如何解决在WebSphere 8.5.5 Network Deployment上部署Axis2 1.6.2 WebServices时发生异常，javax.servlet.ServletException：java.lang.ClassCastException
我有一个基于JSF的应用程序，该应用程序实现了Axis2 1.6.2 WebServices。该应用程序可与Tomcat正常运行。但是，当我将其部署在WebSphere 8.5.5 Network Deployment上时，启动时会引发异常：

我也将类加载策略更改为“上一父代”，这样我的应用程序的WEB-INF / lib将首先加载。从例外情况来看，似乎Axis2已成功加载，但是依赖项存在一些问题。一个罐子丢失或冲突。
我做了很多研究，但找不到确切的解决方案。有人可以帮我吗，因为我浪费了很多以前的时间来解决这个问题。
