AJAX POST Заявка, връщаща 404 на Spring MVC

Работя по проект, в който трябва да изпратя JSOn обект с помощта на AJAX към Spring контролера. Но получавам 404 при подаване. Моля, някой може ли да ми каже какъв е проблема:

Моята AJAX заявка:

    $.ajax({
        url: 'NewTestApp/chkDetails/',
        type : 'POST',
        data : 'pwd='+ p,       
        timeout: 15000,
        async : false,
        dataType: 'json',
                success: function (data, textStatus, jqXHR) {
                    displayThings(data);
                },
                error: function (jqXHR, textStatus, errorThrown) {
                    $('#error').show();
            }
        });
    }
}

Моят контролер:

@RequestMapping(value = "/chkDetails", method = RequestMethod.POST)
@ResponseBody
public JSONObject getDetails(@RequestParam(value = "pwd")Object sPassword) throws IOException, ParseException
{
    JSONObject obj = (JSONObject) JSONValue.parse(sPassword.toString());
    JSONObject retObj;

    if(obj.isEmpty())
    {
        System.out.println("hihi");
    }       
    retObj = chk.chkStrength(obj);
    return retObj;  
}

Моят web.xml:

<servlet>
    <servlet-name>spring</servlet-name>
    <servlet-class>
        org.springframework.web.servlet.DispatcherServlet
    </servlet-class>
    <load-on-startup>1</load-on-startup>
</servlet>
<servlet-mapping>
    <servlet-name>spring</servlet-name>
    <url-pattern>*.html</url-pattern>
</servlet-mapping>
<context-param>
    <param-name>contextConfigLocation</param-name>
    <param-value>/WEB-INF/spring-servlet.xml</param-value>
</context-param>

and My spring-servlet.xml :

<context:component-scan
    base-package="main.pwd.controller" />


<bean id="viewResolver"
    class="org.springframework.web.servlet.view.InternalResourceViewResolver">
    <property name="suffix" value=".jsp" />
    <property name="prefix" value="/WEB-INF/jsp/" />
</bean>

<bean id="urlMapping" class="org.springframework.web.servlet.handler.SimpleUrlHandlerMapping">
    <property name="urlMap">           
        <map>
            <entry key="/checkDetails.html">
                <ref bean="PasswordServiceController"/>
            </entry>
        </map>
    </property>

</bean>
  <bean id="PasswordServiceController" class="main.pwd.controller.PasswordServiceController"> </bean>

I'm very new to spring and this is my first project. Pretty sure I've done something wrong with the mapping.

Ако структурата на директорията помага:

NewTestApp | Уеб съдържание | |-WEB-INF | | | |-web.xml | |-spring-servlet.xml | |-jsp | | | |- checkDetails.jsp |-index.jsp

index.jsp може да извика checkDetails.jsp. Освен това няма проблем с подаването на AJAX JSON, приложението работи перфектно, когато не го внедрявам като Spring MVC.

Трябва ли да добавя друго картографиране за него?
