getjobid Randomise

We have Oracle Forms and Reports 11gR2 Application (Windows 2008) with Standalone reports server configured and the application extended to external customers. Users generate various reports.

however whenever a report is generated, the url is dispalyed with the job id ( http://10.20.20.10:8888/reports/rwservlet/getjobid9573 ).

the job id is sequential and easily one can see other users reports by changing the jobid number which is a data protection issue for us.

I tried setting the registry entry REPORTS_JVM_OPTIONS=-Djobid=random

I tried the rwserver.conf "jvmOptions=-Djobid=random"

however it is not making any difference whatsoever and the jobids are still sequentional and easily identifiable.
