java.lang.UnsupportedClassVersionError: Bad version number in .class file (unable to load class Validator)

你的jdk的版本太低了，换至少jdk 6.0的看看。

你是不是最近安装过 oracle 啊！

[meixqhi]

没有安装oracle，我试试看啊

[meixqhi]

我看了下我的jdk是1.6.0_11的我用的好似MyEclipse7.0的版本，用的很郁闷！

我没有试过，你看下行不行吧

[cuij7718]

肯定是JDK版本问题,如果不确定可以这样

eclipse里面右键单击工程,在菜单中选择java compiler,然后在compiler compliance level 中选择1.5，然后重新部署一下看看

[meixqhi]

谢谢了，我找出来问题了，的确是JDK路径没有设置好，
