Direct-click Startup.bat under Windows to start Tomcat service

On the XP has already installed the JDK1.5 and set up the Java_home, but the Tomcat is not found in the boot process.

The error message is as follows: Neither the Java_home nor the JRE_HOME environment variable is defined at least one of these environment variable I s needed to run this program; java_home jre_home path is not found, what solution?

The reason is not known, the following to see the solution:

1, Analysis Startup.bat startup script: found that it called Catalina.bat, and Catalina.bat called Setclasspath.bat

2, the Java_home and jre_home values are defined in the head of the Setclasspath.bat, then manually set the Java_home variable here

TOMCAT5 need jdk1.6 do support, jdk1.5 not enough.
