GWT Spring Jasper Reports Problems

[mariahatie]

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]
