Answer 1

在/etc/profile文件中设置path, classpath和java_home, 最后再export :
比如我机器的设置是：JAVA_HOME=/opt/WebSphere/AppServer/java
PATH=/opt/WebSphere/AppServer/java/bin
CLASSPATH=$JAVA_HOME/jre/lib/rt.jar:$JAVA_HOME/jre/lib/i18n.jar:$JAVA_HOME/lib/dt.jar:$WTS_HOME/wts.jarexport JAVA_HOME PATH CLASSPATH结合你的情况来修改吧

Answer 4

加上：
JAVA_HOME=/usr/jdk1.4.0
PATH=$PATH:JAVA_HOME/bin
CLASSPATH=.:JAVA_HOME/lib/dt.jar:JAVA_HOME/lib/tools.jar .........
export CLASSPATH PATH
就行了
