ubuntu下安装JDK6 续

之前总结的Ubuntu下手动安装方法还是有很多纰漏……比如说javac,javadoc这种指令还要手动设置等等……其实只要你有一台能联上外网的机器，用apt-get install安装还是轻松加愉快的……apt-get install sun-java6-jdkupdate-alternatives --config javanano /etc/environment添加：CLASSPATH=.:/usr/lib/jvm/java-6-sun/libJAVA_HOME=/usr/lib/jvm/java-6-sunnano /etc/jvm将该行添加到各项最上面：/usr/lib/jvm/java-6-sunupdate-java-alternatives -s java-6-sun
