又是JAVA的问题，很言重

superfang

这次我是栽倒这个问题上了，
        我安装了j2sdk1.4.2_05的包，可是在设计路径是出了问题：
        我在/etc/profile 加了这两句：CLASSPATH=.:JAVA-PATH/jre/lib/rt.jar
                                  PATH=JAVA-PATH/bin
         结果我的恶梦来了：基本上算是系统废了，
       这时怎么回事呢

sagaeon

你把别的PATH盖了    。这样吧： PATH = $PATH:JAVA-PATH/bin

superfang

我事后也发现这个问题了，不过已经晚了，系统已然重装了，还是谢谢你的指教

lapackapi

就改了个PATH就要重装系统? 楼主太脆弱了.

呵呵，这个问题好像很多人都遭过！

这是我的/etc/profile里java的路径设置:
export JAVA_HOME=/usr/share/jre
export CLASSPATH=$CLASSPATH:.
export PATH=$PATH:/usr/share/jre/bin

这是我运行java 后的问题,

libgcj-java-placeholder.sh

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.

情多多的指教,我用的FC3的系统

microdict

你的路径还是没设对吧？你的jdk装到那里了？现在用的是系统自带的.

superfang

我装在/usr/java/j2sdk.1.4.2_06
我用的是FC3啊，而且我也更改了路径社这，改道了上面的路径里，可还是不行啊，

microdict

JAVA_HOME=/usr/java/j2sdk.1.4.2_06

export .:$JAVA_HOME/bin:$PATH

superfang

提示这样的:
libgcj-java-placeholder.sh

你当前的路径是多少？我看你的信息应该是/usr/bin/java,这个是系统自带的jvm的位置，命令执行会先在当前目录查找，之后再会到$PATH中查找，所以你的总是这个信息。
你用绝对路径试一下：
/usr/java/j2sdk.1.4.2_0/bin/java
