Navegador abri o relatorio

Front-end
#1

galera preciso de uma ajuda, [code] public void pdf() throws JRException, IOException {

    List<Setor> listOfSetor = (List<Setor>) dao.getList();
    JRBeanCollectionDataSource beanCollectionDataSource = new JRBeanCollectionDataSource(listOfSetor);
    String reportPath= FacesContext.getCurrentInstance().getExternalContext().getRealPath("/relatorios/report.jasper");
     
    JasperPrint jasperPrint = JasperFillManager.fillReport(reportPath, new HashMap(),beanCollectionDataSource);
     HttpServletResponse httpServletResponse = (HttpServletResponse) FacesContext.getCurrentInstance().getExternalContext().getResponse();  
    httpServletResponse.addHeader("Content-disposition", "attachment; filename=report.pdf");  
    ServletOutputStream servletOutputStream = httpServletResponse.getOutputStream();  
    JasperExportManager.exportReportToPdfStream(jasperPrint, servletOutputStream);  
    FacesContext.getCurrentInstance().responseComplete();[/code]

esse seguinte codigo gera o pdf e disponibiliza para download, alguem poderia me explicar como fazer para abrir no proprio navegador ?

desde ja abraço

eu uso assim :

[code] public static void startrelatorio(InputStream reportStream, HttpServletResponse response, Map<String, Object> map, JRBeanCollectionDataSource fonteDados) throws JRException, IOException {
byte[] bytes = JasperRunManager.runReportToPdf(reportStream, map,
fonteDados);

    response.setContentLength(bytes.length);
    ServletOutputStream servletStream = response.getOutputStream();
    servletStream.write(bytes, 0, bytes.length);
    servletStream.flush();
    servletStream.close();
    FacesContext.getCurrentInstance().responseComplete();

}[/code]

Cara adptei o codigo, olha se pode me ajudar com esse erro que está dando

[code] public void pdf2() throws JRException, IOException {

    List<Setor> listOfSetor = (List<Setor>) dao.getList();
    JRBeanCollectionDataSource fonteDados = new JRBeanCollectionDataSource(listOfSetor);
    Map<String, Object> map = new HashMap();
    InputStream reportStream = getClass().getResourceAsStream("./relatorios/todosSetores.jasper");
    

    HttpServletResponse response = (HttpServletResponse) FacesContext.getCurrentInstance().getExternalContext().getResponse();

    byte[] bytes = JasperRunManager.runReportToPdf(reportStream, map,
            fonteDados);

    response.setContentLength(bytes.length);
    ServletOutputStream servletStream = response.getOutputStream();
    servletStream.write(bytes, 0, bytes.length);
    servletStream.flush();
    servletStream.close();
    FacesContext.getCurrentInstance().responseComplete();
}[/code]

menos a map, apenas instanciei da seguinte maneira, pois nao tenho parametros para passa,

Tenta passar um parametro no seu mapa…para testar, acho que pode ser isso o problema .
