Neither the JAVA_HOME nor the JRE_HOME environment variable is defined
At least one of these environment variable is needed to run this program

原因：找不到jdk或者jre路径。

解决办法：在setclasspath.bat的开头声明环境变量，打开tomcat的bin目录下面的setclasspath.sh，添加红色部分，路径修改为自己机器jdk和jre路径即可。

#!/bin/sh

*************************************************加上下面的配置信息

 

export JAVA_HOME=/opt/zimbra/jdk1.6.0_31
export JRE_HOME=/opt/zimbra/jdk1.6.0_31/jre

这个根据你系统jdk的实际的安装路径配置
