Tomcat5.0.28 + JDK1.5 + Eclipse3.1数据库连接池问题
其实不想麻烦大家的，但是小弟在网上看了很多例子，还是没有搭建成功，请大家指点一下：

结果在登录：http://127.0.0.1:8888/jado/ 显示如下界面！郁闷

麻烦大家指点我一下，哪里错了，或者配置的有问题，谢谢！
[解决办法]
http://127.0.0.1:8888/jado/index.jsp你先这样访问试试吧
[解决办法]
docBase= "D:\Workspace\jado\WebRoot\classes "
错了，改为工程目录
能明白 <Context crossContext= "true " displayName= "jado " docBase= "D:\Workspace\jado\WebRoot\classes " path= "/jado " reloadable= "true " workDir= "work\Catalina\localhost\jado "> 什么意思不？
