I 'm using jasper server v4.7.1 and ireport v4.7.0.
I use rest v2 to call report on jasper server as pdf file as below.
I found the problem that I connot detect when report has no record. It always return pdf file to me. In case of no record , I got pdf file as blank page.
Note : I set the property 'When No Date' as 'No Pages' in report
