Hi, I have the same problem. It is no problem to fill report, but when I am exporting report, is problem with heap space. Swap file is not solution, because it can help only with filling report, not exporting. Any suggestions, please? Thanks Michal Code:JExcelApiExporter exporter= new JExcelApiExporter(); exporter.setParameter(JRXlsExporterParameter.IS_REMOVE_EMPTY_SPACE_BETWEEN_ROWS, Boolean.TRUE); exporter.setParameter(JRXlsExporterParameter.IS_ONE_PAGE_PER_SHEET, Boolean.TRUE); exporter.setParameter( JRXlsExporterParameter.IS_DETECT_CELL_TYPE, Boolean.TRUE); exporter.setParameter( JRXlsExporterParameter.IS_WHITE_PAGE_BACKGROUND, Boolean.FALSE); exporter.setParameter( JRXlsExporterParameter.IS_REMOVE_EMPTY_SPACE_BETWEEN_ROWS, Boolean.TRUE); exporter.setParameter(JRExporterParameter.JASPER_PRINT, jpv); exporter.setParameter(JRExporterParameter.OUTPUT_FILE_NAME, Enviroment.DIRECTORY_PRINT_TEMP + File.separator + nazovVystupu + "_" + TIME + ".xls"); //Pass the sheet names exporter.setParameter(JRXlsExporterParameter.SHEET_NAMES, nazvyZositov); exporter.exportReport();
