eclipse中 报出The type javax.servlet.http.HttpServlet cannot be resolved. It is indirect错误

在Myeclispe部署项目后 报错

The type javax.servlet.http.HttpServlet cannot be resolved. It is indirect错误

如果在MyEclipse中遇到这种情况，也就是HttpServletRequest报红叉的时候，这样做
1、右键工程找到build path项
2、找到Add Libraries
3、点击myEclipse Libraries，Next
4、添加JavaEE 5
OK
