are setting the message header to application/json, it seems to be overriding and setting to its own interpretation? 2. Problem 2, although the Boundary is set in the Header to mmmm, Webmethods seems to use its own boundary value) Please can you help resolve this. Can provide with screenshots if required.

    Message-ID: <786753280.135.1438880433399.JavaMail.webm@ruudwmia01>
    MIME-Version: 1.0

    boundary: mmmm

Problem 2, with JIRA REST API, the above mime document as input throws, 415 Unsupported Media Type, from the HTTP POST CALL, to URL, Trying to add an attachment by invoking JIRA REST API.

It is a http client POST call, passing in a mime object - as a stream, the mime stream that is passed in is as ABOVE, Get a 415, Unsupported Media Type Error Message. Nothing in the JIRA Logs.

Try to invoke the service "pub.mime:createMimeHeader" by only setting the input document for the mimeHeader with the following values:

Name=Content-Type Value=multipart/form-data; boundary=mmm

Add your "application/json" header to the "pub.mime:addBodyPart" service with the "contenttype" input-field. Do not set the header in the pub.client:http service.

Take care that you really create a multipart message (at least two parts), else the content-type of the entire message is set to content type of your mime body, as defined in the documentation:

contentype String Optional. The value of the Content-Type header for this body part. For single-part messages, this value overrides the Content-Type value in mimeHeader , if one is present. Defaults to text/plain.

Doing it like this I get the following output:
