Question

Currently Running

Tomcat: v6

Spring Tools Suite: v2.7.2

Spring Framework: spring-webmvc-3.0.5

Servlet XML

 <?xml version="1.0" encoding="UTF-8"?>
 <beans xmlns="http://www.springframework.org/schema/beans"
        xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
        xmlns:mvc="http://www.springframework.org/schema/mvc"
        xmlns:context="http://www.springframework.org/schema/context"
        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/spring-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">

      <mvc:annotation-driven />

      <mvc:resources mapping="/resources/**" location="/resources" />

      <context:component-scan base-package="com.app.mvc" />

 </beans>

web.xml partial code

<servlet-mapping>
    <servlet-name>duckapp</servlet-name>
    <url-pattern>/</url-pattern>
</servlet-mapping>

Servlet Purpose

web.xml maps all urls to the servlet with the exception of mvc:resources mapping static files.

Bugs

• cvc-complex-type.2.4.c: The matching wildcard is strict, but no declaration can be found for element ‘mvc:annotation-driven’. app-servlet.xml /app/www/WEB-INF

• cvc-complex-type.2.4.c: The matching wildcard is strict, but no declaration can be found for element ‘mvc:resources’. app-servlet.xml /app/www/WEB-INF

Known Issues

• http://www.springframework.org/schema/mvc/spring-mvc-3.0.xsd doesn’t contain the element resource

• If replaced by http://www.springframework.org/schema/mvc/spring-mvc-3.1.xsd still doesn’t work and may not be working according to jar files of spring 3.05

• mvc:resources appeared in spring v3.0.4, but has no new xsd

Question

How can I fix the compile errors to get mvc:resources working correctly?

I’ve been digging around 2 hours for this, no solid answer yet…

Answer 1

In your spring context xml mvc namespace url should match url in schemaLocation. Something like this:

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
       xmlns:mvc="http://www.springframework.org/schema/mvc"
       xsi:schemaLocation="
         http://www.springframework.org/schema/mvc
         http://www.springframework.org/schema/mvc/spring-mvc-3.0.xsd">

This is a standard XML namespace declaration. The namespace url is sort of an unique id, which is then mapped to the actual schema location in xsi:schemaLocation.
