XSLT Transformation Filter Removes The Content ID In Multipart Messages (Doc ID 1592139.1)

Last updated on AUGUST 18, 2016

Applies to:

Oracle API Gateway - Version 11.1.2 and later
Information in this document applies to any platform.

Symptoms

Oracle API Gateway (OAG) 11.1.2.1.0 or 11.1.2.2.0.

In a multipart message, there is an optional sub-component of the content-type header called "start" which points to the first main body part of the multipart message.
This "start" parameter contain a Content-ID, which is also in the multipart parts of the main body, like this:

Content-Type: multipart/related; boundary="MIMEBoundary_c46b02ecf074e1b835adf738b0e6469b25a0b72789bc6407"; type="application/soap+xml"; start=""; action="ebms3"
[...]
--MIMEBoundary_c46b02ecf074e1b835adf738b0e6469b25a0b72789bc6407
Content-Type: application/soap+xml; charset=UTF-8
Content-Transfer-Encoding: binary
Content-ID:


When the problem occurs, the Content-ID header inside of the MIMEBoundary is missing.

This then causes a variety of further error messages from libxml.

The problem shows up only when an XSLT Transformation Filter is used.

Changes

The problem does not occur with OAG 11.1.2.3.0.
