Seeburger AS2 - connectivity

Hello,
is it possible to have one single certificate for both AS2 and SSL, using HTTPS protocol.
if yes should we upload the certificates twice (AS2 & SSL)?
Also when we sent some messages via AS2, the seeburger AS2 server seems to be closing the connection abruptly. are there any logs generated on the seeburger side in order to check what actually happened?

Hi
AS2 and SSL follows two different protocols. So It's not possible to use same certificate for both of them.
for AS2 connectivity you can ask your network team to open the network port only for AS2 authentication.

Seeburger AS2 Certificates updates

Dear Experts,
We're having a problem to add in new certificates from our partner. For your info we're using Seeburger AS2 connect and no one knows how to update the certificates including our vendors. Please let me know how to update the certificates. Thank you

Hi,
if you are on PI 7.1x go to Netweaver Administrator (http://server:port/nwa)
Then go to Configuration Management --> Security --> Certificates and Keys
There you shold find several Key Stores ("Key Storage Views")
Select the Keystore which holds the AS2 certificates.
If you are not sure which one is the correct one, check your Sender/Receiver Agreements in the Integration Directory.
The certificates that you specified as TRUSTED\<keystore>\certificate-name in your AS2 configuration are the ones you have to change.
In the "Key Storage View Details" you can add, modify, delete,... the certificates.
regards,
Daniel

Seeburger AS2/SSL Connectivity Error

Dear SAP experts,
I would need your guidance on this one regarding the error that I am getting in our AS2 connectivity with Trading Partner.
The scenario is from SAP XI to Trading Partner.
We are using HTTPS connection. I've already uploaded the SSL certificate of the Trading Partner in the SAP XI Keystore and i've tried to trigger IDocs from XI to TP.
However, i am getting this specific error,
Delivery of the message to the application using connection AS2_http://seeburger.com/xi failed, due to: com.sap.aii.af.ra.ms.api.RecoverableException: Fatal exception: com.sap.aii.af.ra.cci.XIRecoverableException: SEEBURGER AS2: 500 Internal Server Error # , SEEBURGER AS2: 500 Internal Server Error # : javax.resource.ResourceException: Fatal exception: com.sap.aii.af.ra.cci.XIRecoverableException: SEEBURGER AS2: 500 Internal Server Error # , SEEBURGER AS2: 500 Internal Server Error #.
Can somebody advise what causing the error?
Kindly advise!
Thanks!
Godo

Http Error 500 are the most difficult to decipher
You will need to get you Basis to turn on AS2 logs and then check the trace the in the j2ee engine to understand what the error is. Most of the times; the error you see in these logs hits the nail on the head.

Client Auth and SSL with Seeburger AS2 adapter

Hello All,
We are using the Seeburger AS2 adapter in our landscape and I am in the process of setting the same up and have made quite some progress in all my issues.
and I hope that you will be able to help me out.
1. Server SSL on Receiver AS2 adapter
I am sending a message from XI using the Receiver AS2 adapter to my AS2 test tool using Server SSL.
This is working perfectly fine. In my AS2 adapter I have selected HTTPS as the protocol and the message goes via SSL to the target test tool, is processed and the MDN comes back to XI perfectly.
The issue here is :
Irrespective of what is provided in the Server Certificate ( Keystore) , the message goes to my target test tool. I even left this field blank with no certificate entry and still the SSL connection was established and the message went to the target system.
Is there no validation that XI does here? I am lost what is the use of this entry Server Certificate if XI blindly accepts all SSL connections.
I am using a Decentral Adapter Engine with LoadBalancer.
2. Client Auth on Receiver AS2 Adapter
I tried to perform Client Authentication by proving my Server's private key in the AS2 adapter. The corresponding public key is loaded in my partner's Keystore.
XI error's with the error "SSL handshake failed - Bad Certificate" .
I am not sure why XI is erroring out here and I have a feeling that I have misunderstood the use of the fields in the AS2 adapter,
Server Certificate ( Keystore) and Private Key for Client Authentication.
Has anyone tried this? If further details are needed, I will be able to furnish the same.
Regards,
Bhavesh

Hello Jens,
Thanks for your reply.
1. The Encryption and Signature part of the Interface is working absolutely fine and I use the same concept highlighted by you - The Sender always signs the message with his private key and encrypts with message with the partner's public key in the corresponding agreement.
2. Server SSL is also working perfectly fine, i.e, when XI initiates the connection the SSL connection is established to the partner.
3. Mutual Auth was the issue where I was getting the bad certificate issue.
To investigate further I moved the same setup to my Central Adapter Engine and all the issues I had described above seem to have vanished and things work exactly as I was expecting, ie.
The field : Server Certificate (Keystore) is used to provide the Target System's Server SSL's public Certificate.
The field : Private Key for Client Authentication is used where XI provides its own Server SSL's private key for Mutual / Client Authentication.
The problem seems to be with my Decentral Adapter engine and not my central adapter engine and so I guess,
1. I either have the incorrect certificates on my Decentral Adapter Engine.
2. I also have 2 instances of a Decentral Adapter Engine with a Webdispatcher and so maybe the 2 Visual Admin's of the 2 Decentral AE are inconsistent.
3. Maybe it was just a long day and I did something wrong
Will investigate further for the root cause but I am glad that my concepts remain intact and things do work as I expected them to work.
A blog on all this is on the cards sometime soon.
Cheers,
Bhavesh

Error in AS2 RCV adapter.. SEEBURGER AS2: 307 Temporary Redirect #

Hi all,
Iam just doing File to File scenario and passing the resultant file to Partner system through AS2 adapter.
I gave the following details in AS2 RCV adapter..
SND>XI->Webdispatcher--->Partner.
My message will be reached to webdispatcher.. from there it will route to Partner Url.
So i will be giving my webdispatcher URL in my AS2 RCV adapter.

Hi Peter,
>> a, what do you mean with the Web Dispatcher?
We are not using the partner URL directly.We will be using Webdispatcher URL .. from there they have written the rule to goto Partner URL.
>> b, you receive a HTTP code 307, which means that the target AS2 location has been moved. Try to connect the target AS2 server on the URL and check, if it is really there and if it is working.
Looks like this is working.. its showed success state for a while and after few minutes.. its showing the below error in communication channel monitoring.
Delivery of the message to the application using connection AS2_http://seeburger.com/xi failed, due to: com.sap.aii.af.ra.ms.api.RecoverableException: Fatal exception: com.sap.aii.af.ra.cci.XIRecoverableException: SEEBURGER AS2: java.net.SocketException: Connection timed out:could be due to invalid address # , SEEBURGER AS2: java.net.SocketException: Connection timed out:could be due to invalid address # : javax.resource.ResourceException: Fatal exception: com.sap.aii.af.ra.cci.XIRecoverableException: SEEBURGER AS2: java.net.SocketException: Connection timed out:could be due to invalid address # , SEEBURGER AS2: java.net.SocketException: Connection timed out:could be due to invalid address #.
This is the error it is showing in Seeburger Monitoring.

Status Description : Could not deliver as2 message to partner: java.net.SocketException: Connection timed out:could be due to invalid address # null
What is this error?
Do u think there is no problem with AS2 adapter.. its the problem wit webdispatcher.??

Can anyone help me to identify the issue here ?

The certificate of your client must be maintained in AS2 keystore. Make sure that in the receiver agreement, you have given the same name. If certificate name is test.crt, then receiver agreement should have entry AS2keystore\test.

Seeburger AS2 Adapter: "MDN not signed"

Dear all,
we just updated our test system from XI 3.0 to PI 7.1. Now we are facing a problem with our Seeburger AS2 Adapter.
I sent out a message via AS2 and get the follwing error message in Seeburger AS2 Monitor:
"MDN not signed"
In the Receiver Communication Channel I checked the Option "Sign MDN". In XI 3.0 this Scenario was working perfectly. So I contacted our communication partner and asked them if our AS2 message really contained a request for a signed MDN. Our commnucation partner confirmed and sent the MDN as text file to me. This text file shows that the MDN is signed. So it seems that the Seeburger AS2 adapter does not notice that the received MDN is a signed one. But why? Do you have an idea?
Just for testing purposes I unchecked the "Signe MDN" option. In this case the transmission finished successfully.
Who can help?
Thanks
Michael

Dear Vikrant,
many thanks for your reply. But I am not sure if we are really facing the same issue as you described it in your article.
Currently we have this situation:
When I send out a message the Seeburge Workbench provides only the following error message:
"MDN not signed"
Via the Recovery Monitor I can check the received MDN. Here I can see that the MDN is signed and positive.
In the Runtime Workbench I checked the following:
1. In the Message Monitor (Adapter engine) the message is in status "System Error". Here are the details:
Message could not be forwarded to the JCA adapter. Reason: Fatal exception: javax.resource.ResourceException: SEEBURGER AS2: Negative synchron MDN received., SEEBURGER AS2: Negative synchron MDN received.
Adapter Framework caught exception: Fatal exception: javax.resource.ResourceException: SEEBURGER AS2: Negative synchron MDN received., SEEBURGER AS2: Negative synchron MDN received.
Delivering the message to the application using connection AS2_http://seeburger.com/xi failed, due to: com.sap.engine.interfaces.messaging.api.exception.MessagingException: javax.resource.ResourceException: Fatal exception: javax.resource.ResourceException: SEEBURGER AS2: Negative synchron MDN received., SEEBURGER AS2: Negative synchron MDN received..
2. The Communication Channel Monitor shows the following error messages:
Error type: REPORT_ERROR >> Error date: 12/14/10 12:02 PM >> Description: MDN not signed [12/14/10 12:02 PM]
Message processing failed. Cause: javax.resource.ResourceException: Fatal exception: javax.resource.ResourceException: SEEBURGER AS2: Negative synchron MDN received., SEEBURGER AS2: Negative synchron MDN received.
I do not understand why the MDN is recognized as negative and unsigned even if the plain text version of the MDN shows that it is signed and positive.
In your article you recommend to create a sender communication channel for MDN and a corresponding sender agreement. We already did that in XI 3.0 to forward the MDN as STATUS IDOC to SAP ECC.
Maybe you have an additional idea?
Thanks
Michaek
