Question

在 IBM WAS 6.1 上部署 Spring MVC 应用程序时出现以下错误。

相同的应用程序在 Tomcat + Eclipse 上运行良好。但是当我使用 Rational Application Developer 在 IBM WAS 6.1 上部署它时，我在服务器启动期间收到此错误。

任何人都可以帮我解决这个错误。

提前致谢!

这是一个类加载器问题，看起来与 XSLT ClassCastException in WebSphere when Spring tries to create an AnnotationMethodHandlerAdapter 非常相似。

因此，尝试将类加载器策略设置为 PARENT_LAST 并从应用程序中删除对 xml-apis/xerces/javax.xml jar 的所有依赖项。
