我收到此错误。 如何避免这种异常？ 我在/WEB-INF/lib文件夹下有所有的jar，但是仍然出现此异常。

当我从Eclipse运行该项目时，它运行良好，但是在将其部署到Agile PLM的Tomcat上之后，它给了我上述例外。

Answer 1

检查您是否有任何冲突的jar文件，或者检查lib目录中jar文件中是否存在类javax.xml.rpc.Stub

Answer 2

如果使用WTP（Web工具平台）Eclipse插件，则无需将jars放在/ lib文件夹中。 将所需的jar放入列表后，需要将所需的库添加到部署程序集[Project Properties（Alt + Enter）-> Deployment Assembly]中，Eclipse会将所需的jar放入/ lib文件夹本身。
