Now my os is Ubuntu10.4.And there are lots of problem with me and Ubuntu.
How can i set chinese input ?
I can see PinYin Input,but it does not work.....
It is not the main proble about today .Writing in english will give me some chance.
1:Down Load JDK 5,The lastest is JDK 6, you can get from system/Systmemanger/PackageManger.But there is no JDK5 Resource.
So you need to download it from the sun. I can confirm that there is it in www.sun.com.
what i got is : jdk-1_5_0_22-linux-i586.bin
Do you have got what you need ?
2:Put jdk-1_5_0_22-linux-i586.bin file to my /home/administrator/java directory.
3:in Command Line Interface ,you need get in the file directory /home/administrator/java
sudo chmod u+x jdk-1_5_0_22-linux-i586.bin
./jdk-1_5_0_22-linux-i586.bin
then you see some readme about sun .......
more and more .
將會出現字幕，持續按回車鍵，直至屏幕顯示要求輸入yes/no，此時輸入y回車，將會把jdk解壓到文件夾，得到jdk1.6.0_12目錄。
此時，jdk已安裝完畢，下面進行配置
執行
代碼:
sudo vi /etc/profile
在profile中修改，出現如下部分
引用:
# Set JAVA (這裡是注釋 不是SHELL命令)
JAVA_HOME=/home/administrator/下載/jdk1.5.0_22
JRE_HOME=/home/administrator/下載/jdk1.5.0_22/jre
PATH=$JAVA_HOME/bin:$JAVA_HOME/jre/bin:$PATH
CLASSPATH=.:$CLASSPATH:$JAVA_HOME/lib:$JAVA_HOME/jre/lib
export JAVA_HOME JRE_HOME PATH CLASSPATH
export PATH
執行
代碼:
sudo source /etc/profile
此時，環境變量設置成功（設置環境變量的方法很多，不一一列舉）
由於ubuntu中可能會有默認的jdk，如openjdk，所以，為了使默認使用的是我們安裝的jdk，還要進行如下工作。
執行
代碼:
update-alternatives --install /usr/bin/java java /usr/lib/jvm/java/jdk1.6.0_12/bin/java 300
update-alternatives --install /usr/bin/javac javac /usr/lib/jvm/java/jdk1.6.0_12/bin/javac 300
通過這一步將我們安裝的jdk加入java選單。
然後執行
代碼:
update-alternatives --config java
通過這一步選擇系統默認的jdk
這樣，再在shell中輸入
代碼:
java -version
時，就會顯示系統使用的java是sun的java。
