AS2 Standard

[Peter Connell <Peter.Connell@xxxxxxxxxx>]

   Hi Scott,


   I recently posted to the midrange-L list about a *SRVPGM not being
   found during the loading of java classes while I was investigating
   using an open source AS2Secure package from a crowd going by the name
   of mendelson . In your response you mentioned -

   <<<

   I'm not familiar with AS2eSecure.  Is this a 3rd party tool?

   >>>


   The query was in reference to implementing messaging via the AS2
   standard (typo s.b. AS2Secure) which I now see you have in fact
   implemented according to your FTPAPI response at

   There is a lot of blurb about AS2 which our govt partner has supplied
   for reading but I want to cut to the basics because, like a lot of
   protocols, you don't need to know how the airplane works, just which
   controls to press in the cockpit.  AS2 seems a bit weird and complex if
   one is used to straight forward messaging using something like HTTPAPI
   so I wonder if you can cut thru the crap for me coz I don't have much
   time to evaluate now.


   Despite us now communicating with partners largely in xml, the gist of
   AS2 seems to be a message that is sent as what is essentially a
   multi-part form with the xml request required by our partner embedded
   as an encrypted payload and the whole thing signed. I think I
   understand that but am I correct in that, with AS2, the request and
   response are essentially 2 separate transactions. We initiate a
   connection to our partner's HTTPS server and send a request (which they
   decrypt and verify the signature). Our partner subsequently initiates a
   separate connection to one of our HTTPS servers and sends a response
   (which we decrypt and verify the signature)  Then there is mention of
   these MDN things.  Are MDNs what one is expected to receive as the
   response during the initial connection that are simply a notification
   of success?


   I've found that the AS2Secure package runs very slowly as java on the
   i5 and that it may be better to run it on a Windows server using mapped
   folders like you mentioned since that appears to be fairly quick
   despite having to poll the IFS every second.


   Cheers, Peter
