<servlet>

<servlet-class>com.hjc.Bailang</servlet-class>

<servlet-name>langlang</servlet-name>

 

</servlet>

这段报错，报错为：

cvc-complex-type.2.4.a: Invalid content was found starting 

 with element 'servlet-class'. One of '{"http://java.sun.com/xml/

 ns/javaee":description, "http://java.sun.com/xml/ns/

 javaee":display-name, "http://java.sun.com/xml/ns/

 javaee":icon, "http://java.sun.com/xml/ns/javaee":servlet-

 name}' is expected.

 

解决办法：

出现原因：位置颠倒

<servlet>

<servlet-name>langlang</servlet-name>

<servlet-class>com.hjc.Bailang</servlet-class>

</servlet>
