Hi ,
I am using this sample to call my jasper report from my adf application (using jdev 10g ) : http://jdevguru.com/?p=30 .
If my jasper report is without subreport , this sample is working perfect.
I try to add to my report a subreport and from ireport is running correctly but when i call it from my application am getting this error :
