Problem with spring security Login

I'm developing login page with spring security but when I start my project automatically redirected to the login page. I've a in my web.xml with redirect to index.xhtml, why is redirect to login.xhtml?

web.xml

Code:

---

<web-app >
<display-name>AirTour</display-name>

<welcome-file-list>
    <welcome-file>index.xhtml</welcome-file>
</welcome-file-list>

<!-- SPRING -->

<context-param>
    <param-name>contextConfigLocation</param-name>
    <param-value>
        /WEB-INF/conf/applicationContext.xml
    </param-value>
</context-param>

<listener>
    <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
</listener>
<listener>
    <listener-class>org.springframework.web.context.request.RequestContextListener</listener-class>
</listener>
