如何在 Myeclipse IDE 中修复这些与 jsf 和 spring 的 Jar 文件和 lib 相关的小错误

Question

这里是我无法解决问题的日志文件。

我已经重启了网络服务器，

清理了项目并尝试重建，但仍然无法理解到底是什么问题。

我尝试在 SOF 上搜索以通过删除冲突的 jar 文件来解决问题，但仍然没有成功。

任何人都可以理解下面的日志文件。

看起来可能是类加载问题。 icefaces jar 是否包含在 Tomcat 类加载层次结构的多个级别中？查看堆栈跟踪，org.icefaces.impl.application.CoalescingResourceHandler.RegisterListener 类中的 processEvent 方法正在调用 org.icefaces.util.EnvUtils 类中的 isCoallesceResources 方法。现在，这两个类应该在同一个 icefaces jar 文件中，因此应该是兼容的版本。但是，被调用的方法不在当前加载的Envutils类中（注意，该方法是在icefaces 3.3中添加的，当时还添加了CoelescingResourceHandler类）。所以看起来 EventUtils 类是从 3.3 版之前的 icefaces jar 文件加载的，而 CoalescingResourceHandler 类是从 3.3 或更高版本的 icefaces jar 文件加载的。

确保Tomcat class loading hierarchy 中的所有icefaces.jar 文件都具有相同的版本，或者更好的是，确保该jar 文件不会出现在层次结构的多个级别中。
