[SAP PI] 2 Failed messages in AE - SEEBURGER AS2: javax.net.ssl.SSLException: Unrecognized SSL message, plaintext connection? #

Hi, Everyone.

I would like to ask for your help in giving your thoughts about the error I encountered from the messages in the Adapter Engine of PI.

Error: Message could not be forwarded to the JCA adapter. Reason: Fatal exception: javax.resource.ResourceException: SEEBURGER AS2: javax.net.ssl.SSLException: Unrecognized SSL message, plaintext connection? # , SEEBURGER AS2: javax.net.ssl.SSLException: Unrecognized SSL message, plaintext connection? #

Error: Delivery of 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: javax.net.ssl.SSLException: Unrecognized SSL message, plaintext connection? # , SEEBURGER AS2: javax.net.ssl.SSLException: Unrecognized SSL message, plaintext connection? # 

Please note that the message was successfully converted with the mapping in SEEBURGER BICXIADAPTER.

Regards,

Charles Tan
