Hi everybody! I'm facing a very weird problem. I have a desktop application that calls for a .jasper report, simple as that. I works fine, the report is generated perfectly. The problem happens when I try to save as Excel as "Single Sheet" or "Multiple Sheets". On both options, it generates a empty 0 kb file. It's weird because all other option of "Save as" works fine (csv, pdf, etc). I´ve also tried to repeat the problem by generating and saving the report at Jasper Studio, but I couldn't because from there, It worked well too. Bellow are some of code/configurations: 1) Java code that opens the report ..//Java code that opens the report. It's workingJasperPrint print = JasperFillManager.fillReport(dirRelatorio, params, Conexao.getConexao());JasperViewer viewer = new JasperViewer(print, false);viewer.setVisible(true);..[/code]2) Part of my POM file (coudn't find a way to print the dependencies tags, sorry) .. net.sf.jasperreports jasperreports 6.16.0 jar com.oracle.database.jdbc ojdbc8 21.1.0.0 org.apache.logging.log4j log4j-api 2.5 org.apache.logging.log4j log4j-core 2.5 org.apache.poi poi 5.0.0 ..[/code]3) I'm using: JDK 1.8;Netbeans IDE 12.0;TIBCO Jaspersoft Studio-6.16.0 That's it. Any help would be really appreciated
