Spring MVC CSS and JS not loading

Including floder structure

I am developing a web application in Spring MVC. I have issues loading CSS and JS files in JSP.

I googled for hours and tried all options, but not succeeded. Here is what i did

1. tried to load as normal web app giving relative path
2. tried including mvc:resources
3. tried loading through Resource Servlet even then nothing worked.

All three were tried separately I am wondering what had i missed.

traditional link for #1

<link rel="stylesheet" type="text/css" href="css/bootstrap.min.css">

No changes done in mvc-config or web.xml

App Config for #2

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

Web XML for #3

<servlet>
    <servlet-name>Resource Servlet</servlet-name>
    <servlet-class>org.springframework.js.resource.ResouceServlet</servlet-class>
    <load-on-startup>1</load-on-startup>
</servlet>
<servlet-mapping>
    <servlet-name>Resource Servlet</servlet-name>
    <url-pattern>/resources/*</url-pattern>
</servlet-mapping>
<servlet-mapping>
    <servlet-name>default</servlet-name>
    <url-pattern>*.css</url-pattern>
</servlet-mapping>
<servlet-mapping>
    <servlet-name>default</servlet-name>
    <url-pattern>*.js</url-pattern>
</servlet-mapping>
