Setting the path of servlet and jsp pages

I have a web application which has the following directory structure:

I have my web.xml as follows:

<web-app>
<context-param>
<param-name>contextConfigLocation</param-name>
<param-value>/WEB-INF/com.gs.fw.mcd*.xml</param-value>
</context-param>
<listener>
<listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
</listener>
<servlet>
        <servlet-name>UtilitiesServlet</servlet-name>
        <servlet-class>com.gs.fw.sox404.utilities.UtilitiesServlet</servlet-class>
        <init-param>
             <param-name>util-log4j-init-file</param-name>
             <param-value>/WEB-INF/classes/util_log4j.properties</param-value>
          </init-param>
        <load-on-startup>1</load-on-startup>
    </servlet>
<servlet-mapping>
        <servlet-name>UtilitiesServlet</servlet-name>
        <url-pattern>/UtilitiesServlet</url-pattern>
    </servlet-mapping>
 
    <filter>
<filter-name>BaseAuthenticationFilter</filter-name>
<filter-class>com.gs.fw.mcd.security.web.GSAuthenticationFilter</filter-class>
</filter>

<filter-mapping>
<filter-name>BaseAuthenticationFilter</filter-name>
<url-pattern>*.jsp</url-pattern>
</filter-mapping>
<filter-mapping>
<filter-name>BaseAuthenticationFilter</filter-name>
<url-pattern>/UtilitiesServlet</url-pattern>
</filter-mapping>

What changes should I do to web.xml so that -

1) after logging into the application, index.jsp is displayed.
2) when i click on any link on index.jsp, it finds the servlet and shows up the next right jsp page with the styles.

index.jsp is -

I have pasted only important pieces of index.jsp.

Right now, what happens is -

1)i login, it does not find index.jsp and it shows up directory structure on the browser as jsp and styles.
2) i click on jsp, it shows up index.jsp, but does not find the stylesheet.
3) in index.jsp, i click on add mcd user, it finds add_mcd_user.jsp but no stylesheet.

The base of your web app should be the folder containing WEB-INF.
