我已经将J2DK装好,并且J2DK目录为/usr/java/j2sdk1.4.2_08,环境变量已经添加我添加的环境变量是这样的:
# /etc/profile
export JAVA_HOME=/usr/java/j2sdk1.4.2_08
export CLASSPATH=$CLASSPATH:$JAVA_HOME/lib:$JAVA_HOME/jre/lib
export PATH=$JAVA_HOME/bin:$JAVA_HOME/jre/bin:$PATH:$HOMR/bin
# System wide environment and startup programs, for login setup
# Functions and aliases go in /etc/bashrc
pathmunge () {
if ! echo $PATH | /bin/egrep -q "(^|:)$1($|:)" ; then
if [ "$2" = "after" ] ; then
PATH=$PATH:$1
else
PATH=$1:$PATH
fi
fi
}
# Path manipulation
if [ `id -u` = 0 ]; then
pathmunge /sbin
pathmunge /usr/sbin
pathmunge /usr/local/sbin
fi
"/etc/profile" 51L, 1006C
请高手指点下....
# /etc/profile
export JAVA_HOME=/usr/java/j2sdk1.4.2_08
export CLASSPATH=$CLASSPATH:$JAVA_HOME/lib:$JAVA_HOME/jre/lib
export PATH=$JAVA_HOME/bin:$JAVA_HOME/jre/bin:$PATH:$HOMR/bin
# System wide environment and startup programs, for login setup
# Functions and aliases go in /etc/bashrc
pathmunge () {
if ! echo $PATH | /bin/egrep -q "(^|:)$1($|:)" ; then
if [ "$2" = "after" ] ; then
PATH=$PATH:$1
else
PATH=$1:$PATH
fi
fi
}
# Path manipulation
if [ `id -u` = 0 ]; then
pathmunge /sbin
pathmunge /usr/sbin
pathmunge /usr/local/sbin
fi
"/etc/profile" 51L, 1006C

运行一下命令行看看是否可以正确执行：
1)测试环境变量:
java -version
2)测试 JDK:
[root@www ~]# vi hello.java
public class hello {
public static void
main(String args [ ])
{ System.out.println("Hello World!");
System.out.println("看到这些代表安装成功啦!");
System.out.println("2005/9/5");
}
}
[root@www ~]# javac hello.java
[root@www ~]# java hello
Hello World!
看到这些代表安装成功啦!
