那到底是哪个文件在打开时发生错误了呢？一头雾水了吧，汗。。。估计你会。。。

分析：
1、通过对文件的排查，确认排除了应用程序中引用jar文件损坏的可能性以及由于jar文件权限设置导致无法读取的可能性

2、打开跟踪日志级别进行剖析

Java代码 复制代码
  1. Application servers > memXXX > Logging and Tracing > Change log detail levels  
复制代码
1
2
Application servers > memXXX > Logging and Tracing > Change log detail levels


设置ClassLoaderUtils跟踪级别如下

Java代码 复制代码
  1. *=info: com.ibm.ws.classloader.ClassLoaderUtils=finest  
复制代码
1
2
*=info: com.ibm.ws.classloader.ClassLoaderUtils=finest


重新启动后，在trace.log里可以发现如下信息

继续分析：
首先，可以确认的是WARNING所报的是正确的，因为可以通过确认所依赖的log4j.jar log4j-core.jar jakarta-oro.jar struts-legacy.jar之类的文件不存在。
其次，这些不存在的包是由谁依赖并需要加载的，通过日志的层次关系可以知道，commons-logging.jar需要log4j.jar log4j-core.jar，struts.jar需要jakarta-oro.jar struts-legacy.jar
这样唯一的可能就是各自的jar包中META-INF/MANIFEST.MF里声明了这些jar的依赖关系了。

打开commons-logging.jar，发现其中的META-INF/MANIFEST.MF里包含了
Class-Path: log4j.jar log4j-core.jar

打开struts.jar，发现其中的META-INF/MANIFEST.MF里包含了
Class-Path:  commons-beanutils.jar commons-collections.jar commons-dig
ester.jar commons-logging.jar commons-validator.jar jakarta-oro.jar s
truts-legacy.jar

于是真相大白了，解决的办法要么增加相应版本所依赖的jar包，要么就是简单地删除Class-Path，根据应用程序的需要进行确认并使用之，[color=red]建议用前者进行解决。要么就升级这些组件包。[/color]

不厚道，在Manager.Ffdc.log里把jarFileName也打印出来，就更容易知道是什么问题了。
可见打印出有意义的信息对于分析问题是多少的重要。。。

附带信息：将commons-logging.jar与struts.jar与Spring 2.5.5发布所带的包进行对比分析，发现Spring带的commons-logging.jar包没有带有Class-Path这个条目。
