myeclipse有关问题

myeclipse问题？
单独启动TOMCAT没问题。。。可在myeclipse里启动就出现

严重:   Error   in   resourceStart()
2007-6-28   7:52:59   org.apache.catalina.core.StandardContext   start
严重:   Error   getConfigured
2007-6-28   7:52:59   org.apache.catalina.core.StandardContext   start
严重:   Context   startup   failed   due   to   previous   errors
2007-6-28   7:52:59   org.apache.catalina.core.StandardContext   start
严重:   Exception   during   cleanup   after   start   failed
LifecycleException:     Container   StandardContext[/olmail]   has   not   been   started

是怎么回事啊！！

你再检查一下你的工程的配置文件。
