急！为什么web.xml文件中总有红叉叉？？

今天在Myeclipse6.0中建立了一个web工程，但在配置web.xml文件的时候出错了。错误提示：
cvc-complex-type.2.4.a: Invalid content was found starting with element 'display-name'. One of '{"http://java.sun.com/
xml/ns/javaee":servlet-class, "http://java.sun.com/xml/ns/javaee":jsp-file}' is expected.
web.xml文件内容如下：
<?xml version="1.0" encoding="UTF-8"?>
<web-app version="2.5"

在第15，26，31行的<display-name>地方有红叉
谢谢大家！！

Answer 1

display-name应该放到sevlet-name上面的

Answer 2

我也碰到了，display-name只要放到sevlet-name 的上面就不会报错了

Answer 3

这个跟ide 有关系.一般不影响程序开发的.
还有可能是项目编码的问题. 编码不统一也会出这情况.

Answer 4

文件本身没有问题
可能是IDE自己的问题，可以忽略
