Question

我正在使用带有Struts 2的Jasper Reports。在我的struts.xml文件中，我已经包含了

 <package name="billingpkg"  extends="struts-default, json-default,jasperreports-default">
    <action name="myJasperTest" class="iland.bill.SubmitBillAction" method="fetchAll">
            <result name="success" type="jasper">
                <param name="location">/pages/billing/Report1.jasper</param>
                <param name="dataSource">list</param>
                <param name="format">PDF</param>
            </result>
    </action>
  </package>

在部署

时显示以下错误

1) Error building results for action myJasperTest in namespace
2) There is no result type defined for type 'jasper' mapped with name 'success'

我已将jasperreport-5.5.0.jar包含在我的类lib

中

如何解决上述错误我得到以下错误堆栈

Answer 1

您需要下载并加入项目JasperReports和struts2-jasperreports-plugin。

从您的评论中看来，您似乎只安装了JasperReports，而不是插件。

另外一定要拿起相同版本的Struts2 jar。

没有为名称为'success'的'jasper'类型定义结果类型
