#java
JAVA_HOME=/opt/j2sdk_nb/j2sdk1.4.2
JRE=/opt/j2sdk_nb/j2sdk1.4.2/bin
CLASSPATH=$JAVA_HOME/lib:$JRE/lib:.
PATH=$PATH:$JAVA_HOME/bin:$JRE/bin:.
export JAVA_HOME JRE CLASSPATH PATH

上面这个到底错在什么地方？ java -version还是1.3而不是我装的1.4.2

JAVA_HOME=/usr/java/j2sdk1.4.2_01
export JAVA_HOME
CLASSPATH=.:/usr/java/j2sdk1.4.2_01/lib:/usr/java/j2sdk1.4.2_01/jre/lib
export CLASSPATH
PATH=.:$PATH:$JAVA_HOME/bin:$JAVA_HOME/jre/bin
export PATH
JRE=/usr/java/j2sdk1.4.2_01/jre
export JRE

我只加了这么几句;

PATH=$PATH:/usr/java/j2sdk1.4.2_01/bin
CLASSPATH="./:/usr/java/j2sdk1.4.2_01/lib/tools.jar:/usr/java/j2sdk1.4.2_01/jre/lib/rt.jar"
