七． Sco unix 下服务自启动与停止配置
自启动编辑文件/etc/rc2.d/S99WEBSERV(文件名自定义)
JAVA_HOM=/usr/java
CATALINA_HOME=/usr/lib/apache/tomcat
/usr/lib/apache/bin/apachectl start
/usr/lib/apache/tomcat/bin/startup.sh
echo "apache tomcat has been started !"
自停止编辑文件/etc/rc0.d/P99WEBSERV(文件名自定义)
JAVA_HOMa=/usr/java
CATALINA_HOME=/usr/lib/apache/tomcat
/usr/lib/apache/bin/apachectl stop
/usr/lib/apache/tomcat/bin/shutdown.sh
echo "apache tomcat has been stoped !"
............................
我的自启动为
/etc/rc2.d/S98tomcat
JAVA_HOM=/usr/java
CATALINA_HOME=/usr/apach-tomcat-4.1.36
/usr/apach-tomcat-4.1.36/bin/startup.sh
echo "apache tomcat has been started !"
自停止编辑文件为
/etc/rc0.d/P98tomcat
JAVA_HOMa=/usr/java
CATALINA_HOME=/usr/apach-tomcat-4.1.36
/usr/apach-tomcat-4.1.36/bin/shutdown.sh
echo "apache tomcat has been stoped !"

可是在系统启动的提示 $JAVA_HOME NOT DEFINED
完了TOMCAT根本就没有启动
是什么原因啊?
我在  /.PROFILE
$JAVA_HOME=/usr/java2
