在linux里面配置jdk环境变量出现问题

   我昨天在ubuntu里面安装了jdk，配置如下：
安装路径为：/home/administrator/java/jdk1.6.0_14
环境变量配置为：
export JAVA_HOME=/administrator/java/jdk1.6.0_14
export CLASSPATH=$CLASSPATH:$JAVA_HOME/lib:$JAVA_HOME/jre/lib
export PATH=$JAVA_HOME/bin:$JAVA_HOME/jre/bin:$PATH:$HOMR/bin输入：echo $JAVA_HOME
显示：/administrator/java/jdk1.6.0_14
输入：echo $CLASSPATH
显示：.:/administrator/java/jdk1.6.0_14/lib:/administrator/java/jdk1.6.0_14/jre/lib:/administrator/java/jdk1.6.0_14/lib:/administrator/java/jdk1.6.0_14/jre/lib
输入：echo $PATH
显示：/administrator/java/jdk1.6.0_14/bin:/administrator/java/jdk1.6.0_14/jre/bin:/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin:/usr/games:/administrator/java/jdk1.6.0_14/bin:/administrator/java/jdk1.6.0_14/jre/bin:/bin当输入命令：java -version
