如果给坛主带来不便,先sorry

我已经设置好环境变量可还是提示如下

[root@localhost ~]# javac HelloWorld.java
libgcj-javac-placeholder.sh

This script is a placeholder for the /usr/bin/javac
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.

你安装的j2sdk吧，安装在哪个目录？环境变量如何设置的，贴出来大家学习学习 。

安装在/usr/java/j2sdk1.5.0_01
在/etc/profile文件中添加以下内容
JAVA_HOME=/usr/java/j2sdk1.5.0_01
PATH=$PATH:.:$JAVA_HOME/bin
CLASSPATH=$JAVA_HOME/lib/tools.jar:.:$JAVA_HOME/lib/dt.jar
export JAVA_HOME
export PATH
export CLASSPATH

可还是有问题啊...不知道怎么解决以上问题
