I have not been able to get a 6i graphic to display using run_Report_object. I turned it in as a trouble call and he suggested I post a question to the Forum, about using JAVA/BEAN to display the graphics/charts.
I know little to nothing of JAVA/BEAN is there anyone willling to share the knowlege and example code.
This forum is mainly for migrating from Oracle to non-Oracle databases and I doubt any participants know about the subject you are asking.
run_Report_object looks to be part of Forms or Reports so it would be better to ask in one of those forums -
