I am facing difficulty in configuring static resources (such as js, css, images) in spring security 3. Here is my configuration file:

<beans xmlns="http://www.springframework.org/schema/beans"
    xmlns:security="http://www.springframework.org/schema/security"
    xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
    xsi:schemaLocation="http://www.springframework.org/schema/beans 
              http://www.springframework.org/schema/beans/spring-beans-3.1.xsd
              http://www.springframework.org/schema/security 
              http://www.springframework.org/schema/security/spring-security-3.1.xsd">



    <bean id="authenticationEntryPoint"
        class="org.springframework.security.web.authentication.LoginUrlAuthenticationEntryPoint">
        <property name="loginFormUrl" value="/login.htm" />
    </bean>

    <security:http security="none" pattern="/js/ajaxScript.js"/>   
    <security:http security="none" pattern="/js/commonScript.js"/>  

    <bean class="org.springframework.security.web.access.expression.DefaultWebSecurityExpressionHandler" />

    <security:http auto-config="false" entry-point-ref="authenticationEntryPoint" disable-url-rewriting="true" use-expressions="true">

        <security:custom-filter position="FORM_LOGIN_FILTER"
            ref="customAuthenticationProcessingFilter" />

<!--        <security:intercept-url pattern="/js/jquery.min.js" access="isAuthenticated()" /> -->
<!--        <security:intercept-url pattern="/js/**/**" access="permitAll" />  -->
        <security:intercept-url pattern="/displayAdminPage.htm" access="hasRole('ROLE_ADMIN')" />
        <security:access-denied-handler ref="accessDeniedHandler" />

    </security:http>

    <security:authentication-manager alias="authenticationManager">
       <security:authentication-provider user-service-ref="customUserDetailService">
       </security:authentication-provider>
    </security:authentication-manager> 

    <bean id="customUserDetailService" class="com.qait.cdl.services.impl.UserSecurityServiceImpl">
        <property name="userDao" ref="userDao"/>
       </bean>

    <bean id="customAuthenticationProcessingFilter"
        class="com.qait.cdl.services.impl.CustomAuthenticationProcessingFilter">
        <property name="authenticationManager" ref="authenticationManager" />
    </bean>

    <bean id="accessDeniedHandler"
        class="org.springframework.security.web.access.AccessDeniedHandlerImpl">
        <property name="errorPage" value="/WEB-INF/jsp/customLoginForm/denied.jsp" />
    </bean>
</beans> 

I'm unsure where the issue lies. I need all js, images, and css files to be exempt from spring security. The JS files are located in the webapp/js and webapp/js/commonScript folders, while the images are in the webapp/images folder.

Below is my web.xml configuration:
