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

用eclipse做jsp文件，自动创立的文件表头出现这个报错，应该怎么处理？tomcat的插件已经安装上了。

有一处刚发现了，是中英文标点问题，这两处，一个是The word ‘username‘ is not correctly spelled，还一个是The document body. Contains all the content for the page.

JSP页面顶端出现“红色”的报错信息：The superclass "javax.servlet.http.HttpServlet" was not found on the Java Build Path。原来Javaweb工程类中没有添加Tomcat运行时相关类导致。下面是具体的解决方法：1、右击web工程-》属性或Build Path-》Java Build Path->Libraries-> Add Libray...->Server Runtime -》Tomcat Server2、切换到Java Build Path界面中的Orader and Export，选择Tomcat。

注意：按以上方法操作时，若打开Server Runtime后一片空白，需要设置Apache服务器。设置方法为：window->Preferences->Server->Runtime Environment -> add --> 选择Apache的版本后点Next，再填入你apache服务器软件的安装（解压后）地址。
