Question

我正在尝试使用Java应用程序来生成在iReport中创建的报告。我的代码如下：

    Connection conn = (Connection) new OracleCon().getConnection();
    System.out.println(conn);
    Map<String, Object> param = new HashMap<String, Object>();
    param.put("PARCLOCADOR", "47");
    System.out.println(param);
    try {
        //conectar com o banco de dados
        JasperPrint jp = JasperFillManager.fillReport("src/report/RelacaoRendimentos-DIMOB_NEW.jasper", param, conn);
        System.out.println(jp);
        JasperViewer jw = new JasperViewer(jp);
        jw.setVisible(true);

    } catch (JRException e) {
        e.printStackTrace();
    }

我有这些例外：

Exception in thread "main" java.lang.NoClassDefFoundError: org/apache/commons/logging/LogFactory
at net.sf.jasperreports.engine.JasperFillManager.<clinit>(JasperFillManager.java:81)
at com.geraRelatorio.CreateReport.main(CreateReport.java:46)
Caused by: java.lang.ClassNotFoundException: org.apache.commons.logging.LogFactory

at java.lang.ClassLoader.loadClass(Unknown Source)
at sun.misc.Launcher$AppClassLoader.loadClass(Unknown Source)
at java.lang.ClassLoader.loadClass(Unknown Source)
... 2 more

它可以工作到这里：“ System.out.println（param）;”

我正在使用的所有库都在这里：

ojdbc8.jar
SankhyaW-extensions.jar
SWService.jar
