Dear Experts,

we have a async/sync bridge configured by using a RequestOnewayBean in a SOAP receiver communication channel which calls a synchronous web service.

However when executing the scenario an 401 error appears in the message log of the adapter engine (caused by the RequestOnewayBean):

com.sap.engine.interfaces.messaging.api.exception.MessagingException: Received HTTP response code 401: Unauthorized.

It looks like the user J2EE_GUEST is not authorized to call the messaging service.

Do you have any idea where this authentication error can be fixed?

Thank you for your advice.
