Exp/Imp Problems...

We are trying to export a tablespace 'XYZ' from an Oracle8i Database server to a Oracle 9i Application Server, both
residingon different machines.
 

As far the Export is concerned,we are succesfully able to create the required 'abc.dmp' file on the 8i server.

We then copy the 'abc.dmp' file and the 'XYZ.DBF'(approx. 150 MB) to the machine where the 9i server is located.

And finally when we try to utilise the import utility from the 9i server,it gives us the following messages.
---------------------
