很菜的我今天在LE2005上安装 JDK 的经历，希望能给大家提供些帮助。

今天安装了一下 JDK jdk-1_5_0_03，本来想在java.sun.com下载可是不知道是怎么回事在公司与在家都不能下载是在是郁闷啊，在 JAVA坛子上发了个帖子求助好心的JAVA版主fei给了他的ftp下载地址感谢他提供这么快的FTP服务器，下面是下载地址。

ftp://202.96.64.144/pub/jdk-1_5_0_03-linux-i586.bin

下载回来以后复制到 /usr/local 中 然后执行 chmod 755 jdk-1_5_0_03-linux-i586.bin 这样就可以运行了，否则有可能无法运行的说。。。。。。


接着敲 ./jdk-1_5_0_03-linux-i586.bin 然后会弹出

按几下空格以后会出现下面的话

Do you agree to the above license terms? [yes or no]

问你是否接受协议，一定要敲 y 并且按回车不然不让装哦！
接着提示 Unpacking... 开始解压并开始安装

等到出现
Creating jdk1.5.0_03/lib/tools.jar
Creating jdk1.5.0_03/jre/lib/rt.jar
Creating jdk1.5.0_03/jre/lib/jsse.jar

Creating jdk1.5.0_03/jre/lib/plugin.jar
Creating jdk1.5.0_03/jre/lib/javaws.jar
Creating jdk1.5.0_03/jre/lib/deploy.jar

Done.

的时候就安装完毕了，接下来就是设置系统了。
看JAVA坛子里面的帖子说是要如下设置，经过实验发现不行。。。。
编辑 .bashrc 文件加入
set JAVA_HOME=/usr/java/j2sdk1.4.2_06
export JAVA_HOME
set PATH=$PATHJAVA_HOME/bin
export PATH
set CLASSPATH=.JAVA_HOME/lib/dt.jarJAVA_HOME/lib/tools.jar
export CLASSPATH


重新启动系统多次也未见好使，最后发现那三个 set 是多余的，改成下面的就 OK 了！  :!!

JAVA_HOME=/usr/java/j2sdk1.4.2_06
export JAVA_HOME
PATH=$PATHJAVA_HOME/bin
export PATH
CLASSPATH=.JAVA_HOME/lib/dt.jarJAVA_HOME/lib/tools.jar
export CLASSPATH

一会再去弄个IDE装上玩玩......

谢谢！也许过几个月就有用了！呵呵，我们要开Java课程了。

用“set"好像是在别的linux版本有用。我也是上了这个当，呵呵。
