Resource and properties file management issue

I am trying to learn spring. I have some trouble to manage my resource and properties file.

This is my mvc-dispatcher-servlet.xml file.

<beans xmlns="http://ift.tt/GArMu6"
    xmlns:context="http://ift.tt/GArMu7"
    xmlns:xsi="http://ift.tt/ra1lAU" xmlns:mvc="http://ift.tt/1bHqwjR"
    xsi:schemaLocation="
        http://ift.tt/GArMu6     
        http://ift.tt/1cnl1uo
         http://ift.tt/1bHqwjR
        http://ift.tt/1kF4x7W
        http://ift.tt/GArMu7 
        http://ift.tt/1ldEMZY">

    <context:component-scan base-package="com.test.common.controller" />

    <bean
        class="org.springframework.web.servlet.view.InternalResourceViewResolver">
        <property name="prefix">
            <value>/WEB-INF/pages/</value>
        </property>
        <property name="suffix">
            <value>.jsp</value>
        </property>
    </bean>

    <bean id="messageSource"
        class="org.springframework.context.support.ReloadableResourceBundleMessageSource">
        <property name="basename" value="messages/messages">
        </property>
    </bean>

    <bean id="localeChangeInterceptor"
        class="org.springframework.web.servlet.i18n.LocaleChangeInterceptor">
        <property name="paramName" value="lang">
        </property>
    </bean>

    <bean id="localeResolver"
        class="org.springframework.web.servlet.i18n.CookieLocaleResolver">
        <property name="defaultLocale" value="tr">
        </property>
    </bean>

    <bean id="handlerMapping"
        class="org.springframework.web.servlet.mvc.annotation.DefaultAnnotationHandlerMapping">
        <property name="interceptors">
            <ref bean="localeChangeInterceptor"/>
        </property>
    </bean>

    <mvc:resources mapping="/resources/**" location="/resources/" />
    <mvc:annotation-driven />
</beans>

And this is my file descriptor.

My problem is:

When I delete

<mvc:resources mapping="/resources/**" location="/resources/" />
    <mvc:annotation-driven />

from mvc-dispatcher-servlet.xml file header.css file caanot be loaded.

When I don't delete I am not be able to change the language. What should I do to solve this problem.

Thanks.
