When I my report to Excel in iReport, all goes well and apart from my data I get a nice image of my chart. But as soon as I upload my report to Jasperserver and export my report to Excel I get this error saying "File error. Some number formats may have been lost". Even my print date will turn into some strange number.
Can somebody please tell me what I am doing wrong?
It seems that the error was a bit misleading. The server could not handle the date format "EEEEE dd MMMMM yyyy". Hence the error. When that format was changed there was no error message left. That was a completely different situation! Then the parameter "ignoreGraphics" of the file "WEB-INF/applicationContext.xml" on the server was checked and indeed...this was set to true. When changed to false the graphics finally appeared in Excel on the server as well as locally.
