linux下配置java的运行环境

linux下配置java的运行环境
假如安装的路径在/usr/local/java/下，配置/etc/profile文件如下：
JAVA_HOME=/usr/local/java/j2sdk1.4.2_04
export JAVA_HOME
PATH=$PATH:$JAVA_HOME/bin
export PATH
CLASSPATH=.;/usr/local/java/j2sdk1.4.2_04/lib/dt.jar;/usr/local/java/j2sdk1.4.2_04/lib/tools.jar
export CLASSPATH

如果你想你的浏览器也支持java的小应用程序（applet），你就需要设置一个符号链接，假如你的浏览器是mozilla,路径是/usr/lib/mozilla-1.2.1, 而你的j2dk的安装目录为/usr/local/java/j2sdk1.4.2_04/

现在做如下的动作就可以了

#ln -s /usr/local/java/j2sdk1.4.2_04/jre/plugin/i386/ns610/libjavaplugin_oji.so /usr/lib/mozilla-1.2.1/plugins/

现在你再打开浏览器，输入about:plugins

你将看到如下的内容
