Jasper报告找不到包net.sf.jasperreports.engine

Question

我有一个使用spring框架的j2ee应用程序.我正在尝试将jasper报告导出为xml,pdf和xhtml文件.我正在使用带有插件的eclipse ide for weblogic server和apache tomcat server.当我在服务器上运行它(在eclipse中)并选择Tomcat作为服务器时,它工作正常.但是当我尝试在服务器上运行它时(在eclipse中)现在选择weblogic服务器我得到一个错误.下面是错误的完整堆栈跟踪

似乎 WebLogic 环境中的类路径中缺少 Jasper Reports 的 jar 之一。检查应用程序服务器的文档，也许您可​​以将其配置为记录类加载操作并获取更多信息来解决问题。我知道如何调试 OC4J 上的类加载问题（我使用 OC4J 并解决了此类问题，启用记录类加载事件并查看日志）。尝试做同样的事情...

我不确定，也许文章“充分利用 WebLogic 类加载器”也对您有帮助。
