在这里我无法解决问题的日志文件。
我重新启动了Web服务器，
清洁了项目并尝试重建，但仍然没有运气来理解到底出了什么问题。
我尝试通过删除冲突的JAR文件来搜索SOF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。

INFO: Server startup in 19743 ms看起来可能是类加载问题。在TOMCAT类加载层次结构中，Icefaces Jar是否包含多个级别？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.UTIL.ENVUTILS类中的isCoallesCereSources。现在，这两个类应该在同一iCefaces jar文件中，因此应在兼容版本中。但是，该方法不在当前已加载的Envutils类中（请注意，该方法是在IceFaces 3.3中添加的，但还添加了CoeleScingResourceHandler类。因此，看来Eventutils类似乎是从iCefaces Jar文件中与版本3.3一起加载的，而CocatingResresourceHandler类是从版本3.3或更高版本的IceFaces JAR文件中加载的。
。确保tomcat类加载层次结构中的所有icefaces.jar文件均具有相同的版本，或者更好的是，确保jar文件不会在层次结构的一个级别以上显示。
