我尝试使用DynamicReports生成动态报告，但始终出现以下异常，有人可以给我解决方案吗？

我的JFrame中有一个JTable和JButton，我需要的是在单击按钮时从JTable的数据中使用DynamicReport（http://dynamicreports.sourceforge.net/）生成报告。
单击按钮时，我要做的是将表模型传递给以下类，并尝试遍历表模型以生成报告。

report()//create new report design

.show();//create and show report
} catch (Exception e) {
e.printStackTrace();
}
}
private JRDataSource createDataSource() {
DataSource dataSource = new DataSource("ID", "Name", "Phone");
for (int i = 0; i < model.getRowCount(); i++) {
System.out.println(model.getValueAt(i, 2));
dataSource.add(model.getValueAt(i, 0), model.getValueAt(i, 1), model.getValueAt(i, 2));
}
return dataSource;
}
}
最佳答案
DynamicReports似乎使用JasperReports，但是您的类路径中两个库的版本可能不兼容。
检查您的DynamicReports版本的文档，以了解期望的JasperReports版本。
