AS2 Receiver channel error

Hi Experts,

I am encountering an error in AS2 receiver channel:

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: HTTP-Client component init failed # java.security.PrivilegedActionException: com.seeburger.ksm.cryptoapi.exception.CryptoApiException: Could not retrieve alias collection., SEEBURGER AS2: HTTP-Client component init failed # java.security.PrivilegedActionException: com.seeburger.ksm.cryptoapi.exception.CryptoApiException: Could not retrieve alias collection..

I checked some blogs and it all suggested to check the sender/receiver agreements and AS2 ID's.

I can confirm that my sender/receiver agreements are properly configured and the AS2ID's are setup in the sender/receiver party and the communication channels.

Any help regarding this is highly appreciated.

Thanks,

Mike
