Install Sun/Oracle JDK in Ubuntu 11.10

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)

1. 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。
2. 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
   

3. 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

   update-alternatives --quiet --install /usr/bin/jexec jexec /usr/lib/jvm/java-7-oracle/jre/lib/jexec 63
   

4. 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
   

   內容則如下

   name=java-7-oracle
   alias=java-7-oracle
   priority=63
   section=non-free

   plugin mozilla-javaplugin.so /usr/lib/jvm/java-7-oracle/jre/lib/amd64/libnpjp2.so
   

5. 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
