Subject: RE: Use of MIME multipart for zero payload containers
Good point, I agree. In the case of zero payloads, there is no multipart. David Fischer Drummond Group. -----Original Message----- From: Dan Weinreb [mailto:dlw@exceloncorp.com] Sent: Friday, September 14, 2001 10:11 PM To: ebxml-msg@lists.oasis-open.org Subject: Use of MIME multipart for zero payload containers The MS spec seems to say that an ebXML message is always represented as a MIME multipart/related entity. There does not seem to be an exception for the case where there are zero payload containers: in such a case it looks like an ebXML message MUST be expressed as a MIME multipart with only one part. Is that right? I mention this because I was looking at Sun's JAXM EA2 implementation, and it seems to have logic saying that if it finds itself generating a SOAP-with-attachments message with zero attachments, it uses the original SOAP format, which does not use MIME multipart. This means that if you asked it to generate an ebXML message for which there are no payload containers, what it would generate would not be ebXML MS compliant. I brought this up with the JAXM group and got this response: Date: Fri, 14 Sep 2001 15:04:12 -0700 From: Nicholas Kassem <nick.kassem@sun.com> Dan, Once again thanks for your input. I believe I now understand your point. In the JAXM context I don't think we will gain much by dwelling on the *interpretation* of the numerous relevant specs. The key issue is what is the canonical form of an ebXML 1.0 message in cases where there is only one part in a multipart/related message. Your contention is that the presence of an empty attachment (equivalent to no ebXML payload) may lead to interoperability problems. I'm not convinced, but be that as it may. So, we will include a facility in JAXM to *explicitly* use multipart/related packaging even in cases where it is logically redundant. Hope this helps.
