Tridion 2011 SP1 - Transport service failed to transport - tridion

Question

When I publish I get the following error:
Transport service failed to transport. <Summary state="Failed" referenceId="tcm:0-122-66560"><Error>Transport failed for transaction: tcm:0-122-66560. Error while generating transaction summary.null</Error><Processing><Context topic="Content Delivery"><IsRollbackOnFailure /></Context></Processing><Target /></Summary>
The cd_core.log contains the following:

Check your ..\Tridion\lib\ folder - if the files:
jaxb-api.jar
jaxb-impl.jar
are there, remove them, restart the Publisher & Transport services, and re-test.
