AS2

Hello,
i hope some of you can help us.
We are trying to use mendelson AS2 to send XML docs to a partner, these are 3 or 4 different PAYLOAD SUBJECTS, but in free mendelson I can't set diferent payloads for same partner, so I tryed by creating 1 different partner for each PAYLOAD SUBJECT, but it forces us to use different AS2 IDs, is there any way to do it with free mendelson?
Thank you.

Tried sending sample data to the testas2.mendelson-e-c.com machine and I think its down. Connections to any outside service works and I tried from various machines from different networks.

It seems like the upgrade does not move the keystore to the new database based on changes made from b65 and on. Does anyone know how to possibly migrate this? If not, where to download older versions? It looks like b59 might be the last version before the database change. Any help would be appreciated. Thank you.

We just did an update to AS2 1.1 build 67 (build date 20/03/25 14:45 and all seems to be working, however, we cannot make modifications to the partners. I.e. a new requirement seems to be to include the port no in the MDN URL, but the OK button remains grayed out. It seems to take it but when you reopen the partner dialog it shows the same issue again, so it is not saving.

We run this on Windows 2008, as a test system.

Sending AS2 message to Partner then return message:
MessageHTTPUploader.performUpload: [ConnectionShutdownException]
How can I find out the detailed cause of the error?

Does the commercial version of Mendelson AS2 support using UNC paths versus mapped drive letters in the community edition?

Local Station MDN URL: https://Host:8443/as2/httpreceiver

(Host= unser Servername ist da natürlich entsprechend hinterlegt)

unser Partner hat diese bei sich auch hinterlegt. Wenn er jedoch eine Nachricht an uns übermitteln will, erhält er folgende Meldung:
Fehler: MDN does not contain AS2-From AS2-To header(s).

I have downloaded the installers from https://sourceforge.net/projects/mec-as2/files/. But after that, I tried to run AS2.jar in my Mac OS but nothing happens. I have java and openwebstart installed in my Mac. Please advise how to proceed.
