I am trying to set up a Spring project without Maven. My project has to serve jsp pages and json streams via Spring MVC framework. Jsp pages' section works well, but when I try to set up json streaming (in order to make ajax GETs) I get

java.lang.ClassNotFoundException: org.codehaus.jackson.map.ObjectMapper

我的servletname-servlet.xml文件如下：

My servletname-servlet.xml is the following:

</bean>

<mvc:resources mapping="/css/**" location="/css/" />
<mvc:resources mapping="/img/**" location="/img/" />
<mvc:resources mapping="/js/**" location="/js/" />

</beans>

我的控制器是以下

My controller is the following

package org.package.servletname;

import java.util.LinkedList;
import java.util.List;

import org.package.servletname.orm.*;

import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RequestMethod;
import org.springframework.web.bind.annotation.ResponseBody;

@Controller
@RequestMapping("/ajax")
public class JSONGetController
{
@RequestMapping(value = "/getproducts", method = RequestMethod.GET)
public @ResponseBody
List<Product> JSONGetProducts()
{
    List<Product> productList = null;
    Product p = new Product();
    p.setName("ProductName");
    productList = new LinkedList<Product>();
    productList.add(p);
    return productList;
}
}
