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 Server
2、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。
