Bom dia,

Estou tentando gerar um relatório mas o seguinte erro me apresenta:

Alguém pode me dar essa ajuda?

Provavelmente estás serializando algo de forma equivocada, ou esquecendo de fazer um flush() em algum OutputStream.

Posta o código das seguintes classes:

  • GerarRelatorioCertificadoREST
  • RelatorioUtil
#3

Staroski, muito obrigado pela ajuda, ai estão as classes:

@Path("/relatorio")
public class GerarRelatorioCertificadoREST {

@Inject
private GerarRelatorioCertificadoServiceLocal certificadoService;

private static String caminhoRalatorioCertificado = "/relatorios/Certificado.jasper";

private Portfolio portfolio;

@Context
HttpServletRequest request;

private void init() {
    iniciarObjeto();
}

/**
 * Método responsável por iniciar os objetos da classe.
 */
private void iniciarObjeto() {
    portfolio = new Portfolio();
}

@GET
@Path("/pdfCertificado/{idPortfolio}")
@Produces("application/pdf")
public Response downloadCertificado(@PathParam("idPortfolio") Long idPortfolio) throws NegocioException, IOException, JRException {
    init();
    popularPortfolio(idPortfolio);
    RelatorioUtil relatorio = new RelatorioUtil();

    byte[] pdf = relatorio.gerarPdf(request, caminhoRalatorioCertificado, popularParametro());

    ResponseBuilder response = Response.ok((Object) pdf);

    response.header("Content-Disposition","attachment; Certificado " + portfolio.getTurma().getNome() + ".pdf");
    return response.build();
}

/**
 * Método responsável por recuperar o objeto Portfolio.
 * @param idPortfolio
 * @return
 * @throws NegocioException
 */
private Portfolio recuperarPortfolio(Long id) throws NegocioException{
    return certificadoService.recuperarPortfolioPorId(id);
}

/**
 * Método responsável por popular o objeto Portfolio.
 * @param idPortfolio
 * @throws NegocioException
 */
private void popularPortfolio(Long idPortfolio) throws NegocioException {
    portfolio = recuperarPortfolio(idPortfolio);
}

/**
 * Método responsável por popular o parametro do Jasper.
 */
@SuppressWarnings({ "rawtypes", "unchecked" })
private Map popularParametro() {

    Map parametro = new HashMap();

    if(portfolio.getPessoa().getNome() != null) {
        parametro.put("PES_NO_NOME", portfolio.getPessoa().getNome());
    }
    if(portfolio.getTurma().getAtividade().getTipoAtividade().getNome() != null) {
        parametro.put("TAT_DS", portfolio.getTurma().getAtividade().getTipoAtividade().getNome());
    }
    if(portfolio.getTurma().getNome() != null){
        parametro.put("TRM_NO_NOME", portfolio.getTurma().getNome());
    }
    if(portfolio.getTurma().getAtividade().getTipoModalidade().getDescricao() != null){
        parametro.put("TMD_NO_NOME", portfolio.getTurma().getAtividade().getTipoModalidade().getDescricao());
    }
    if(portfolio.getTurma().getAtividade().getHoras() != null) {
        parametro.put("ATV_NU_HORAS", portfolio.getTurma().getAtividade().getHoras());
    }
    if(portfolio.getTurma().getMesDe() != null){
        parametro.put("TRM_DT_MESDE", portfolio.getTurma().getMesDe());
    }
    if(portfolio.getTurma().getMesAte() != null) {
        parametro.put("TRM_DT_MESATE", portfolio.getTurma().getMesAte());
    }
    if(portfolio.getHash() != null) {
        parametro.put("PRT_NO_HASH", portfolio.getHash());
    }
    return parametro;
}

}

public class RelatorioUtil {

 @SuppressWarnings({ "rawtypes", "unchecked" })
public byte[] gerarPdf(HttpServletRequest request, String caminhoJasperResolucao, Map parametrosJasper) throws IOException, JRException {

    InputStream reportStream = request.getServletContext().getResourceAsStream(caminhoJasperResolucao);

    JasperPrint print = JasperFillManager.fillReport(reportStream, parametrosJasper, new JREmptyDataSource(1));
    File pdf = File.createTempFile("output.", ".pdf");

    JasperExportManager.exportReportToPdfStream(print, new FileOutputStream(pdf));

    return JasperExportManager.exportReportToPdf(print);
}

}

#4

Pelo jeito esse seu InputStream não possui o conteúdo de um arquivo .jasper.

InputStream reportStream = request.getServletContext().getResourceAsStream(caminhoJasperResolucao);

Dá uma depurada pra ver o conteúdo desse InputStream.

Exatamente isso Staroski,

O JasperReports guardou uns lixos lá, então fiz o seguinte passo:

  • Alterei no relatório o Strecht Type para RelativeToBandHeight.
  • Dei um Clean, indo no caminho Project > Clean…
  • Removi do jasper o relatório e importei novamente.
  • Renomeei (no Java o caminho tem que ser alterado tmb) e rodei novamente.

Executou perfeitamente.

Muito obrigado Staroski!
