在NetBeans中使用子报表时出现问题无法使用NetBeans的问题子报告

Question

我在尝试运行带有子报表的报表时遇到了麻烦，NetBeans中仅显示主报表数据，而在iReport中，它同时显示主报表和子报表。我认为问题出在子报表地址上，您应该如何正确告知他们？

解决方案执行主体和解决方案主体之间的关系，无NetBeans的主体问题，无iReport报告权的主体或解决方案主体。是信息通报公司，还是信息通报公司？

我的报告是一个名为“ reports”的程序包，其中所有我的.jasper文件都在其中。我尝试过多种输入路径的方法：通过iReport的InputStream，URL和String，但是没有显示子报表数据的方法，我在几个地方进行了浏览，没有建议的解决方案，我按照本教程进行操作以下。子报表：jasperreports-working-with-reports-in-java-parte-3-subreports

在本地更新或更新文本，或在.jasper上运行。通知格式：在InputStream上输入URL，在iReport上输入URL字符串，在URL上添加字符串，然后在foss exibidos上添加字符串，在procaros上注册并保存下来的文本， subrelatórios：jasperreports-trabalhando-com-relatorios-em-java-parte-3-subrelatorios

代码/CódigoJava：

FichaTecnica fichaTecnica = (FichaTecnica) jCBFichaTecnica.getSelectedItem();

        Connection con = ConnectionFactory.getConnection();

        InputStream reportFile = getClass().getResourceAsStream("/relatorios/SC.jasper");

        JasperPrint jp = null;

        try {
            HashMap parametros = new HashMap<>();
            parametros.put("id", fichaTecnica.getIdFichaTecnica());
            parametros.put("cf", jTFixo.getText());
            parametros.put("cv", jTVariavel.getText());
            parametros.put("q", jTQuantidade.getText());
            parametros.put("ci", jTResultadoCI.getText());
            parametros.put("p", jTPorcentagemLucro.getText());
            parametros.put("preco", jTPreco.getText());

            jp = JasperFillManager.fillReport(reportFile, parametros, con);
            JasperViewer jv = new JasperViewer(jp, false);
            jv.setTitle("Relatorio - Simulador de Custos");
            jv.setIconImage(Toolkit.getDefaultToolkit().getImage(MaterialREPORT.class.getResource("/imagens/real.png")));

            jv.setVisible(true);

        } catch (JRException ex) {
            Logger.getLogger(SimuladorCustosVIEW.class.getName()).log(Level.SEVERE, null, ex);

不幸的是，没有返回明确的错误，仅不显示子报表的内容，我希望两者都出现，这样我的报告才有意义。如果有人花一点时间来帮助我，我将不胜感激。如果您需要更多信息，请询问。

Infelizmente，néoédevolvido nenhum erro claro，apenas oconteúdodossubrelatóriosnãoéexibido，o meu desejoéque ambos aparecessem para que assim o meurelatóriofizesse sendido。 Ficaria grato sealguémtirasse um pouco de tempo para me ajudar。 Caso necessite de maisinformationaçõesésópedir。
