为什么项目部署不上去
利用tomcat部署web项目，已经通过eclipse部署到tomcat的webapps目录下了，tomcat也启动了，能看到启动成功的页面，但访问部署的项目时报错如下：
type Status report
message /BPSbefore/
description The requested resource (/BPSbefore/) is not available.
tomcat启动时的信息如下：

不知道是什么原因？
[解决办法]
你在tomcat的management中看这个应用是正常状态
[解决办法]
你说的有问题：
首先，你的项目一定有问题，虽然tomcat启动了！
看这里：
严重: Skipped installing application listeners due to previous error(s)
2010-1-29 3:01:52 org.apache.catalina.core.StandardContext start
严重: Error listenerStart
这种情况很多原因有可能造成！譬如，你项目里的jar包有问题！其实，说白了，你的项目根本就没有启动成功！只是tomcat启动了！

我也经常碰到这种情况，看看配置文件是不是写错了，我遇到的大部分是配置文件写错了
