问题：使用免安装的tomcat双击startup.bat后，启动窗口一闪而过，而且tomcat服务未启动。

原因：在启动tomcat是需要读取环境变量和配置信息，缺少了这些信息，就不能登记环境变量，导致了tomcat的闪退。

解决办法：

1.在已解压的tomcat的bin文件夹下找到startup.bat，右击->编辑。在文件头加入下面两行：

SET JAVA_HOME=D:\Java\jdk1.6.0_10 （java jdk目录）
SET TOMCAT_HOME=E:\tomcat-6.0.35 （解压后的tomcat文件目录）

2.同样的。在已解压的tomcat的bin文件夹下找到shutdown.bat，右击->编辑。在文件头加入下面两行：

SET JAVA_HOME=D:\Java\jdk1.6.0_10 （java jdk目录）
SET TOMCAT_HOME=E:\tomcat-6.0.35 （解压后的tomcat文件目录）

@echo off  
SET JAVA_HOME=C:\Program Files (x86)\Java\jdk1.7.0_11  
SET TOMCAT_HOME=D:\apache-tomcat-6.0.30
