cvc-complex-type.2.3: Element 'web-app' cannot have character [children], because the type's content

web.xml文件添加ssl访问限制后出现错误:

cvc-complex-type.2.3: Element ‘web-app’ cannot have character [children], because the type’s content type is element-only

<web-app version=”2.5” xmlns=”http://java.sun.com/xml/ns/javaee”

xmlns:xsi=”http://www.w3.org/2001/XMLSchema-instance”

xsi:schemaLocation=”http://java.sun.com/xml/ns/javaee

http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd”>

出错原因为xml头文件中第三行：

xmlns=”http://java.sun.com/xml/ns/javaee”

改成j2ee后解决问题。
