Question

我有一个项目，我正在使用jasper报告来创建报告，我使用的是4.2版本。

当我在tomcat上运行这个项目时它运行正常，但是当在weblogic上部署相同时，我得到以下错误：

2017-01-23 19:40:18,520 ERROR [org.apache.commons.digester.Digester] - <Parse Error at line 2 column 434: Document root element "jasperReport", must match DOCTYPE root "null".>

Weblogic正在使用自己的旧版jasper报告jar。我尝试通过在weblogic.xml中添加以下代码来配置我的war文件应该使用自己的jar，

<container-descriptor> <prefer-web-inf-classes>true</prefer-web-inf-classes> </container-descriptor>

但它不起作用我通过在weblogic服务器上添加新版本的jasperreport jar解决了这个问题，并给出了相同的类路径。

获取错误文档根元素“jasperReport”必须与DOCTYPE根“null”匹配
