Hi, I have a problem with exporting to multiply .xlsx sheets. Ive made report in JasperReports and everything works fine on Jasper. But when I upload jasper template on ART 2.5.1 and this functionality doesnt work. I download output.zip file from topic that explane how to setup this kind of export. Then I rename those files with a names which are on my server: 1. jasperOutput$1.class 2. jasperOutput$2.class 3. jasperOutput.class 4. jasperOutput.java Then restart tomcat... and this export doesnt work....
