application-config.xml:

JSP page:

<form:form method="POST" action="/QuickBooks-UX/syncAccounts">
<input type="submit" value="Sync Account"/>
</form:form>


Controller:

@Controller
@RequestMapping("/")
public class QuickBooksController {
@RequestMapping(value = "/quickBooks", method = RequestMethod.GET)
public String qucikBooks(ModelMap model) {
logger.info("Welcome to QuickBooks controller");
model.addAttribute("message", "Hello Spring MVC Framework!");
return "quickBooks";
}
@RequestMapping(value ="/syncAccounts", method = RequestMethod.POST)
public @ResponseBody List<SyncData> syncAccounts(@ModelAttribute("syncData")SyncData syncData, ModelMap model, BindingResult result) {
List<SyncData> syncDataList = new ArrayList<SyncData>();
try {

DefaultHttpClient httpClient = new DefaultHttpClient();
HttpGet getRequest = new HttpGet(
"http://localhost:8292/qbsyncdata/getAccounts");
getRequest.addHeader("accept", "application/json");

HttpResponse response = httpClient.execute(getRequest);
if (response.getStatusLine().getStatusCode() != 200) {
throw new RuntimeException("Failed : HTTP error code : "
+ response.getStatusLine().getStatusCode());
}
BufferedReader br = new BufferedReader(
new InputStreamReader((response.getEntity().getContent())));
while ((output = br.readLine()) != null) {
JSONParser jsonParser = new JSONParser();
JSONArray jsonArray = (JSONArray)jsonParser.parse(output);
for (Object object : jsonArray) {
JSONObject jsonObject = (JSONObject)object;
syncData = new SyncData();
syncData.setAccountName(jsonObject.get("accountName")==null?"":jsonObject.get("accountName").toString());
syncData.setAccountType(jsonObject.get("accountType")==null?"":jsonObject.get("accountType").toString());
syncData.setAccountSubType(jsonObject.get("accountSubType")==null?"":jsonObject.get("accountSubType").toString());
syncData.setActive(jsonObject.get("active")==null?"":jsonObject.get("active").toString());
syncDataList.add(syncData);
}
model.addAttribute("syncData", output);
}
httpClient.getConnectionManager().shutdown();
} catch (Exception e) {
e.printStackTrace();
}
}
return syncDataList;
}
}


I am invoking my url as :

http://lt-50k7sy1:8080/QuickBooks-UX/quickBooks


After clicking the button, which returns the url as
http://lt-50k7sy1:8080/QuickBooks-UX/syncAccounts
this returns 406 and description is:


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


I have followed this Link, but no results.
