Re: [ebxmlms-develop] syncReply to return Data structure, Can I use EBXML to encapsulate a Web Service Call?

[Gait B. <gai...@ti...>]

Hi John,

ebXML 2.0 does support syncReply for business messages (payload), but 
Hermes does not AFAIK.
You cannot use the Acknowledgment for this, that's just for reliable 
messaging purposes (Hermes does support syncReply for Acknowledgments 
and Errors, but those are fixed and Hermes generated).

If the sender is not capable of using a HTTP(S) URL for receiving 
messages, you can also use SMTP/POP3. This way you can get around the 
NAT issue.

Hermes gets around the NAT through the client/server architecture, where 
the server is accessible from the internet, and from the client behind 
the NAT. An ebMS endpoint behind a NAT doesn't make a lot of sense...

kind regards, Gait Boxman.
