Question

我刚试过Jasper Report，我正在关注this site

的教程

我还下载了示例源，然后运行它并没有出错。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。我运行程序时有exception：

这里是我用于显示报告的按钮操作（这只是示例，报告只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，是不是因为{的iReport版本不同{1}}或者其他？

Answer 1

或者，您可以更改.jrxml文件，查找

language="groovy"

并将其更改为

language="java"

Answer 2

可能是因为版本不匹配。如果你想知道你需要哪个版本的Groovy，你可以看一下Jasper的Maven资源库：

http://mvnrepository.com/artifact/net.sf.jasperreports/jasperreports/4.6.0

从这里您可以看到 Jasper 4.6.0

需要 Groovy 1.7.5

Answer 3

使用CallSiteArray类需要额外的Jar包。

http://groovy.codehaus.org/Download

Answer 4

我在使用Jasper iReport Tool 5.6.0时遇到了同样的问题我将语言作为Java，而正确的jasper报告库我将其归类为iReport Tool 5.1.0，它的工作方式就像魅力一样...希望状态仍然存在所以..

Answer 5

无需更改库，如果是Ireport 5.X版本，您可以在主报表属性的语言部分更改它，只需从groovy更改为java并且报告不会出现任何错误。

Answer 6

简单的回答

<强>步骤进行：

1 从报告检查器中选择您的根文件夹，即report1.jsxml （ Windows-＆gt;报告检查器） 2 转到属性标签，然后点击语言标签，然后选择JAVA

编译并预览您的应用程序...

对subReports执行相同操作

为什么我会得到异常java.lang.NoClassDefFoundError org / codehaus / groovy /？
