Tomcat启动时一闪而过，但是jdk环境变量配置正确，并使用java或者javac命令多可以运行，但是tomcat不能运行解决办法。

今天在使用tomcat6.0.7时出现Tomcat启动时一闪而过，但是jdk环境变量配置正确，并使用java或者javac命令多可以运行，但是tomcat不能运行解决办法。

1.在命令行中直接启动tomcat时查看错误信息 如;

C:\Users\Administrator>

C:\Users\Administrator>cd D:\apache-tomcat-6.0.37\bin

C:\Users\Administrator>d:

D:\apache-tomcat-6.0.37\bin>startup.bat

The JAVA_HOME environment variable is not defined correctly

This environment variable is needed to run this program

NB: JAVA_HOME should point to a JDK not a JRE

D:\apache-tomcat-6.0.37\bin>

D:\apache-tomcat-6.0.37\bin>

2.根据以上信息，配置java_home路径：如java_home="D:\Program Files\java\jdk1.6.0_21\bin"

配置jre路径： jre_home="D:\Program Files\java\jdk1.6.0_21\jre"

3.重新启动tomcat。

4.如果以上配置完成还是不能启动，请看下面配置.

5.由于tomcat的startup.bat启动时，调用的是catalina.bat ,而catalina.bat调用了setclasspath.bat

在setclasspath.bat中配置的就是tomcat运行时所需的jar包及使用所需的类。

在setclasspath.bat的头部配置JAVA_HOME和JRE_HOME的值。如下：

set JAVA_HOME=D:\Program Files\java\jdk1.6.0_21

set JRE_HOME=D:\Program Files\java\jdk1.6.0_21\jre

6.配置完成再次启动tomcat即可。

setclasspath.bat文件如下：

@echo off
