如何使java的环境变量设置生效阿？

halcyon79

OS: Debian unstable

装了j2sdk
放到了/usr/local/j2sdk1.4.2_01

然后修改了/etc/profile

内容如下
# /etc/profile: system-wide .profile file for the Bourne shell (sh(1))
# and Bourne compatible shells (bash(1), ksh(1), ash(1), ...).

PATH="/usr/local/bin:/usr/bin:/bin:/usr/bin/X11:/usr/games"

if [ "$PS1" ]; then
  if [ "$BASH" ]; then
    PS1='\u@\h:\w\$ '
  else
    if [ "`id -u`" -eq 0 ]; then
      PS1='# '
    else
      PS1='$ '
    fi
  fi
fi

export PATH

umask 022
PATH=$PATH:/usr/lib/oss/bin # ADDED_BY_OSS
export PATH # ADDED_BY_OSS

#J2SDK Setting
JAVA_HOME=/usr/local/j2sdk1.4.2_01
PATH=$PATHJAVA_HOME/bin
export JAVA_HOME PATH

而PATH路径里没有java的东西

所以执行不了lumaqq
