虚拟机一定要安装英文版的，要不然恶心死你！！！
[root@xhw48 weblogic]# mkdir /usr/java
必须把 jdk-6u7-linux-i586.bin拷贝到/usr/java进行解压和安装，这是标准的安装位置，虽然其他位置也不会影响到使用。
[root@xhw48 java]# pwd
/usr/java
[root@xhw48 java]# ll

[root@xhw48 java]# ./jdk-6u7-linux-i586.bin
在按提示输入yes后，jdk被解压。

出现一行字：Do you aggree to the above license terms? [yes or no]
