Java Jasper报告没有显示

我一直在用JAVA在NetBeans7.3IDE上开发一个会计软件

我使用Jasper Report（iReport）在我的应用程序中生成报告。我需要获取填充到

JTable

的特定数据，并仅将这些数据获取到Jasper Report。因此，我使用了

JRTableModelDataSource

在Jasper报告中生成数据

尽管如此，我还是失败了，这意味着，当我点击“显示报告”按钮时，tt并没有显示任何内容，它在NetBeans IDE日志窗口中显示了一个错误

我使用以下代码填充jTable

private void GetGLData(){
    try
    {            
    con = ConnectionManagerACCDAT.getConnection();
    stmt = con.createStatement(ResultSet.TYPE_SCROLL_SENSITIVE, ResultSet.CONCUR_READ_ONLY);
    rs = stmt.executeQuery("SELECT * FROM gl_bt_lst ORDER BY BT_NO ASC" );


    DefaultTableModel dtm = (DefaultTableModel) tblJournalBatchList.getModel();
    Object[] values = new Object[5];
    while (rs.next()) {
        values = new Object[5];
        values[0] = rs.getString("BT_NO");
        values[1] = rs.getString("DT");
        values[2] = rs.getString("DSCRP");
        values[3] = rs.getString("RD_2_PST");
        values[4] = rs.getString("PSTTD");


        dtm.addRow(values);
        }       
    // Close the connection after use
    rs.close();
    stmt.close();
    con.close(); 
    }
    catch (Exception e)
    {
    JOptionPane.showMessageDialog(null, e, "Journal Batch List.", JOptionPane.ERROR_MESSAGE);
    }      
}

我使用以下代码生成报告

private void btnNewActionPerformed(java.awt.event.ActionEvent evt) {                                       
    try
    {            
            String ReportSource = "D:/Reports/Test.jrxml";
            if (new File(ReportSource).exists() == false)
            {
                    JOptionPane.showMessageDialog(null,"Please go to setting and Choose report Source");
                    return;
            }                
            JasperReport jasperReport = JasperCompileManager.compileReport(ReportSource);
            Map params = new HashMap();
            JasperPrint jasperPrint = JasperFillManager.fillReport(jasperReport, 
                    params, new JRTableModelDataSource(tblJournalBatchList.getModel()));
            JasperViewer.viewReport(jasperPrint, false);
    }
    catch (Exception e)
    {                
            JOptionPane.showMessageDialog(null,e,"reports Error  ",JOptionPane.ERROR_MESSAGE);
    }

    // TODO add your handling code here:
}

伙计们，我做错了什么。顺便说一句，我已经将相关库导入NetBeans，并使用字段名称作为列1、列2。。。发射型计算机断层扫描仪。。。将报表链接到jTable列

Jasper Reports有许多您需要包含的第三方依赖项，在这种情况下，您可能需要包含库，但可能还有更多
