You shouldn't have that problem if you are using the 11g release.
Verify if you have the MessageInfo interface. MessageInfo (Oracle Fusion Middleware User Messaging Service 126.96.36.199.0 Java API Reference)
Thank Daniel for the reply.
But what is the impact user messaging service has here. Can it happen that my oracle.tip.adapter.file.outbound.FileIoInteractionSpec is corrupted?
