Problem displaying PDF with Jasper Reports

Question

I have the following code that loads a report and displays it in PDF format:
if(jasperReport==null) {
     logger.debug("Loading...");
     InputStream inStream = null;
     try {
          inStream = getServletContext().getResourceAsStream("/WEB-INF/reports/UnitReport.jasper");
          logger.debug("got inStream");
          jasperReport = (JasperReport) JRLoader.loadObject(inStream);
          logger.debug("Loaded compiled report");
     } catch(Exception e) {
          logger.error(e.getMessage(),e);
     } finally {
          try { inStream.close(); } catch(Exception e) {}
          logger.debug("closed");
OutputStream outStream = null;
Connection conn = null;
try {
     logger.debug("Start build");
     LoginInfo lInfo = (LoginInfo) request.getSession().getAttribute("LoginInfo");
     logger.debug("got name: " + lInfo.getFullName());
     String unitID = (String) request.getParameter("unitID");
     response.setContentType("application/pdf");
     outStream = response.getOutputStream();
     logger.debug("set content type & got OutputStream");
     JRExporter exporter = new JRPdfExporter();
     logger.debug("new exporter");
     conn = DBConnection.getDBConnection();
     logger.debug("got connection");
     //Setup parameters
     Map<String, Object> params = new HashMap<String, Object>();
     params.put("unitID", new Long(unitID));
     params.put("userName", lInfo.getFullName());
     if(debug) {
          logger.debug("set parameters: ");
          logger.debug("  Unit ID:    " + unitID);
          logger.debug("  User Name:  " + lInfo.getFullName());
     JasperPrint jasperPrint = JasperFillManager.fillReport(jasperReport, params, conn);
     logger.debug("built report");
     exporter.setParameter(JRExporterParameter.JASPER_PRINT, jasperPrint);
     exporter.setParameter(JRExporterParameter.OUTPUT_STREAM, outStream);
     logger.debug("set output parameters");     
     exporter.exportReport();
     logger.debug("dumped.");
} catch(Exception e) {
     logger.error(e.getMessage(),e);
} finally {
     try {outStream.close(); } catch(Exception e) {}
     try {conn.close(); } catch(Exception e) {}
     logger.debug("cleanup done.");
}This works fine locally but when I deploy the EAR file to the production server I get the following:
