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
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 .
将会出现字幕，持续按回车键，直至屏幕显示要求输入yes/no，此时输入y回车，将会把jdk解压到文件夹，得到jdk1.6.0_12目录。
此时，jdk已安装完毕，下面进行配置
执行
代码:
sudo vi /etc/profile
在profile中修改，出现如下部分
引用:
# Set JAVA (这里是注释 不是SHELL命令)
JAVA_HOME=/home/administrator/下载/jdk1.5.0_22
JRE_HOME=/home/administrator/下载/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
执行
代码:
sudo source /etc/profile
此时，环境变量设置成功（设置环境变量的方法很多，不一一列举）
由于ubuntu中可能会有默认的jdk，如openjdk，所以，为了使默认使用的是我们安装的jdk，还要进行如下工作。
执行
代码:
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
通过这一步将我们安装的jdk加入java选单。
然后执行
代码:
update-alternatives --config java
通过这一步选择系统默认的jdk
这样，再在shell中输入
代码:
java -version
时，就会显示系统使用的java是sun的java。
