Hello, I have an application built in GWT and Spring. I am trying to generate Jasper Reports on the server side. However when I execute the functionality, it hangs/stops at jasperDesign = JRXmlLoader.load(file_name); and does not respond or throw an exception. This means that my RPC call that triggers the report generation function does not return a response either (so the application hangs). However when I run the function in a normal java application it generates a report without any problem. What could be the issue? I am using JasperReports version 5.6.0. My java function: public StandardServerResponse printReport(List<Object> items) { StandardServerResponse response = new StandardServerResponse(); String file_name = null; Map<String, Object> parameters; JasperDesign jasperDesign; JasperReport jasperReport; JasperPrint jasperPrint; try { for (Object obj: items) { parameters = new HashMap<String, Object>(); parameters.put("id_in", obj.getId()); file_name = "G:\myreport.jrxml"; jasperDesign = JRXmlLoader.load(file_name); //application stops here jasperReport = JasperCompileManager.compileReport(jasperDesign); jasperPrint = JasperFillManager.fillReport(jasperReport, parameters, dataSource.getConnection()); JasperExportManager.exportReportToPdfFile(jasperPrint, "G:\report.pdf"); } response.setSuccess(true); } catch (Exception ex) { ex.printStackTrace(); response.setSuccess(false); } return response; }[/code]
