[问题]在ubuntu中用eclipse编写java程序，能通过编译，但是不能运行。

[shinsy]

简单的程序直接用CTRL＋F11就可以运行了，但是稍微复杂一点的程序就会报错。

我的java版本是1.6.0

但是我在命令行状态下，输入sudo java Practice10
程序就会正确运行。如果不加sudo，会输出象上面一样的错误。
我曾试着给eclipse和/usr/lib/jvm/sun-java-6/jre/bin/java 加上S权限，但是行不通，eclipse直接就不工作了。头痛啊。！

我切换到管理员帐户运行也会出错！

注：CLASSPATH应该是设对了（修改了environment文件），不知道有没有方法让我确定自己设对了。
