XML WorkFlow Loader - Plz help

hi

i've got a problem in Uploading Business Event System XML Definitions to a Database using the command - oracle.apps.fnd.wf.WFXLoad -u[f] <user> <password> <connect_string> <protocol> <lang> <source_file> .
Running it in Unix env at command prompt it says - "NO object is loaded to the database...".
What can be the possible solution to resolve this issue.

Awaiting a response at the earliest..
