ubuntu 安裝java環境

1、安裝jdk：

sudo apt-get install sun-java6-jdk

出現錯誤Package sun-java6-jdk is not available, but is referred to by another package.

解決辦法

sudo add-apt-repository "deb http://archive.canonical.com/ lucid partner"
sudo apt-get update

然後安裝即可成功
sudo apt-get install sun-java6-jdk

2、配置環境變量

sudo vim /etc/environment

在文件里加上

CLASSPATH=/usr/lib/jvm/java-6-sun/lib
JAVA_HOME=/usr/lib/jvm/java-6-sun

CLASSPATH=/usr/lib/jvm/java-6-sun/lib
JAVA_HOME=/usr/lib/jvm/java-6-sun CLASSPATH=/usr/lib/jvm/java-6-sun/lib
JAVA_HOME=/usr/lib/jvm/java-6-sun sudo vim /etc/environment
CLASSPATH=/usr/lib/jvm/java-6-sun/lib
JAVA_HOME=/usr/lib/jvm/java-6-sun 配置 Java環境
sudo vim /etc/environment
CLASSPATH=/usr/lib/jvm/java-6-sun/lib
