Bom dia a todos,
Depois de algumas pesquisas sem sucesso, resolvi recorrer a vocês. Necessito criar um projeto em JSF que faça a abertura de arquivos Jasper. Já tenho um Servlet que faz este trabalho para mim, mas gostaria de passa-lo para JSF.
Na tentativa de fazer esta conversão e juntamente com algumas pesquisas consegui gerar o método abaixo que está em meu ManagedBean:
public void openIReports() {
try {
/*Instancia as variaveis*/
vSession = "15914677";
reportName = "XXX";
tpAmbiente = "PRD";
/**/
ServletOutputStream responseStream;
responseStream = response.getOutputStream();
/*Abre a conexão*/
conexao();
//Seta o tipo de aplicação do relatório
response.setContentType("application/pdf");
// Na variavel pathJasper ficara o caminho do diretório para os relatórios compilados (.jasper)
pathJasper = "\\\\Corp01\\Sistemas\\ora_prod\\iReports\\";
System.out.println("Completo... "+pathJasper);
Map parameters = new HashMap();
parameters.put("Title" , reportName);
parameters.put("pSession", vSession );
parameters.put(JRParameter.REPORT_LOCALE, new Locale("pt","BR"));
// Carrega relatório
JasperPrint print = JasperFillManager.fillReport(pathJasper + reportName + "." + reportType, parameters, conn);
//exporta para pdf e exibe no browser sem criar um arquivo fisico em sua maquina
byte[] buffer = JasperExportManager.exportReportToPdf(print);
//define os cabecalhos do header
response.setHeader("Pragma", "");
response.setHeader("Cache-Control", "");
response.setHeader("Expires", "");
response.setContentLength(buffer.length);
//Escreve o relatorio no response
ServletOutputStream ouputStream = response.getOutputStream();
ouputStream.write(buffer, 0, buffer.length);
ouputStream.flush();
ouputStream.close();
response.flushBuffer();
context.responseComplete();
}catch (JRException e) {
e.printStackTrace();
} catch(Exception ex){
ex.printStackTrace();
}
}
Quando o método é executado o erro abaixo é gerado e pelo NetBeans é apontado que o problema esta na linha ouputStream.flush();
