We have a Java EE aplicattion, JRE 6, MySQL 5.5, running on Tomcat 5.5. We have several JR reports working right but there is one of them that causes the following Tomcat error:

The method to generate the report is this (uncomplete, only the call and few more things):
private void generarReporte(List info,
InformeGestionFormBean gestionBean,
HttpServletRequest request,
HttpServletResponse response,
String descripDispo) {
try {
ServletOutputStream out = response.getOutputStream();
String centro = descripDispo;
String imagenlogo = ".." + File.separator + ".." + File.separator + "images" + File.separator + "logo2.jpg";
String imageninforme = ".." + File.separator + ".." + File.separator + "images" + File.separator + "finforme.jpg";
String imagenflecha = ".." + File.separator + ".." + File.separator + "images" + File.separator + "flecha.jpg";
String ruta = ".." + File.separator + ".." + File.separator + "iReport" + File.separator;
Map parametros = new HashMap();
parametros.put("TITULO", "INFORME CUADRO DE GESTION DE "+centro+"");
parametros.put("FECHA_ANYO", gestionBean.getAnioPeriodo());
parametros.put("CENTRO", centro);
parametros.put("IMAGEN_LOGO", imagenlogo);
parametros.put("IMAGEN_INFORME", imageninforme);
parametros.put("IMAGEN_FLECHA", imagenflecha);
parametros.put("SUBREPORT_DIR", ruta);
InputStream is = null;
String header = "";
is = InformeGestionAction.class.getClassLoader().getResourceAsStream(ruta + "InformeCuadroGestion.jrxml");
header = "attachment; filename=\"InformeCuadroGestion";
JRExporter exporter = null;
JasperReport reporte = JasperCompileManager.compileReport(is);
JRDataSource aux = new JRBeanCollectionDataSource(info);
JasperPrint jasperPrint = JasperFillManager.fillReport(reporte, parametros, aux);
This report worked fine few weeks ago, but now it doesn't. I've tried using code from the backup from the time when it worked ok, but the problem is still there. Maybe I changed configuration or something, I don't know.
