The superclass "javax.servlet.http.HttpServlet" was not found on the Java Build

eclipse好久之前做的java项目，今天打开发现许多jsp页面有如下错误：
The superclass "javax.servlet.http.HttpServlet" was not found on the Java Build Path

如果没有添加Tomcat Server ，需手动添加一下（不过我已经添加过了）
project->Java Build Path->Libraries-> Add Libray->Server Runtime ->Tomcat Server
继续查找原因
Windows->Preferences->Server->Runtime Environments->add->Apache Tomcat v7.0->next 找到相应tomcat7.0的安装路径（这个我也添加过了）
不过在点击我已配置过的Tomcat Server，发现了下面信息：
The specified Tomcat installation directory does not exist.

指定Tomcat的安装目录不存在
原来是换了电脑后，重新放置了Tomcat的安装位置，重新Edit下
还是不行？
把项目从eclipse里面删掉

在把刚从eclipse里刚删的项目import回来

完美解决！
