linux下java的运行环境怎么配置?

moshen168888

我使用redhat linux
jdk路径:/usr/java/j2sdk1.4.2_08
/etc/profile 是这样配置的
# /etc/profile

# 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

pathmunge /usr/X11R6/bin after


# No core files by default
ulimit -S -c 0 > /dev/null 2>&1

USER="`id -un`"
LOGNAME=$USER
MAIL="/var/spool/mail/$USER"

HOSTNAME=`/bin/hostname`
HISTSIZE=1000

if [ -z "$INPUTRC" -a ! -f "$HOME/.inputrc" ]; then
    INPUTRC=/etc/inputrc
fi

export PATH USER LOGNAME MAIL HOSTNAME HISTSIZE INPUTRC

for i in /etc/profile.d/*.sh ; do
    if [ -r "$i" ]; then
            . $i
    fi
done



unset i
unset pathmunge

# java
JAVA_HOME=/usr/java/j2sdk1.4.2_08

export JAVA_HOME

CLASSPATH=.:/usr/java/j2sdk1.4.2_08/lib:/usr/java/j2sdk1.4.2_08/jre/lib

export CLASSPATH

PATH=$PATH:$JAVA_HOME/bin:$JAVA_HOME/jre/bin

export PATH

我在终端中输入java,出这样提示:
This script is a placeholder for the /usr/bin/java
master link required by jpackage.org conventions.  libgcj's
rmiregistry, rmic and jar tools are now slave symlinks to these
masters, and are managed by the alternatives( system.

This change was necessary because the rmiregistry, rmic and jar tools
installed by previous versions of libgcj conflicted with symlinks
installed by jpackage.org JVM packages.
Usage: gij [OPTION] ... CLASS [ARGS] ...
          to invoke CLASS.main, or
       gij -jar [OPTION] ... JARFILE [ARGS] ...
          to execute a jar file
Try `gij --help' for more information.

请高人指教,谢谢
