barcode sample couldnot run in 9ias
Oraclebarcode.jar Doesn't work on webserver

I have downloaded the example on how to print a barcode using the oraclebarcode.jar in 9i. It works on my local install of the reportserver(devloper9i), but when I move it out to the webserver(9ias), it doesn't work. It gives this error:

Terminated with error: <br>REP-771: 'beforereport': Fatal PL/SQL error occurred. ORA-39565: Message 39565 not found; product=RDBMS; facility=ORA
the beforreport trigger code below

"
globals.barcode_to_use:=BarCodeConstants.BAR_CODE_128;
"

The jar file is in the reports_classpath, as well as the report. What else to try????
