Jasper报告错误：该报告没有Pages

Question

我确信上述类似的问题已被提出，但所提供的答案似乎并未解决或解决我的问题。我调查了this并关注this tutorial on youtube，但一切似乎都很好，但我的应用程序无效。

我在iReport-5.6.0创建了一个报告，它运行正常，我的意思是它按预期显示报告。现在问题出现了，当我想用​​Java代码打开这个相同的报告时...它说“文档没有页面”。

从我的阅读中我了解到这与我的数据源或与此相关的内容有关，但我无法修复它。

我的Java代码

此代码是我用来运行报告的代码。

private void jMenuItem1ActionPerformed(java.awt.event.ActionEvent evt) {                                           
    try {
        conn = con.getConnection();
        JasperReport jasperReport = JasperCompileManager.compileReport(getClass().getResourceAsStream("transrep1.jrxml"));
        JasperPrint jasperPrint = JasperFillManager.fillReport(jasperReport, null, conn);
        JasperViewer.viewReport(jasperPrint);
    } catch (JRException ex) {
        Logger.getLogger(NewJFrame.class.getName()).log(Level.SEVERE, null, ex);
    } finally {
        try {
            conn.close();
        } catch (SQLException ex) {
            Logger.getLogger(NewJFrame.class.getName()).log(Level.SEVERE, null, ex);
        }
    }
}
