Error in Context xml file - cvc-complex-type.2.4.c:

[nitinram agarwal]

Hello,
I am new to Spring and am trying to get a simple tutorial using JSP page running.

I am getting the following error in one of the context file I am using (under webContent->Web-INF folder). Following is the error message

"cvc-complex-type.2.4.c: The matching wildcard is string:but no declaration can be found for the element mvc:annotation-driven"


Here is the XML file

<?xml version="1.0" encoding="UTF-8"?>

<beans xmlns="http://www.springframework.org/schema/beans"
   xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

Because you didn't fully bring in the mvc namespace. And you have aop namespace partly in there too. xml namespaces are about xml, and Spring creates a number of xml namespaces. You need two parts in the header to add a namespace.

The first part like this

xmlns:mvc="http://www.springframework.org/schema/mvc"

sets the prefix "mvc" to the key string of "http://www.springframework.org/schema/mvc"

That key is used in the xsi:schemaLocation attribute, where you need the key and the .xsd, like a key value pair.

If you look at your schemaLocation you can see each pair. You have one for beans tags
http://www.springframework.org/schema/beans
http://www.springframework.org/schema/beans/spring-beans-3.0.xsd

You have one for context, and one for aop.

To fix it, you can just change the schemaLocation parts in the string that points to aops xsd file and where ever you see the text "aop" replace it with "mvc"

So you end up having

xsi:schemaLocation="http://www.springframework.org/schema/beans  
           http://www.springframework.org/schema/beans/spring-beans-3.0.xsd  
           http://www.springframework.org/schema/mvc  
           http://www.springframework.org/schema/mvc/spring-mvc-3.0.xsd  
           http://www.springframework.org/schema/context  
           http://www.springframework.org/schema/context/spring-context-3.0.xsd">
