JAVA_HOME should point to a JDK not a JRE的一个解决办法

环境：win7

tomcata7.0解压版本

执行:service.bat install

报错：JAVA_HOME should point to a JDK not a JRE

网上找了几种解决方案，其中一种是成功的：

在setclasspath.bat的头部定义了JAVA_HOME和JRE_HOME的值，那么在这里手动设置JAVA_HOME变量

rem ---------------------------------------------------------------------------

rem Set CLASSPATH and Java options

rem

rem $Id: setclasspath.bat 505241 2007-02-09 10:22:58Z jfclere $

set JAVA_HOME=C:\Program Files\Java\jdk1.5.0_05

set JRE_HOME=C:\Program Files\Java\jre1.5.0_05

rem Make sure prerequisite environment variables are set

if not "%JAVA_HOME%" == "" goto gotJdkHome

if not "%JRE_HOME%" == "" goto gotJreHome

echo Neither the JAVA_HOME nor the JRE_HOME environment variable is defined

echo At least one of these environment variable is needed to run this program

goto exit
