Spring mobile redirect 404 error

Question

I'm building the mobile version of the site with different layout. I'm using Spring mobile+Thymeleaf. For testing purposes, I'm getting redirected from main site to mobile version. Here's my web.xml

<?xml version="1.0" encoding="UTF-8"?>

<web-app version="2.4"
         xmlns="http://java.sun.com/xml/ns/j2ee"
         xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
         xsi:schemaLocation="http://java.sun.com/xml/ns/j2ee
         http://java.sun.com/xml/ns/j2ee/web-app_2_4.xsd" >


<display-name>Student Accounting site</display-name>

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

<servlet>
    <servlet-name>studentacc</servlet-name>
    <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
    <load-on-startup>1</load-on-startup>
</servlet>
<servlet-mapping>
    <servlet-name>studentacc</servlet-name>
    <url-pattern>/</url-pattern>
    <url-pattern>/m/*</url-pattern>
</servlet-mapping>
<filter>
    <filter-name>deviceResolverRequestFilter</filter-name>
    <filter-class>org.springframework.mobile.device.DeviceResolverRequestFilter</filter-class>
</filter>

</webapp>

And here's my servlet.xml

<beans xmlns="http://www.springframework.org/schema/beans"

        <property name="enableFallback" value="true" />
    </bean>
    <!--Other beans init:END-->

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

</beans>

And mine controller:

public class MainController {
    private static final Logger logger = Logger.getLogger(MainController.class.getName());

@RequestMapping(value = "/")
public String HelloWorld(Model model,Device device){
    logger.info("Device is "+device);
    if(device.isNormal()){
        return "hello";
    }
    return "index";
}

}

Mine webapp folder look like this: WEB-INF--- | pages--- | mobile--- | index.html

So, the redirecting work just fine,I'm getting redirected to mobile version. But page i'm redirected to is non existing(404). I' just can't see the error. Thank you in advance.

Answer 1

"rotate" the redirect to url to sitename:8080/studentacc/m" because it is likely that "studentacc" is the name of your application in the application server, and therefore it must be the first part.

From a very short look to the API, I would try to use the SiteSwitcherHandlerInterceptor.urlPath(String mobilePath, String rootPath) method with the additional parameter for the rootPath

<bean class="org.springframework.mobile.device.switcher.SiteSwitcherHandlerInterceptor" factory-method="urlPath">
     <constructor-arg value="/m" />
     <constructor-arg value="/studentacc" />
</bean>
