,tomcat报错

求助,tomcat报错
我编写的一个html,一个servlet。html是welcome.html,里面提供一个输入框,输入登陆者名字,提交之后调用servlet,得到输入的名字信息,并显示,欢迎XXX。程序很简单,没什么。问题是老是调不出来。我用myeclipse+tomcat可以正常运行,但是一旦我只用tomcat就无论如何调不出来,于是就有了下面这段报错信息。各位帮忙看看,到底是什么问题。

HTTP Status 500 -

------解决方案--------------------
<servlet-class>servlet.00.WelcomeServlet</servlet-class>
这种路径有问题没?
