我刚试过 Jasper Report,我正在学习来自 this site 的教程

我还下载了示例源然后运行它并且没有出现错误。但是,当我使用 iReport 创建自己的报告时,编译它,并将 .jasper 文件添加到我的项目中。当我运行我的程序时出现异常:

这是我用于显示报告的按钮操作(这只是示例,报告仅包含一个带参数的文本:outputText):

Map params = new HashMap();
params.put("outputText", "Hello world");
try {
JasperPrint printer = JasperFillManager.fillReport(getClass().getResourceAsStream("report2.jasper"), params, new JREmptyDataSource());
JasperViewer jv = new JasperViewer(printer);
jv.show();
} catch (JRException ex) {
ex.printStackTrace();
}

如果是 dependency 问题,我已经将所有必需的 jar 导入到我的项目中,当我使用该教程中的 .jasper 文件时没有问题,是吗是因为 iReport 版本不同还是其他原因?
