using JQuery with Spring 3

[John Eric Hamacher]

Spring 3.0.5
jQuery 1.5.2

Hello:

I have been trying to make an ajax call with jQuery:

	    $.getJSON("test/sample", { name: $('#name').val() }, function(data) {
	    	alert('data.name = ' + data.name);
	    	$('#result').html(data.name);
	    });

My controller:

package com.fantasypro.mvc.controller;

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.RequestParam;
import org.springframework.web.bind.annotation.ResponseBody;

import com.fantasypro.mvc.entity.ajax.Hello;

@Controller
@RequestMapping(value="/test")
public class SampleController {

	
	@RequestMapping(value="/sample", method=RequestMethod.GET)
	public @ResponseBody Hello appendHello(@RequestParam String name) {
		
		Hello hello = Hello.hello(name);
		return hello;
	}
}

I followed the example at http://blog.springsource.com/2010/01/25/ajax-simplifications-in-spring-3-0/ but I'm missing something. The communication gets lost sometime in the response . . . the callback never fires.

Can somebody give me a hint?

Thanks
Eric

I would try making the equivalent request without ajax to see if it caused an error and hence prevented the output from being delivered. One way to test web-service calls (well, besides regular GET requests) is to use Firefox' POSTER plugin (https://addons.mozilla.org/en-us/firefox/addon/poster/). Additionally, give jquery a chance to notify you of the error with an error callback (see http://stackoverflow.com/questions/1740218/error-handling-in-getjson-calls for information on that)

Page-relative URLs are always suspect and fragile.

Thanks, I get a 406 response "Not Acceptable". I'm looking into that now . . . .

[John Eric Hamacher]

Can't solve this 406 . . . added "headers" to @RequestMapping

	@RequestMapping(value="/sample", headers="{Accept=application/json, text/javascript, */*}", method=RequestMethod.GET)
	public @ResponseBody Hello appendHello(@RequestParam String name) {
		
		Hello hello = Hello.hello(name);
		return hello;
	}

I put the Jackson jar in my classpath as was recommended.

[John Eric Hamacher]

I figured it out. There are two Jackson jars, core and mapper. You need both in your classpath.


Thanks for the help!
