myeclipse2014 The superclass "javax.servlet.http.HttpServlet" was not found on the Java Build Path

导入一个项目所有jsp文件提示 The superclass “javax.servlet.http.HttpServlet” was not found on the Java Build Path,百度查了一圈是说Tomcat没有配置好的缘故,查了下发现自己的myeclipse里并没有Server Runtime的选项,谨慎起见细细查了下功能发现其实可以解决,步骤如下:
1、右键项目点击如图选项
myeclipse2014 The superclass "javax.servlet.http.HttpServlet" was not found on the Java Build Path2、第二步
myeclipse2014 The superclass "javax.servlet.http.HttpServlet" was not found on the Java Build Path3、第三步
myeclipse2014 The superclass "javax.servlet.http.HttpServlet" was not found on the Java Build Path

最后就是选中你要添加的tomact版本了,不要用myeclipse自带的,配置完之后如果红叉子若还在不用紧张,重新保存下红叉就没了
