galera preciso de uma ajuda,

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();

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 :

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();

    }

    }

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

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();
    }

Abaixo todos as variaveis estão preenchidas ???

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

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

Map<String, Object> map = new HashMap();

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