谢谢，高手，如果网页显示不出来，java.net.BindException: Address already in use: JVM_Bind:8081 可能是其它的程序已经占用了8081端口,查检一下, 去Tomcat的config目录下面。有一个server.xml文件，打开文件找到 <Connector port="8081" 修改一下端口号应该就没问题了。

什么是Tomcat的bin目录呀，我装了tomcat6.0 后，在开始运行中输入cmd后进入了c：\windows\system32\cmd.exe,这是不是呀,可为什么我输入startup后说startup不是内部或外部命令，也不是内部或外部文件

我的数据库连接出现如下错误，各位看看怎么回事

太谢谢你了！
我的tomcat问题困扰我好几天了
气得我都想摔机子了
还好你给解决了‘
非常感谢！！

不错,顶

他的教程上就没怎么提JDK和TOMCAT的环境变量配置，所以会出现问题的。

安装JDK1.6.0 _07和Tomcat 6.0后已经设置过环境变量，在网址栏上打127.0.0.1:8080后显示Internet Explorer 无法显示该网页，请教一下问题出在那了？该如何解决呀？

在网址栏上打127.0.0.1:8080能显示TOMCAT主页,而且打开一个自己编的index.jsp能打开,请指教

检查tomcat设置

你好,我的数据库老是出现

这样的问题,我是刚学的,想配置好,演试一下学习程序,嘿,一开始就遇上这挫节了,请各位教师多多指教

@chao@444
我是XP系统，装了个sql server 2005 express 还有mysql。你出现了什么问题，可否描述一下

请问你用的是什么版本的windows系统呀,配什么的数据库,
我是server2003的.配SQL2000sp4的数据库老出现问题,可否提供下配置给我这个菜鸟参考一下

请问一下,JDK1.6的环境变量不用设置path和classpath等路径吗??
