Opa, estou tendo um problema com um NPE. No menu da aplicacao existe um link para um metodo do bean que deveria emitir um relatorio:
public String emitirRelatorioSituacaoAno() {
byte[] stream = null;
try {
FacesContext facesContext = FacesContext.getCurrentInstance();
ServletContext servletContext = (ServletContext) facesContext.
getExternalContext().getContext();
String dirBase = servletContext.getRealPath("");
String caminhoImagem = dirBase + PropertiesUtil.getInstance()
.getResourceBundle("ApplicationConfigurator", "pt", "BR")
.getString("report.image.dir")
.replace("[BARRA]", File.separator);
String caminhoJasper = dirBase + PropertiesUtil.getInstance()
.getResourceBundle("ApplicationConfigurator", "pt", "BR")
.getString("report.jasper.dir")
.replace("[BARRA]", File.separator);
Map parametros = new HashMap();
// parametros.put("SUBREPORT_DIR", caminhoJasper);
parametros.put("IMAGES_URI", caminhoImagem);
stream = ReportUtil.gerarPdfBD(parametros,
caminhoJasper + "report_Denuncia_Situacao_Ano.jasper");
HttpServletResponse res = (HttpServletResponse) facesContext
.getExternalContext().getResponse();
res.setContentType("application/pdf");
res.setHeader("Pragma", "public");
res.setHeader("Cache-control", "must-revalidate");
//Atualizando o status da solicitação
ServletOutputStream servletOutputStream = res.getOutputStream();
servletOutputStream.write(stream);
FacesContext.getCurrentInstance().responseComplete();
return "RELATORIO_SOLICITACAO_EMITIDO";
} catch (IOException ex) {
WebUtil.error(PropertiesUtil.getInstance().getResourceBundle(
"mensagens", "pt", "BR").getString("relatorio_msgErro"));
throw new ApplicationException(ex);
} catch (JRException ex) {
WebUtil.error(PropertiesUtil.getInstance().getResourceBundle(
"mensagens", "pt", "BR").getString("relatorio_msgErro"));
throw new ApplicationException(ex);
}
}O NPE esta acontecendo no metodo “ReportUtil.GerarRelatorioPdfBd”, mais precisamente na linha 5 desse trecho abaixo
public static byte[] gerarPdfBD(Map<?, ?> parametros, String jasperPath)
throws IOException, JRException {
Session session = HibernateUtil.currentSession();
Connection con = session.connection();
JasperReport jasperReport = (JasperReport) JRLoader.loadObject(jasperPath);
byte array[] = JasperRunManager.runReportToPdf(jasperReport, parametros, con);
return array;
}e aqui a pilha de erro:

EDIT:
Estou usando a biblioteca itext-1.3.1.jar e jasperreports-3.0.0.jar. Fiz o relatorio no iReport 3.0.0.
Alguma dica?
