Pessoal tenho o seguinte codigo

  System.setProperty("org.xml.sax.driver","org.apache.xerces.parsers.SAXParser");

  try
    {
     JasperDesign jasperDesignRel = JasperManager.loadXmlDesign(statusCad.getSTA_Path_Pastas()+"/WEB-INF/relatorios/relClienteEmpresa.xml");
     JasperReport jasperReportRel = JasperManager.compileReport(jasperDesignRel);

     Map mapParametros = new HashMap();

     JasperPrint jasperPrintRel = JasperManager.fillReport(jasperReportRel, mapParametros , defaultCad.connDados);
     JasperExportManager.exportReportToPdfFile(jasperPrintRel, statusCad.getSTA_Path_Pastas() + "/pdf/relClienteEmpresa.pdf");
     response.sendRedirect("pdf/relClienteEmpresa.pdf");

    }
  catch(JRException er)
    {
     er.printStackTrace(defaultCad.out);
    }

Quando chamo no browser da o seguinte erro
