I was creating two diagrams in jasper reports studio 6.12 (one PIE other CHAR) and I was creating one basic reports with 2 subreports
(one PIE on the left side, other CHAR in the right side) and in the preview, I can see both diagrams.
The problem begins when I publish a report with this 2 subreports on jasper report server 7.5 (manually install as war file)
Jasper reports server 7.5 display PIE and CHAR as alone reports, but basic reports which have 2 subreports
give me error in log server file
