SpringMVC模式下的登陆跑不起来

[待解决问题]
之前一直用的是myeclipse做开发，最近公司要求使用eclipse。经常遇到myeclipse可以跑起来的项目在eclipse上面出问题。麻烦有这方面的经验的高手指导一下，谢谢。下面我把代码贴出来
Web页面的报错
1 description The server encountered an internal error that prevented it from fulfilling this request.
控制台的报错

我把eclipse项目里面的代码还有配置文件拷贝到myeclipse里面，就可以正常跑起来。所以这是什么问题有没有人清楚呢，麻烦告知。感激不尽

运行的JDK估计不一样吧
JDK是一样的，在同一台电脑上面
@远歌: myeclipse eclipse有时使用自己内含的JDK，比较下看看；要不就是CLASSPATH不一样
@2012: 因为之前用的是myeclipse做开发，基本上没有接触过eclipse。所以对这个东西不了解
