I am using Jasper 5.1 to generate reports in Excel, PDF and Word. Excela and PDF are perfectly ok but the Word file takes too long to open. There are hardly 150 pages and file size is around 1.5 mb.There are no problems with generation of word file but the issue is with opening the file. It takes around 2-5 minutes to open. Below is a snapshot of the code ArrayList<AedbMasterDataBean> records=this.getRecords(); JRBeanCollectionDataSource beanColDataSource = new JRBeanCollectionDataSource(records); JasperPrint print = JasperFillManager.fillReport(jasperMasterReport, parameters, beanColDataSource); JRDocxExporter docxExporter = new JRDocxExporter(); docxExporter.setParameter(JRExporterParameter.JASPER_PRINT, print); docxExporter.setParameter(JRExporterParameter.OUTPUT_STREAM, outputStream); docxExporter.exportReport(); Awaiting your responses MS
