  项目中某一.jps页面忽然出现错误,鼠标点上去为:The superclass "javax.servlet.http.HttpServlet" was not found on the Java Build Path.

2.解决:

2.1.在Eclipse中,Window-->preference --> servers --> runtime --> environments --> 全部删除

2.2.Add-->Browse-->选择本地tomcat文件夹所在位置-->确定 --> finish-->OK

ps: Select the type of runtime environment 这一步请选择本机装Tomcat的对应版本
