change the return type in your spring class to Object instead of product and add contentType: "application/json" to your AJAX call.

I have changed the return type in the spring controller class to Object instead of product and added contentType: "application/json" to the AJAX call. The error message is same: http://localhost:8080/MyShoppingCart/getAjaxProductInfo.htm 406 (Not Acceptable)

Spring code:

The jquery code:

<%@page contentType="text/html" pageEncoding="UTF-8"%>
<%@ taglib prefix="c" uri="http://java.sun.com/jsp/jstl/core" %>

<!DOCTYPE html>

Can you try adding produces attribute to your RequestMappinglike this, @RequestMapping(value = "/getAjaxProductInfo.htm", method = RequestMethod.POST,produces="application/json").

Also, can you show us your classpath libraries..

I did that and got same error message.

The classpath:

antlr-2.7.7.jar
commons-logging.jar
dom4j-1.6.1.jar
jquery-2.0.3.js
jquery-2.0.3.min.js
jquery-2.js
jstl.jar
org.springframework.asm-3.1.1.RELEASE.jar
org.springframework.beans-3.1.1.RELEASE.jar
org.springframework.context-3.1.1.RELEASE.jar
org.springframework.context.support-3.1.1.RELEASE.jar
org.springframework.core-3.1.1.RELEASE.jar
org.springframework.expression-3.1.1.RELEASE.jar
org.springframework.web-3.1.1.RELEASE.jar
org.springframework.web.servlet-3.1.1.RELEASE.jar
standard.jar

I also tried adding jackson-all-1.9.0.jar to the classpath.

I got some response when using a GET request and sending a string "hello" in request from the browser. I do not need a single string like hello to be displayed in my HTML but need some properties of Product like product.price, product.type etc. But when sending Product as response there is error message :

The resource identified by this request is only capable of generating responses with characteristics not acceptable according to the request "accept" headers ()

My Spring controller code:

So the issue is I am able to send Hello a single string in the response using below url

http://localhost:8080/MyShoppingCart/getAjaxResponse.htm?productId=abc

but I need more information to be displayed in HTML like product.price, product.type.

thanks

You have to register the MappingJacksonHttpMessageConverter as below and add <mvc:annotation-driven/> to your spring configuration file.

I am able to get AJAX response onto the JSP page as below. However this way I am only able to pass the product.getPrice() as the AJAX response whereas I want to pass product.getType() also along with product.getPrice().

and the Spring controller code:

This works fine. However this way I am only able to pass the product.getPrice() as the AJAX response whereas I want to pass product.getType() also along with product.getPrice(). How can this be done ?

thanks
