【求助】我的j2sdk安装和配置以后还是不行！！请帮帮我
我的系统是red hat es 3，kernel 2.4.21-9.EL-i686,装了j2sdk-1_4_0-fcs-linux-i386.rpm，根据一些帖子我吧/etc/profiel配置如下：
pathmunge () {
if ! echo $PATH | /bin/egrep -q "(^|:)$1($|:)" ; then
if [ "$2" = "after" ] ; then
PATH=$PATH:$1
else
PATH=$1:$PATH
fi
fi}
# Path manipulation
JAVA_HOME=/usr/java/j2sdk
CLASSPATH=/usr/java/j2sdk/lib/tools.jar:/usr/java/j2sdk/lib/dt.jar
PATH=$PATH:$HOME/bin:/usr/java/j2sdk/bin （以上3行是根据相关配置帖子写的）
if [ `id -u` = 0 ]; then
pathmunge /sbin
pathmunge /usr/sbin
pathmunge /usr/local/sbin
fi
pathmunge /usr/X11R6/bin after
unset pathmunge
# 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
export JAVA_HOME CLASSPATH
for i in /etc/profile.d/*.sh ; do
if [ -r "$i" ]; then
. $i
fi
done
unset i
配置完毕后
# source /etc/profile
运行另一个小的java语言
屏幕显示如下：
Error:failed /usr/java/j2sdk/jre/lib/i386/client/libjvm.so,because libstdc++-libc6.1-
1.so.2:connot open shared object file:No such file or directory
是这个j2sdk版本不适合我的系统还是我的配置哪里有问题呢?是不是系统少什么文件呢？
谢谢大家能给我指点一下^_^ check these files:
/lib/libc.so.6 (glibc)
/usr/lib/gcc-lib/i686-pc-linux-gnu/3.4.0(your gcc version)/libstdc++.so.5 (gcc's c++)
if they are missing, install them :) 我从网上找了一个libstdc++6-3.4.2-67517cl.i386.rpm，这个可以吗？
安装以后，在你上边指出的路径下还是没有那个文件，我该怎么做？ make sure there rpms are installed, some of them are for development, but they are useful when you install software from source ball :)
Following file names are from Fedora Core 2. Under Redhat, may be the same.
glibc-2.3.3-27.i686.rpm
glibc-common-2.3.3-27.i386.rpm
glibc-devel-2.3.3-27.i386.rpm
glibc-headers-2.3.3-27.i386.rpm
glibc-utils-2.3.3-27.i386.rpm
cpp-3.3.3-7.i386.rpm
gcc-3.3.3-7.i386.rpm
gcc-c++-3.3.3-7.i386.rpm
libgcc-3.3.3-7.i386.rpm
libstdc++-3.3.3-7.i386.rpm
libstdc++-devel-3.3.3-7.i386.rpm
From your error message, you must install this one "libstdc++-3.3.3-7.i386.rpm" or name like "libstdc++-(version).(arch).rpm".
Try these two:
[url]http://download.fedora.redhat.com/pub/fedora/linux/core/1/i386/os/Fedora/RPMS/libstdc++-3.3.2-1.i386.rpm[/url]
[url]http://download.fedora.redhat.com/pub/fedora/linux/core/1/i386/os/Fedora/RPMS/libstdc++-devel-3.3.2-1.i386.rpm[/url]
The path I listed in my message is under Gentoo Linux. If you can install software from source, only need two package, glibc and gcc :) thank you very much!!
无论是否成共都很感谢楼上的兄弟^_^ [root@localhost home]# java hello.class
Exception in thread "main" java.lang.NoClassDefFoundError: hello/class
我的错误信息:(
请高手指教. 我已经设好了路径之类的
PATH=/usr/kerberos/sbin:/usr/kerberos/bin:/usr/java/j2sdk1.4.2_05/bin:/usr/java/j2sdk1.4.2_05/jre/bin:/usr/local/sbin:/usr/local/bin:/sbin:/bin:/usr/sbin:/usr/bin:/usr/X11R6/bin:/root/bin:.:/opt/rtems-4.6/bin
CLASSPATH=/usr/java/j2sdk1.4.2_05/lib:/usr/java/j2sdk1.4.2_05/jre/lib:.
JAVA_HOME=/usr/java/j2sdk1.4.2_05 "java -cp . hello", no ".class", "-cp ." is to set CLASSPATH with current directory if hello.class is under it. :(
Please read some Java book or JDK document, this is too basic. [root@localhost home]# java hello.class
Exception in thread "main" java.lang.NoClassDefFoundError: hello/class
………………………………………………&&&&&&&&&&&&&&&&&&&&&&&&&&￥￥￥￥￥￥￥￥￥￥￥￥￥￥￥￥￥￥￥￥￥￥￥￥￥￥
hello.class？？？？？？？？
不是Hello.class吗？？？
java的类名第一个字母要大写的； 其余 同楼上 我看见的PATH是这样设置的：
注意： 大写和小写要区分,j2sdk1.4.2.03的安装路径是在用户的主文件夹下的和1.4.2_02以前的路径是不一样的
export PATH=/usr/java/j2sdk1.4.2_02/bin:$PATH
export NPX_PLGIN_PATH=/usr/java/j2sdk1.4.2_0/jre/plugin/i38
最后输入：java -version命令进行检验如果成功会看见JDK的版本号:w
