在Oracle買下Sun之後，Ubuntu上要安裝sun/oracle的JDK是愈來愈不容易...
還是做個筆記囉
安裝Sun JDK6
sudo add-apt-repository ppa:flexiondotorg/java sudo apt-get update sudo apt-get install sun-java6-jdk sun-java6-plugin sun-java6-fonts
安裝Oracle JDK7
這部份主要是參考Intalling Java 7 on Ubuntu Natty (11.04)
- 請至Oracle http://www.oracle.com/technetwork/java/javase/downloads/index.html Download最新的檔案，要注意配合作業系統。下列的例子以x64為主。
- 解壓縮後移到/usr/lib/jvm裡，並重新命名為java-7-oracle-1.7.0_02，再修改owner為root，最後建一個名為java-7-oracle的link，這樣以後若有新的版本，就只要修改link即可。
tar -xzf jdk-7u2-linux-x64.tar.gz sudo mv jdk1.7.0_02 /usr/lib/jvm/java-7-oracle-1.7.0_02 cd /usr/lib/jvm sudo chown -R root:root java-7-oracle-1.7.0_02 sudo ln -s java-7-oracle-1.7.0_02 java-7-oracle
- 以root的身份執行下列的指令，若不想一直下sudo，就先執行sudo -sH來切換身份吧

- 在/usr/lib/jvm建一份.java-7-oracle.jinfo的清單，請注意這是個隱藏檔，所以檔名是有個'.'
sudo vim /usr/lib/jvm/.java-7-oracle.jinfo

- update java alternatives
這時準備工作就完成了，可以開始設定ubuntu預設使用的jdk了
先執行下列指令
sudo update-alternatives --config java
正常的話可以看到下列的提示There are 2 choices for the alternative java (providing /usr/bin/java). Selection Path Priority Status ------------------------------------------------------------ * 0 /usr/lib/jvm/java-6-sun/jre/bin/java 63 auto mode 1 /usr/lib/jvm/java-6-sun/jre/bin/java 63 manual mode 2 /usr/lib/jvm/java-7-oracle/jre/bin/java 63 manual mode
此刻再輸入號碼2，選擇jdk7做為預設的java版本
當然也可以直接執行下列指令來改改sudo update-java-alternatives --set java-7-oracle
