AJAX POST Request returning 404 on Spring MVC
===

I'm working on a project where I need to submit a JSOn object using AJAX to Spring controller. But I'm getting 404 on submission. Please, can somebody tell me what the problem is:

My AJAX Request :

		$.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();
                }
            });
		}
    }

My Controller :

	@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;	
	}


My 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>
</web-app>


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>
</beans>


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

If directory structure helps :

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


index.jsp is able to call checkDetails.jsp. Also, there is no problem with AJAX JSON submission, the application is working perfectly when m not implementing it as a Spring MVC.

Do I need to add another mapping for it ?
