[size=small]JDK版本 ： 1.6
JDK变量配置 ： classpath=C:\Java\jdk1.6.0\bin
JAVA_HOME=C:\Java\jdk1.6.0
Path=C:\Java\jdk1.6.0\bin

tomcat版本 ： 6.x
tomcat路径 ： F:\apache-tomcat-6.0.20[/size]

[color=olive]通过使用[/color]
[color=red] Runtime.getRuntime().exec("cmd /C start F:\apache-tomcat-6.0.20\bin\startup.bat")[/color]
命令调用tomcat 启动文件，无法成功
[color=red] error: The CATALINA_HOME environment variable is not defined correctly
This environment variable is needed to run this program[/color]
