Question

I have a dispatcher-servlet.xml and an applicationContext.xml.

I have been doing some refactoring, and moved

<mvc:annotation-driven/>
<context:component-scan base-package="com.xxx"/>

from dispatcher-servlet.xml to applicationContext.xml.

I now get this error:

2012-01-26 10:34:36.434:WARN::Nested in org.springframework.beans.factory.xml.XmlBeanDefinitionStoreException: Line 11 in XML document from ServletContext resource [/WEB-INF/applicationContext.xml] is invalid; nested exception is org.xml.sax.SAXParseException: cvc-complex-type.2.4.c: The matching wildcard is strict, but no declaration can be found for element 'context:component-scan'.:
org.xml.sax.SAXParseException: cvc-complex-type.2.4.c: The matching wildcard is strict, but no declaration can be found for element 'context:component-scan'.

My applicationContext.xml looks like this:

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

I have been doing some refactoring, and moved <mvc:annotation-driven/> from dispatcher-servlet.xml to applicationContext.xml.

You don’t want to do that. <mvc:annotation-driven/> is there to enable annotation-style MVC controllers, and those controllers must reside in dispatcher-servlet.xml. Putting <mvc:annotation-driven/> in applicationContext.xml is pointless, it will have no meaningful effect.

I should probably answer the question, though, amnd the answer is that while you’ve declared the mvc namespace, you did not tell Spring where to find the schema for it. Add

http://www.springframework.org/schema/mvc http://www.springframework.org/schema/mvc/spring-mvc.xsd

to the schemaLocation attribute in applicationContext.xml
