执行sudo gedit
/etc/apt/sources.list，

添加以下内容，将10.04的源改成9.04的源。

deb http://run.hit.edu.cn/ubuntu/ jaunty main restricted universe multiverse

deb-src http://run.hit.edu.cn/ubuntu/ jaunty main restricted universe multiverse

deb http://run.hit.edu.cn/ubuntu/ jaunty-updates main restricted universe multiverse

deb-src http://run.hit.edu.cn/ubuntu/ jaunty-updates main restricted universe
multiverse

deb http://run.hit.edu.cn/ubuntu/ jaunty-backports main restricted universe multiverse

deb-src http://run.hit.edu.cn/ubuntu/ jaunty-backports main restricted universe
multiverse

deb http://run.hit.edu.cn/ubuntu/ jaunty-security main restricted universe multiverse

deb-src http://run.hit.edu.cn/ubuntu/ jaunty-security main restricted universe
multiverse

然后sudo apt-get update，再用sudo
apt-get install sun-java5-jdk

安装后的基本设置： sudo update-alternatives
--config java

sudo update-java-alternatives -s java-1.5.0-sun

这时候再用java -version就能看到java
1.5已经正常工作了

最后把源换回10.04的！
