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 rem Licensed to the Apache Software Foundation (ASF) under one or more rem contributor license agreements.
