root@ubuntu:/home/dong# source /etc/environment 
root@ubuntu:/home/dong# . /etc/environment 
root@ubuntu:/home/dong# echo $CLASSPATH

应该不会有.exe文件，我从ubuntu软件中心装得

[花谢尊前不敢香]

sudo apt-get install openjdk-6-jdk 你没有安装完全。提示那么明显了。

挺聪明啊，这ubuntu太坑了，我是直接java一下它就提示安装，然后直接sudo XXXX，结果就成这样了，明显它装的不全~~~~~~不装了 明天换redhat再装。。。
