WAS7 中部署spring 应用出错的问题【已解决】

软件名称：
WAS
软件版本：

WebSphere Application Server  试用版

7.0.0.9

环境平台：
windowServer2008 + Orcale10g
项目环境：
底层框架用Spring2.5.6 +JDBC

问题描述：
     WAS7出来之后，一直没怎么用，因为项目上暂时没用到，也就没怎么注意。最近有个项目要启用WAS7做为中间件，所以才从IBM的官网下载了一个试用版。
    完了之后立即部署系统，WAS7在部署这块和之前的6版本好像没什么太大差别，系统成功部署。
   但是启动应用之后，就出现问题了。  spring的配置文件加载不起来了。  
关键错误如下：
