Mobile Path and Root Path not working as expected

[bussien]

I have a little problem with
webmvc_config.xml
<bean class="org.springframework.mobile.device.site.Site PreferenceHandlerInterceptor" />

<!-- On pre-handle, redirects mobile users to "StayAt.org/taxi/mob" (declare after DeviceResolverHandlerInterceptor) -->
<bean class="org.springframework.mobile.device.switcher. SiteSwitcherHandlerInterceptor" factory-method="urlPath">
<constructor-arg index="0" type="java.lang.String" value="/mob" />
<constructor-arg index="1" type="java.lang.String" value="/taxi" />
</bean>
web.xml
<servlet-mapping>
<servlet-name>taxi</servlet-name>
<url-pattern>/</url-pattern>
<url-pattern>/mob/*</url-pattern>
</servlet-mapping>
HelloController
strCurrentSitePreference = request.getParameter("site_preference");
if (strCurrentSitePreference == null) {
Device device = DeviceUtils.getCurrentDevice(request);
// System.out.println("***** org.stayat.web.util.HelloController.isbNormal ***** device "+ device+ " device.isMobile() "+ device.isMobile());
if (device.isMobile()) {
bNormal = false;
strCurrentSitePreference = "mobile";
strTemp = "mobile";
} else {
bNormal=true;
strCurrentSitePreference = "normal";
strTemp = "normal";
}
}else{
if (strCurrentSitePreference.equals("mobile")) {
bNormal = false;
strCurrentSitePreference = "mobile";
strTemp = "mobile";
} else {
bNormal=true;
strCurrentSitePreference = "normal";
strTemp = "normal";
}
}
main.jsf
I have to maintain a separate panel (rendered="#{!helloController.bNormal}") instead of redirecting to a other page e.g. mobile/main.jsf mob.jsf
did I oversee something in the documentation?
thanks for your help

I'm having trouble understanding the issue. Can you describe what is happening, and what are your expectations? Thanks!
